Api Endpoint

2s

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.
