Facility ID Number for Broadcast Stations
-- A unique number has been assigned to each AM, FM, LPFM, TV, LPTV,
translator, and booster station. This number
is being employed to provide an unvarying reference between
various databases at the Commission, and to minimize discrepancies caused
by call sign or facilities changes. The Facility ID Number for a broadcast
station may be determined by using CDBS. We encourage the use of this number, along with the station
call sign and file number if appropriate,
on the cover page of all documents pertaining to particular
broadcast stations submitted to the FCC.
Fees and Regulatory Fees -- Fees are applicable to
commercial applicants only.
