How this service works
US street address to coordinates plus matched/normalized address. Source: US Census Bureau geocoder. JSON.
Output
Returns a JSON object containing the geographic coordinates (latitude and longitude) of the matched address along with the normalized/matched address string as parsed and confirmed by the US Census Bureau geocoder. Useful for mapping, routing, and address standardization workflows.
Example use cases
Map pin drop from address
“I have a customer address — 350 Fifth Avenue, New York, NY 10118 — can you get me the exact latitude and longitude so I can drop a pin on a map?”
Normalize messy address data
“I've got this address that might be slightly off: '742 Evergreen Terr, Springfield IL 62704' — can you run it through the Census geocoder and tell me the corrected, normalized version along with coordinates?”
Distance calculation setup
“Before I calculate driving distances, I need coordinates for both my warehouse at 4600 Silver Hill Rd, Suitland MD 20746 and the delivery address at 200 E Colfax Ave, Denver CO 80203 — can you geocode both?”
Technical details
Endpoint
GEThttps://polyform.polyform-org.workers.dev/v1/geo/geocodeWhen to prefer
Choose this endpoint when you need authoritative, government-sourced geocoding of US street addresses with normalized address output. It is ideal for applications requiring Census-grade accuracy, address standardization alongside coordinate lookup, or when you want a cost-effective ($0.002/call) geocoding option that doesn't require a Google Maps or similar commercial API key. Prefer this over commercial geocoders when US-only coverage is acceptable and Census Bureau authority is valued.
Side effects
- Address not found or unmatched by Census geocoder — returns no result or empty match
- Non-US addresses are not supported; international addresses will fail or return no match
- Ambiguous or incomplete addresses may return a low-confidence or wrong match
- Malformed input query may return a 400 error
- Service downtime or upstream Census Bureau API unavailability causing 5xx errors
