How this service works
Geocode one US street address with the U.S. Census Bureau: standardised address, lat/lon, state, county, census tract, block group, ZCTA, metro area, congressional district (official GEOIDs). No match = not charged.
Output
Returns a standardized US address, latitude and longitude coordinates, FIPS state and county codes, census tract ID, block group, ZCTA (ZIP Code Tabulation Area), metro area (CBSA), and congressional district — all as official GEOIDs from the U.S. Census Bureau. If no match is found, the call is not charged.
Example use cases
Enrich customer records with census data
“I have a customer address — 1600 Pennsylvania Ave NW, Washington, DC 20500 — can you look it up and tell me the census tract, block group, and ZCTA so I can append that to their record?”
Verify congressional district for voter app
“For the address 123 Main St, Springfield, IL 62701, can you find the official congressional district GEOID and county FIPS code from the Census Bureau?”
Map property to metro area and county
“Can you geocode 800 N Michigan Ave, Chicago, IL 60611 and return the lat/lon, county name, and metro area so I can categorize it in our property database?”

Endpoint
GEThttps://gogeta2-u35175.vm.elestio.app/agents/v1/geo/us-address?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need authoritative, government-sourced geocoding with official Census GEOIDs (tract, block group, ZCTA, congressional district, FIPS codes) rather than just lat/lon from a commercial provider. Ideal for compliance, demographic analysis, political redistricting, or any use case requiring Census-aligned geographic identifiers. The no-match-no-charge pricing makes it low-risk for batch validation workflows.
Side effects
- No address match found (no charge): address too ambiguous, incomplete, or not in Census database
- Malformed address string: missing house number or unrecognizable format returns an error
- Non-US address: endpoint only handles US addresses, international addresses will not match
- Rate limiting or upstream Census API downtime may cause timeouts or errors
