This order responds to the Florida Public Service Commission's (Florida Commission) April 2, 1999, Petition for Expedited Decision for Grant of Authority to Implement Number Conservation Measures (Petition) requesting additional authority from the Commission to implement various area code conservation measures in the state of Florida. We herein conditionally grant the Florida Commission the authority to institute thousands- block pooling trials; reclaim unused and reserved NXX codes, and portions of those codes; maintain rationing procedures for six months following area code relief; set numbering allocation standards; and require the submission of utilization data from all carriers; and implement NXX code sharing. We reiterate that consolidating rate centers/areas already is within the authority of the Florida Commission. Therefore, while no action on our part appears to be necessary with respect to this aspect of the Florida Commission's request, we grant the Florida Commission's request for any additional authority it may need to consolidate rate centers to optimize the use of numbering resources. We deny the Florida Commission's requests for authority to implement unassigned number porting; to order carriers to expand deployment of LNP; and to direct the NANPA to conduct quarterly Central Office Code Utilization Surveys (COCUS). The Florida Commission may, however, undertake such surveys itself. We decline to reach the Florida Commission's requests to revise NXX code rationing procedures and to institute rationing prior to arriving at an area code relief plan at this time. Although we grant the Florida Commission interim authority to institute many of the optimization measures raised in its Petition, this grant will be superseded by forthcoming decisions in the Numbering Resource Optimization proceeding that will establish national guidelines, standards, and procedures for numbering optimization. Thus, this limited grant of delegated authority should not be construed as prejudging any of the issues on which the Commission has sought public comment in the Numbering Resource Optimization Notice. II.BACKGROUND 3. Congress granted the Commission plenary jurisdiction over numbering issues. Section 251(e)(1) of the Act also allows the Commission to delegate to state commissions all or any portion of its jurisdiction over numbering administration. The Commission's regulations generally require that numbering administration: (1) facilitate entry into the telecommunications marketplace by making telecommunications resources available on an efficient and timely basis to telecommunications carriers; (2) not unduly favor or disfavor any particular industry segment or group of telecommunications consumers; and (3) not unduly favor one telecommunications technology over another. Further, our regulations specify that, if the Commission delegates any telecommunications numbering administration functions to any state, the states must perform the functions in a manner consistent with these general requirements. 4. On September 28, 1998, the Commission released the Pennsylvania Numbering Order delegating additional authority to state commissions to order NXX code rationing in conjunction with area code relief decisions, in the absence of industry consensus. The order further approved a mandatory thousands-block number pooling trial in Illinois. The order provided that state utility commissions could order voluntary pooling trials, but in view of the Commission's efforts to develop national pooling standards, we declined to delegate to state commissions the general authority to order mandatory number pooling. The Pennsylvania Numbering Order, however, encouraged state commissions to seek further limited delegations of authority to implement other innovative number conservation methods prior to implementing number conservation plans. 5. In its Petition, the Florida Commission requests that the Commission grant it the authority to: (1) institute thousands-block number pooling; (2) implement NXX code sharing within rate centers; (3) revise rationing procedures and institute NXX lotteries prior to adopting an area code relief plan; (4) reclaim unused and reserved NXX codes; (5) maintain NXX code rationing measures for six months following implementation of area code relief plans; (6) expand deployment of permanent LNP; (7) implement unassigned number porting; (8) consolidate rate centers; and (9) require all carriers to submit utilization data at the thousands-block level. In addition, the Florida Commission requests that this Commission direct the NANPA to conduct the Central Office Code Utilization Survey (COCUS) quarterly and establish code allocation standards to more efficiently manage numbering resources. The Florida Commission states that it requests this additional authority as part of its ongoing area code relief proceeding and to minimize consumer confusion and expenses associated with imposing new area codes too frequently. On April 15, 1999, the Petition was placed on Public Notice for public comment. VI.DISCUSSION 7. We recognize that the area code situation in Florida is critical, with nine new area codes having been added since 1995, six of which may already be in jeopardy. In light of this extreme situation and in order to empower the Florida Commission to take steps to make number utilization more efficient, we herein grant significant additional authority to the Florida Commission. In some instances, we are granting the Florida Commission authority that goes beyond the parameters outlined in the Pennsylvania Numbering Order, because we find such grant to be appropriate in light of the specific circumstances in Florida. 8. Many of the measures proposed in the Florida Commission's Petition are also examined in a Notice of Proposed Rulemaking that this Commission recently released. Although we grant the Florida Commission interim authority to institute many of the optimization measures in the Petition, we do so subject to the caveat that this grant will be superseded by forthcoming decisions in the Numbering Resource Optimization proceeding that will establish national guidelines, standards, and procedures for numbering optimization. This limited grant of delegated authority should not be construed as a prejudgment of any of the measures on which the Commission has sought public comment in the Numbering Resource Optimization Notice. 9. Congress granted this Commission exclusive jurisdiction over those portions of the North American Numbering Plan (NANP) that relate to the United States, and directed that the Commission administer the NANP in a manner which assures that numbering resources are available on an equitable basis. The Commission was also granted the authority to delegate this jurisdiction to state utility commissions. Thus, while we grant authority below to the Florida Commission to engage in various matters related to administration of the NANP in Florida, we require the Florida Commission to abide by the same general requirements that this Commission has imposed on the numbering administrator. Thus, the Florida Commission, to the extent it acts under the authority delegated herein, must ensure that numbers are made available on an equitable basis; that numbering resources are made available on an efficient and timely basis; that whatever policies the Florida Commission institutes with regard to numbering administration not unduly favor or disfavor any particular telecommunications industry segment or group of telecommunications consumers; and that the Florida Commission not unduly favor one telecommunications technology over another. 10. The grants of authority herein are not intended to allow the Florida Commission to engage in number conservation measures to the exclusion of, or as a substitute for, unavoidable and timely area code relief. While we are giving the Florida Commission tools that may prolong the lives of existing area codes, the Florida Commission continues to bear the obligation of implementing area code relief when necessary, and we expect the Florida Commission to fulfill this obligation in a timely manner. Under no circumstances should consumers be precluded from receiving telecommunications services of their choice from providers of their choice for a want of numbering resources. For consumers to benefit from the competition envisioned by the Telecommunications Act of 1996, it is imperative that competitors in the telecommunications marketplace face as few barriers to entry as possible. 11. Several commenting parties urged the Commission to grant the Florida Commission's Petition in its entirety on the basis that state utility commissions require greater authority to implement number conservation measures in order to rectify the causes of area code exhaust. Other parties suggested that we deny the Petition on the basis that number conservation measures must be developed at the national level, and that the Petition does not provide an adequate basis on which to grant the requested delegations of authority. 12. Thousands-block number pooling. The Florida Commission requests authority to institute thousands-block number pooling. This Commission has tentatively concluded that thousands-block pooling is an important numbering resource optimization strategy, essential to extending the life of the NANP. In granting the Illinois Commission the authority to engage in a mandatory thousands-block pooling trial in the Pennsylvania Numbering Order, this Commission recognized that state number pooling trials could aid in developing national pooling implementation, architecture, and administrative standards. The Florida Commission, noting that development of nationwide thousands-block pooling rules may take considerable time, requests the authority to implement its own thousands-block pooling requirements in advance of any federal rules. 13. Commenters representing incumbent local exchange carriers oppose permitting state utility commissions to order thousands-block pooling trials, mainly on the basis that multiple, inconsistent trials would pose an administrative burden to carriers that are present in various states. Several wireless carriers have also voiced their opposition to thousands- block pooling trials based on the premise that such trials would require the implementation of local number portability (LNP). Some competitive local exchange carriers and other state utility commissions have voiced their support for thousands-block pooling trials as a means to allocate numbers more efficiently and ensure that carriers are given greater access to numbering resources. 14. We have been concerned that the existence of multiple pooling trials in a state or region may strain the capacities of carriers' Service Control Points (SCPs), which could affect the ability of carriers' networks to perform LNP and pooling functions. We note, however, that the volume of ported numbers is significantly lower than previously anticipated. 15. Although we remain concerned about the potential strain which multiple thousands-block pooling trials in an MSA, state or region may have on the functioning of the public switched telephone network, we nonetheless believe this relief is appropriate given the strain on Florida's numbering resources. Furthermore, since the release of the Pennsylvania Numbering Order, the telecommunications industry has arrived at detailed guidelines governing the technical and administrative functioning of thousands-block number pooling. In the Pennsylvania Numbering Order, we stated that upon the establishment of uniform, national standards for pooling, we may determine that it is appropriate to delegate to state commissions the additional authority to implement and enforce those standards. We therefore grant authority to the Florida Commission to conduct mandatory thousands-block number pooling trials in Florida. We agree with the concern raised by many wireline commenters, however, that inconsistent pooling trials could pose a burden to carriers. To ameliorate this concern, we direct the Florida Commission to conduct its pooling trials in accordance with industry-adopted thousands-block pooling guidelines. Where the Florida Commission determines that changes, modifications, or departures from the guidelines are desirable, we direct the Florida Commission to consult with the industry prior to implementing such changes. Although we will not dictate the manner in which the Florida Commission should consult with industry, the Florida Commission should at a minimum, seek input from the industry regarding the implications of any proposed changes to the guidelines so that the Florida Commission may be able to weigh the industry's concerns in its decision-making process. 16. We grant this authority subject to the conditions and safeguards similar to those enumerated in the Pennsylvania Numbering Order that granted such authority to Illinois. Thus, we require that in any NPA which is in jeopardy in which the Florida Commission implements a pooling trial, the Florida Commission must take all necessary steps to prepare an NPA relief plan that may be adopted by the Florida Commission in the event that numbering resources in the NPA at issue are in imminent danger of being exhausted. This criterion is not intended to require the Florida Commission to implement an NPA relief plan prior to requiring thousands-block number pooling in Florida. Rather, we require only that the Florida Commission be prepared to implement a "back-up" NPA relief plan prior to the exhaustion of numbering resources in the NPA at issue. Consumers should never be in the position of being unable to exercise their choice of carrier because that carrier does not have access to numbering resources. This criterion attempts to ensure that consumers continue to retain a choice of telecommunications providers in the event that the pooling trial or trials do not stave off the need for area code relief. 17. Only those carriers that have implemented permanent LNP shall be subject to the trial. At the present time, we do not grant the Florida Commission the authority to require a carrier to acquire LNP solely for the purpose of being able to participate in a thousands-block pooling trial. Carriers are only required to implement LNP if requested by another carrier subject to the requirements established by this Commission. Within NPAs that are subject to the pooling trial, non-LNP capable carriers shall have the same access to numbering resources after pooling is implemented that they had prior to the implementation of a pooling regime, i.e., non-LNP capable carriers shall continue to be able to obtain full NXX codes. We recognize that conditioning the Florida Commission's authority to implement a mandatory thousands-block pooling trial on exemption of non-LNP capable carriers from participation in the trial will create a disparity in the way different types of service providers obtain access to numbering resources, in tension with the criteria set forth above. In order to ensure that consumers may continue to obtain service from non-LNP capable carriers of their choosing, however, we find that for the purposes of this interim delegation, it is necessary to safeguard these carriers' access to numbering resources, while they lack the technical capability to participate in pooling. The Numbering Resource Optimization Notice raises a number of issues relating to non-LNP capable carriers' participation in pooling, and we believe these issues are best addressed in the larger rulemaking context. In the meantime, we suggest to the Florida Commission that it urge the non-LNP capable carriers to use various other numbering resource optimization strategies such as those discussed in the Numbering Resource Optimization Notice to improve the efficiency of numbering resources assigned to such carriers. 18. We direct the Florida Commission to ensure that an adequate transition time is provided to carriers to implement pooling in their switches and administrative systems. Thousands-block pooling requires carriers to alter significantly the manner in which they account for their inventory of telephone numbers, including changing their Operations Support Systems (OSSs) and retraining their staffs. In addition, we also urge the Florida Commission not to require carriers to engage in processes related to thousands-block pooling which might divert critical resources away from preparations related to the Year 2000 rollover. 19. We further require that the Florida Commission determine the method to recover the costs of the pooling trials. The Florida Commission must also determine how carrier- specific costs directly related to pooling administration should be recovered. The Commission has tentatively concluded that thousands-block number pooling is a numbering administration function, and that section 251(e)(2) authorizes the Commission to provide the distribution and recovery mechanisms for the interstate and intrastate costs of number pooling. We conclude that inasmuch as we are hereby delegating numbering administration authority to the Florida Commission, the Florida Commission must abide by the same statute applicable to this Commission, and, therefore, ensure that costs of number pooling are recovered in a competitively neutral manner. We note that the Telephone Number Portability proceeding found that section 251(e)(2) requires all carriers to bear the costs of number portability on a competitively neutral basis, and, thus, established a cost recovery mechanism that assesses even carriers that cannot or have not implemented LNP to date. The Florida Commission may consider the recently released Telephone Number Portability Order for guidance regarding the criteria with which a cost recovery mechanism must comply in order to be considered competitively neutral: First, "a 'competitively neutral' cost recovery mechanism should not give one service provider an appreciable, incremental cost advantage over another service provider, when competing for a specific subscriber." Second, the cost recovery mechanism "should not have a disparate effect on the ability of competing service providers to earn normal returns on their investments." Consistent with our treatment of cost recovery in the Telephone Number Portability proceeding, we believe that even those carriers that cannot participate in pooling at this time will benefit from the more efficient use of numbering resources that pooling will facilitate. We also encourage the Florida Commission to consider the "road map" provided by the Numbering Resource Optimization Notice regarding cost recovery for thousands-block number pooling. 20. In order to minimize possible disruption and expense and maximize the value of the information that can be obtained from number pooling trials, we believe that such trials should be limited in nature. As an initial matter, we limit the authority we grant to the Florida Commission to a trial that generally covers one Metropolitan Statistical Area (MSA). We believe that such a limitation strikes the appropriate balance among the Florida Commission's desire to move quickly to implement measures that will enhance number utilization efficiency, and possibly prolong the lives of certain area codes in Florida, and our obligation to ensure that such pooling trials are implemented and conducted in a manner that does not disrupt network operations or reliability. We believe these goals ultimately benefit consumers in Florida by allowing the Florida Commission to move forward with pooling trials quickly in whatever area it determines it is most necessary, while providing some assurance that the network changes required for the trials are implemented in a manner that does not disrupt the normal functioning of the network in Florida and nationwide. 21. After having implemented a thousands-block number pooling trial in one MSA, the Florida Commission may wish to expand to another MSA. Should it wish to do so, we direct the Florida Commission to allow sufficient transition time for carriers to undertake any necessary steps, such as modifying databases and upgrading switch software, to prepare for an expansion of thousands-block pooling to another MSA. In other words, start dates for thousands-block pooling trials in different MSAs should be appropriately staggered to permit the industry to undertake all necessary steps. The purpose of a staggered roll-out is to provide carriers time to upgrade or replace their SCPs and other components of their network, as necessary, if the increased volume of ported numbers as a result of the pooling trial requires them to do so. 22. We suggest to the Florida Commission that it consider concentrating its thousands-block pooling trial in those NPAs which are the best candidates for pooling, based on the considerations set forth in the Numbering Resource Optimization Notice. For example, we encourage the Florida Commission to consider number pooling in areas where multiple, LNP-capable carriers exist. We also suggest to the Florida Commission that it allow for exceptions to participating in a pooling trial, if doing so would prove prohibitively expensive to a particular carrier. For example, certain switch types may not be able to accommodate thousands-block number pooling. Finally, as we stated in the Numbering Resource Optimization Notice, we encourage the Florida Commission, to the extent it has not already done so, to consider consolidating rate centers prior to implementing pooling. Fewer, larger pools logically increase the effectiveness of thousands-block pooling. 23. We reiterate that the authority we grant herein to the Florida Commission to undertake thousands-block pooling trials is interim in nature, and is in no way intended to relieve the Florida Commission of its obligation to implement necessary area code relief in a timely fashion. Whatever decisions this Commission reaches with regard to thousands-block pooling administration and guidelines will supersede whatever systems the Florida Commission puts in place prior to enactment of those rules. 24. Reclamation of unused and reserved NXX codes. The Florida Commission also requests the authority to reclaim unused and reserved NXX codes in Florida, noting that the possibility of reclaiming reserved NXX codes for future distribution could extend the lives of existing area codes. The CO Code Assignment Guidelines provide that carriers shall activate NXXs within six months of the "initially published effective date." Most commenters support the reclamation of unused codes, and those opposed to this delegation are not necessarily opposed to reclaiming unused codes in general, but rather assert that the NANPA is responsible for reclamation activities. Reclaiming NXX codes that are not in use may serve to prolong the life of an area code, because these codes are added to the total inventory of assignable NXX codes in the area code. Therefore, we grant authority to the Florida Commission to investigate whether code holders have activated NXXs assigned to them within the time frames specified in the CO Code Assignment Guidelines, and to direct the NANPA to reclaim NXXs that the Florida Commission determines have not been activated in a timely manner. This authority necessarily implies that the Florida Commission may request proof from all code holders that NXX codes have been "placed in service" according to the CO Code Assignment Guidelines. We further direct the NANPA to abide by the Florida Commission's determination to reclaim an NXX code if the Florida Commission is satisfied that the code holder has not activated the code within the time specified by the CO Code Assignment Guidelines. 25. We note that the CO Code Assignment Guidelines dictate substantial procedural hurdles prior to reclaiming an unused NXX, in part to afford the code holder an opportunity to explain the circumstances that have led to a delay in code activation. New entrants, in particular, may suffer unexpected delays or scheduling setbacks beyond their control, which lead to code activation delays. We clarify that the Florida Commission need not follow the reclamation procedures set forth in the CO Code Assignment Guidelines relating to referring the issue to the Industry Numbering Committee (INC), as long as the Florida Commission accords the code holder an opportunity to explain the extenuating circumstances, if any, behind the unactivated NXX codes. 26. Reclamation of blocks of 1,000 numbers with no contamination, or a relatively low contamination rate, has the potential to add significant numbering resources in areas where thousands-block number pooling has been implemented. To the extent we have delegated the authority to initiate thousands-block number pooling trials, we also delegate authority to the Florida Commission to reclaim unused thousands blocks in connection with such trials. The conditions that apply to the implementation of a thousands-block number pooling trial shall also apply to any reclamation of unused blocks of numbers. In particular, the industry's guidelines regarding reclamation of thousands blocks shall apply to the Florida Commission. 27. Maintenance of rationing procedures for six months following area code relief. The Florida Commission requests the authority to maintain current NXX code rationing measures for six months following area code relief. It states that this authority would be used to control the accelerated demand for NXX codes in the relieved area code that accompanies the announcement of an area code relief plan. 28. Although most industry parties are opposed to granting an extension of rationing procedures because it delays needed area code relief and thereby inhibits carriers' ability to obtain numbering resources with which to serve customers, there is a competitive LEC that contends that allowing an additional six months of rationing would not cause undue harm to any carrier. 29. The Pennsylvania Numbering Order stated that state commission implementation of number conservation measures could not be used "as substitutes for area code relief or to avoid making difficult and potentially unpopular decisions on area code relief." Requesting a continuation of rationing after area code relief has been implemented does not contradict the Pennsylvania Numbering Order, as the requisite area code relief has, in fact, been implemented. This measure seeks only to provide "breathing room" to state commissions that have just undergone the difficult process of implementing a new area code. Furthermore, a limitation of six months does not have the potential in contrast to rationing prior to area code relief to forestall area code relief indefinitely. 30. Where area code relief takes the form of an area code split, we grant the Florida Commission the authority to direct that whatever rationing plan was in place prior to area code relief continue to be applied in both the newly implemented area code and the relieved area code for a period of up to six months following the area code relief date. Correspondingly, if the area code relief is in the form of an overlay, the Florida Commission may direct that the pre-existing rationing plan be applied to both the overlay code and the relieved code for a period of six months following the area code relief date. For reasons discussed in paragraph 38 below, we limit this authority to continuing the pre-NPA relief rationing procedures. Whether the rationing plan in place prior to relief was an industry consensus plan, or whether it was a state commission-ordered plan, only those terms in place prior to area code relief may remain in place for up to six months following area code relief. The Florida Commission may order a continuation of rationing for up to six months, but neither the Florida Commission, nor the telecommunications industry participants in a consensus plan may alter the terms of the rationing plan. We find this limitation appropriate to prevent a potentially contentious re-opening of the terms of a previously settled code rationing plan, resulting in uncertainty and a drain on resources. 31. Setting NXX code allocation standards. The Florida Commission requests that this Commission direct the NANPA to establish code allocation standards to manage numbering resources more efficiently. In the context of the Numbering Resource Optimization proceeding, we may in the future establish code allocation standards that differ from the months-to-exhaust standard that currently exists. We agree with the Florida Commission that extension of this authority to non-jeopardy NPAs will encourage more efficient use of NXX codes. Subject to the conditions set forth below, we hereby delegate authority to the Florida Commission to require NXX code applicants to demonstrate that they have met certain fill rates prior to obtaining additional numbering resources, even in NPAs which are not in jeopardy. Specifically, the Florida Commission may require that carriers achieve a certain fill rate in growth NXX codes and within thousands blocks, in areas where it has implemented thousands-block pooling. 32. Notwithstanding this grant of authority to the Florida Commission, we remain very concerned about the potential competitive impact of imposing a fill-rate regime on carriers' ability to serve customers. A strict fill-rate regime may not accommodate customers' requests for specific numbers or specific ranges of numbers. This concern and others about the use of fill rates as opposed to the industry's current "months-to-exhaust" model are set forth in the Numbering Resource Optimization Notice. In this light, although we do not wish to dictate the parameters of the fill-rate regime, we urge the Florida Commission to allow for some flexibility in establishing fill rates and applying them to carriers. Our primary concern, therefore, is that fill rates not be applied in such a manner as to deprive customers of their choice of carriers from whom to purchase service upon request. 33. We are also concerned about the impact of multiple, disparate number conservation regimes on the availability of telecommunications services and the industry's ability to forecast and plan properly for exhaust of the NANP. Therefore, during its implementation of this authority, we ask that the Florida Commission consult and coordinate with other state commissions that may obtain authority to impose fill rates. We encourage the Florida Commission to establish fill rates that are not inconsistent with those imposed by other states. 34. Despite these concerns, we recognize the need to address the critical situation in Florida. In setting certain guidelines for the Florida Commission to follow, we hope to allay concerns about possible competitive impacts, while enabling the Florida Commission to adopt a quantifiable means of ensuring that carriers are using their numbers with maximum efficiency. 35. First, the Florida Commission may only consider a carrier's fill rate in relation to growth codes. We do not believe that a carrier's ability to establish a service "footprint" should be restricted. That is, a carrier ought to be able to obtain initial numbering resources in rate centers where the carrier is authorized to offer service and plans to do so within the NXX activation timeframe established by the CO Code Assignment Guidelines (six months). We wish to avoid imposing barriers to competitive entry into the telecommunications marketplace. A carrier that is newly providing service may not be able to achieve a prescribed fill rate in an NXX code (or thousands-block, if the numbering request is in an area where the Florida Commission has instituted thousands-block number pooling) for quite some time. With respect to fill rates, however, we conclude that the importance of bringing choice to consumers outweighs the numbering inefficiencies experienced by new entrants. 36. Second, as stated in the Pennsylvania Numbering Order, we are concerned that granting this request and other, similar requests will overburden the NANPA, which based its bid for providing number administration services on industry guidelines that are applicable nationwide. Therefore, to avoid imposing an additional burden on the NANPA, to the extent that the Florida Commission chooses to implement a fill-rate requirement, we delegate authority to the Florida Commission to ascertain carrier compliance with the fill-rate requirement. To avoid delay in NXX code application processing, we direct the Florida Commission to conduct its review of carrier compliance with any required fill rate within the ten-day timeframe established by the CO Code Assignment Guidelines as the time in which the NANPA must respond to an applicant's NXX code request. Of course, a carrier's failure to provide the Florida Commission with adequate evidence of compliance with the fill-rate requirement upon request will toll the running of this 10-day timeframe. Further, while we delegate to the Florida Commission the authority to request and evaluate information provided by carriers to demonstrate compliance with the fill rate, we request that the Florida Commission not release such information to any entity other than the NANPA, this Commission, or the Common Carrier Bureau. 37. The Florida Commission also requests that it be allowed to use the Line Number Utilization Survey (LINUS) to run NXX code reports quarterly, that the FCC direct the NANPA to update the COCUS quarterly, and that the FCC direct wireless carriers to provide necessary telephone number utilization information at the thousands-block level. In the Numbering Resource Optimization Notice, this Commission sought public comment on both the frequency and the level of detail in which carriers should report data relating to their utilization of numbering resources. Thus, at this time we decline to grant the Florida Commission the authority to direct the NANPA to use LINUS in Florida and to direct the NANPA to update the COCUS quarterly. Nonetheless, we recognize the desire of the Florida Commission to obtain information relating to carriers' utilization of numbering resources both to aid it in planning for area code relief and for investigating the feasibility of thousands-block number pooling. 38. We therefore delegate to the Florida Commission the authority to conduct number utilization surveys from all carriers in order to help it plan area code relief projects and to determine the feasibility of pooling scenarios. We reiterate, however, that because this is a topic of the Numbering Resource Optimization Notice, this grant of authority is limited in duration until such time as this Commission enacts rules or policies relating to collecting data on carriers' use of numbering resources. We do not authorize the Florida Commission to direct the NANPA to undertake such surveys as part of its required functions. 39. NXX code sharing. The Florida Commission also requests the authority to "implement sharing of NXX codes in rate centers." The Florida Commission has not provided any details with regard to how it would implement NXX code sharing, nor do there exist any industry guidelines on this numbering optimization measure. As we stated in the Numbering Resource Optimization Notice, we are interested in the possibility of NXX code sharing as a means to enable non-LNP-capable carriers to participate in or approximate the effect of pooling without requiring them to develop LNP capability. We note that the Colorado Public Utilities Commission has studied NXX code sharing as a number optimization method, and we encourage the Florida Commission to consult with members of the Colorado Commission and other state commissions, who may be familiar with this issue. We therefore encourage the Florida Commission to conduct a study regarding the technical and economic feasibility of NXX code sharing, its implications for the delivery of emergency services, and network impacts of NXX code sharing in Florida. We also encourage the Florida Commission to keep us informed of the results of its investigation on NXX code sharing. We permit the Florida Commission to implement NXX code sharing on a trial basis if the Florida Commission finds that NXX code sharing is technically and economically feasible, as well as cost effective. 40. Rate Center Consolidation. The Florida Commission also requests the authority to consolidate rate centers. Rate center consolidation involves creating larger geographic areas in which individual NXX codes can be used by consolidating or combining existing rate centers. Because many carriers, particularly competitive local exchange carriers, require NXX codes in most or all rate centers in an NPA to establish a competitive "footprint," establishing larger rate centers has significant potential to reduce the demand for NXX codes. Rate center consolidation, as it involves matters relating to local calling scopes and local call rating, falls under state utility commissions' rate-making authority. However, since rate center consolidations have the potential to increase the efficiency of utilization of numbering resources over which we have plenary jurisdiction, we grant the Florida Commission's request for any additional authority it may need to consolidate rate centers since such consolidations will aid the Commission's efforts in optimizing the use of numbering resources. 41. Revision of rationing procedures. The Florida Commission has also sought the authority to revise rationing procedures now in effect expressly for the purpose of prolonging the lives of existing area codes. Although the Florida Commission may order and revise rationing processes where it has ordered area code relief, established a relief date, and the industry has been unable to reach consensus on a rationing plan, rationing of NXX codes should only be for the express purpose of extending the life of the area code until the date of area code relief implementation. As determined in the Pennsylvania Numbering Order, state commissions may not use rationing as a substitute for area code relief. We believe that the authority we are herein delegating to the Florida Commission will provide the Florida Commission the tools it needs to address the underlying behaviors contributing to the inefficiencies of numbering use in Florida. We hope that the Florida Commission's judicious exercise of these measures will, indeed, extend the lives of the area codes at issue in the Petition, as well as whatever new area codes might be introduced in Florida, and we invite the Florida Commission to keep this Commission apprised regarding the efficacy of these measures. Accordingly, at this time, we decline to reach the Florida Commission's request for authority to revise rationing plans put into place pursuant to industry consensus. 42. NXX code lotteries prior to adoption of area code relief plans. The Florida Commission also seeks similar authority to institute NXX code lotteries prior to adopting NPA relief plans. For the reasons stated above, we decline to grant the Florida Commission the broad authority it seeks to adopt rationing measures prior to having decided on a specific plan for area code relief. Again, we believe that the authority we are herein delegating to the Florida Commission will provide it with the tools it needs to address the underlying behaviors contributing to the inefficiencies of numbering use in Florida. 43. Unassigned Number Porting. The Florida Commission requests the authority to implement Unassigned Number Porting (UNP) as an additional tool to conserve numbering resources. As described in the 1998 NANC Numbering Resource Optimization Report (NANC Report), UNP is a telephone number usage optimization measure where available individual telephone numbers in one service provider's inventory are ported, using LNP, to another service provider under the direction of a neutral third party coordinator for assignment by the second service provider to a specific customer. The NANC Report focused on the use of UNP in extreme cases of number shortages, where individual service providers are otherwise completely unable to obtain telephone number to serve customers. The Florida Commission has not provided us with information relating to the details of the proposed use of UNP in Florida. 44. We agree with most of the industry commenters that UNP is currently at too early a stage of development to order implementation. We are also concerned with the impact of UNP on carriers' ability to control their own number inventories. With UNP, because service providers will obtain telephone numbers from other service providers' inventories, the service provider donating numbers may face difficulty forecasting future numbering needs. The NANC Report indicates that many companies' OSSs are designed to accommodate large inventories of telephone numbers, linking each street address to an NPA/NXX combination. If UNP leads to significant number porting, this mapping logic becomes quite difficult to support. We are also concerned with UNP's potential impact on companies' switching systems. UNP may cause problems with switches that can only accept a limited number of NXX codes, as number inventories will be increasingly composed of random telephone numbers from many different NXX codes. For the aforementioned reasons, we decline to grant the Florida Commission's request for authority to implement UNP. 45. We emphasize, however, that our determination not to grant the Florida Commission the authority to order carriers to use UNP does not preclude carriers from voluntarily engaging in UNP where mutually agreeable and where there are no public safety or network reliability concerns. As a matter of fact, we encourage the carriers to do so. Furthermore, we also encourage the Florida Commission to and the carriers to work together to identify and promote other innovative measures as well that would encourage the conservation of NXX codes. XLVI.CONCLUSION 47. We recognize the difficult situation for consumers in Florida, having had to undergo several area code changes in only a few years, with the potential for more on the near horizon. The authority we have herein delegated to the Florida Commission, we hope, will provide it the tools it needs to address the situation. For example, the authority to order thousands-block pooling trials allows the Florida Commission to address inefficiencies on the supply side of the telephone number assignment regime by ordering that LNP-capable carriers receive smaller blocks of numbers than they now do. The authority to address carriers' fill rates allows the Florida Commission to address the demand side of the number assignment regime by requiring that carriers not request more numbering resources until they have used a certain percentage of those already in their inventory. XLVIII.ORDERING CLAUSE 49. Accordingly, pursuant to sections 1, 4(i), and 251 of the Communications Act of 1934, as amended, 47 U.S.C.  151, 154(i), and 251, and pursuant to sections 1.1 and 52.9(b) of the Commission's Rules, 47 C.F.R.  1.1 and 52.9(b), IT IS ORDERED that the Florida Public Service Commission's Petition to Federal Communications Commission for Expedited Decision for Grant of Authority to Implement Number Conservation Measures is GRANTED IN PART and DENIED IN PART to the extent described herein.
