How this service works
Zip and postal code lookup: place names, state and coordinates for 60+ countries. Input: 'US 90210' or 'DE 10115'.
Output
Returns a JSON object with the country name, postal code, and a list of matching places — each with a place name, state/region, latitude, and longitude. The source is attributed to Zippopotam.us.
Example use cases
Enrich order data with city info
“I have a US ZIP code 10001 from a customer order — can you tell me what city and state that corresponds to, and give me the lat/lon too?”
Verify international postal code location
“What place does German postal code 10115 belong to, and what are its coordinates?”
Geolocate user-submitted postal code
“A user signed up with postal code SW1A 1AA in the UK — can you look up what city and region that maps to, along with the latitude and longitude?”
Technical details
Endpoint
POSThttps://minty-sprout.onrender.com/v1/postal-code?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need lightweight postal-code-to-location resolution (city, state, coordinates) for 60+ countries without requiring a full geocoding pipeline. It is ideal for address enrichment, form validation, and geolocation from ZIP/postal codes when you already have the country code. Prefer a full geocoding API if you need street-level address parsing or reverse geocoding from coordinates.
Side effects
- Invalid or non-existent postal code returns empty places array
- Unsupported country code may yield no results
- Malformed input (missing country or code) may return an error
- Network timeout on Render.com cold start for infrequently called endpoints
