US Zip Code API

The US Zip Code API v2 delivers fast, reliable access to United States ZIP code data through a developer-friendly REST API. Retrieve ZIP code details, validate ZIP codes, search by city or state, calculate distances, and perform radius searches using any of our available endpoints.

Unlike basic ZIP code APIs that rely only on USPS data, this API integrates multiple authoritative datasets to provide enriched geographic, demographic, and economic insights—allowing developers to access powerful location intelligence from a single unified API.
