FCC Area Lookup: Block, Population and Market Area Codes for a Coordinate

fccgeo/area-lookup

Looks up a United States coordinate and returns the block it falls in (15-digit block FIPS code and bounding box), the county and state (FIPS codes and names), the block's 2020 population, and the FCC market-area codes for the block (BEA, BTA, CMA, MTA, PEA and the other codes the service returns). The response also echoes the coordinate and the geography year used. Data from the FCC Area API, passed through unmodified. This product uses the FCC Data API but is not endorsed or certified by the FCC. Served by Eden Engine; not an official FCC product.
