How this service works
Places for a postal or ZIP code in about 60 countries: place names, state or region and coordinates. Use to validate addresses, fill forms or locate customers.
Output
Returns one or more places matching the postal code, including place name(s), state or region name, and geographic coordinates (latitude/longitude) for the given country and code combination.
Example use cases
Autofill city from ZIP at checkout
“A customer just entered ZIP code 90210 in the US on our checkout form — can you fill in the city and state for them automatically?”
Validate and locate international customer
“We have a customer who says they're in Canada with postal code M5H 2N2 — can you confirm what city and region that is and get the coordinates?”
Map customer locations by postcode
“I have a list of UK postcodes and I need to know the place name and coordinates for EC1A 1BB so I can plot it on a map.”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/geo/postcode?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need lightweight postal-code-to-location resolution without a full geocoding pipeline — ideal for address validation, form autofill, or customer location enrichment across ~60 countries at very low cost per call.
Side effects
- Invalid or unknown postal code returns empty results or error
- Unsupported country code returns an error or no data
- Malformed ISO country code causes a validation error
- Some countries have incomplete postal code coverage, returning partial or no results
