PostalCodes integrations

Connect PostalCodes to any other app, or use it from your AI client over MCP. PostalCodes is a reference database of postal codes and the places they cover. Callers can search a postal code within a country to retrieve its city, state or province, county and coordinates, search the reverse direction by place name, list the countries covered and download their postal code exports, and validate that an address's postal code matches the locality supplied with it. No credentials required.
