The Wireless Communications and Public Safety Act of 1999 (911 Act) took effect on October 26, 1999. The purpose of the 911 Act is to improve public safety by encouraging and facilitating the prompt deployment of a nationwide, seamless communications infrastructure for emergency services.
One provision of the 911 Act directs the FCC to make 911 the universal emergency number for all telephone services. Where other emergency numbers had been used, the FCC was directed to establish appropriate transition periods for areas in which 911 was not in use as an emergency telephone number.
State and local authorities continue to expand 911 coverage and upgrade 911 services. Although there may be some counties that still do not have basic 911 services, wireless carriers can deliver 911 calls to the appropriate local emergency authority.
Based on these reports, virtually all carriers now use 911 as the universal emergency number and route 911 calls to an appropriate PSAP. However, emergency services through a PSAP may not be available in all localities.
