How this service works
The 15-digit census block FIPS code containing a US coordinate, with its county and state codes and the block bounding box.
Output
Returns the 15-digit census block FIPS code (state + county + tract + block), the 2-digit state FIPS code, the 5-digit county FIPS code, and the geographic bounding box (min/max lat/lon) of the census block containing the queried coordinate.
Example use cases
Regulatory compliance geofencing check
“I need to know which census block the property at lat 40.7128, lon -74.0060 falls in — including the county and state FIPS codes — for a regulatory filing.”
Demographic data enrichment pipeline
“For each of our store locations, starting with the one at latitude 33.7490 and longitude -84.3880, can you pull the census block FIPS code so I can join it to ACS demographic data?”
Disaster relief zone verification
“We have a reported incident at coordinates 29.9511 latitude and -90.0715 longitude — can you tell me the exact census block, county, and state codes so I can check if it falls within a declared disaster zone?”
Technical details
Endpoint
GEThttps://fittings.sh/v1/fcc/census-blockWhen to prefer
Use this endpoint when you need authoritative FCC/Census-sourced census block FIPS codes for US coordinates, especially when you require the full 15-digit code with county and state breakdowns and the block bounding box. Prefer this over general geocoding APIs when the specific output needed is census geography identifiers rather than street addresses or place names.
Side effects
- Coordinate outside the US returns no match or an error
- Missing lat or lon parameter returns a 400/validation error
- Invalid numeric values for lat/lon cause a schema validation failure
- Coordinate falls in a water body or offshore area with no census block assignment
