Since the inception of the Cellular Market Areas in 1982, the Federal Communication Commission has been assigning area based radio licenses. A common trait among all of these licensing areas is that every area is an aggregation of county-equivalent entities as defined in Federal Information Processing Standards Publication 6-4, 1990 August 31.
Using this search you can determine in which particular market area your county falls for each of the following market definitions.
1990 County - The first order-division of each State are counties for 48 States, parishes for Louisiana, and boroughs and census areas for Alaska. In addition, the Census Bureau treats the following entities as equivalents of counties for purposes of data presentation: independent cities in Maryland, Missouri, Nevada, and Virginia; the portion of Yellowstone National Park in Montana; "District of Columbia" for the District of Columbia; municipios in Puerto Rico; and a variety of entities in the outlying areas. The 5-digit county geocode consists of a 2-digit State FIPS code and a 3-digit FIPS county code.
All of the data used for this program is available for download from the FCC License Areas web page.
