How this service works
Resolve a postal/ZIP code to its place name(s), administrative divisions, and coordinates. Pass `postalCode` and a 2-letter `country` (default US). Returns each matching locality: place, admin1 (state/province name + code), admin2 (county/district), and lat/lon. International — covers major markets (US, GB, CA, DE, FR, AU, NL, ES, IT, CH, SE, MX). Use it to normalize and enrich addresses, derive the state/county for a ZIP, or geolocate a postal code in an ETL pipeline.
Output
Returns one or more matching localities for the postal code, each with: place name, admin1 (state or province name and code), admin2 (county or district), and latitude/longitude coordinates. International coverage includes US, GB, CA, DE, FR, AU, NL, ES, IT, CH, SE, and MX.
Example use cases
Example prompt
“What city, state, and county does ZIP code 94103 correspond to in the US — and can you give me its coordinates too?”
Technical details
Endpoint
GEThttps://2s.io/api/geo/postalWhen to prefer
Use this endpoint when you need to resolve or enrich a postal/ZIP code with human-readable place names, state/province codes, county information, or geographic coordinates. Ideal for ETL pipelines, address normalization, deriving state from ZIP without a full geocoding stack, or geolocating users from a postal code. Covers major international markets beyond just the US.
Side effects
- Unknown or invalid postal code returns empty results or 404
- Unsupported country code returns an error or empty response
- Missing required postalCode parameter returns a 400 bad request
- Some postal codes map to multiple localities, returning an array
- Non-numeric or malformed ZIP codes may return no match
