About

The Federal Communications Commission provides the FCC Area API, a lightweight spatial lookup service that resolves latitude and longitude coordinates into administrative and regulatory geographic boundaries. By querying the service with coordinates, applications retrieve the matching 15-digit Census block FIPS code, county FIPS code, state FIPS code, and FCC spectrum regulatory market designations including Cellular Market Areas (CMAs).

Through Fibric, an operator resolves customer coordinates to exact Census block FIPS codes, proposing regulatory territory tagging or telecommunications compliance classifications for operations teams.

This is a reference listing. It documents what Fibric would read from FCC Area API and what it could propose, based on the publisher's published interfaces. Fibric builds it under a managed deployment when you request it; selecting it here installs nothing.

Inputs

  • 15-digit Census block FIPS code for a coordinate point via GET /api/census/block/find
  • State FIPS code, state abbreviation, and state name from coordinate lookups
  • County FIPS code and county name containing the target geographic point
  • FCC Cellular Market Area (CMA) code and description via GET /api/census/area
  • Benchmark Census block geography mapping supporting 2010 and 2020 decennial vintages

Proposed actions

Read-only. This feed informs operators; it changes nothing.

Proposed actions are target capabilities. Every action runs propose-first and needs a validated deployment and the appropriate permissions.

What you can build

  • Tag customer locations with 15-digit block FIPS

    Convert geocoded delivery coordinates into precise 15-digit Census block codes, proposing demographic tags for location-based reporting.

    With Site Benchmark, Territory Balance

  • Verify telecom regulatory market areas

    Resolve facility coordinates to FCC Cellular Market Area codes, proposing market classification updates to satisfy regulatory spectrum compliance.

    With Compliance Evidence

  • Resolve ambiguous county tax jurisdictions

    When street addresses sit near county boundaries, query coordinates to confirm the exact county FIPS code, proposing accurate sales tax assignments.

    With Customs Declaration, Address Repair

Requirements

  • Latitude and longitude coordinate inputs in standard decimal degrees (WGS 84)
  • Selection of Census vintage parameter (2010 or 2020) according to analytical requirements
  • Network reachability to geo.fcc.gov over standard HTTPS
Authentication
None. The FCC Area API is an open public REST service requiring no registration, credentials, or API keys.

Limits

  • The service supports point coordinate lookups and does not resolve raw street text addresses
  • Coordinates outside US sovereign territory and territorial waters return null block matches
  • Request rates should maintain reasonable polling intervals to prevent automated IP throttling

Questions and answers

What endpoints does the FCC Area API provide?
The service provides the /api/census/block/find endpoint to return Census block, county, and state FIPS codes, and /api/census/area to return FCC market areas for given coordinates.
What coordinate format is required by the FCC API?
Coordinates must be supplied as decimal degrees using standard WGS 84 latitude and longitude query parameters (e.g., latitude=38.883&longitude=-77.016).
Are there quotas or keys required for the FCC API?
No. The FCC Area API is open to the public without API keys or fees, though users should implement reasonable query caching and retry backoff.
