PostalPinCode API
PostalPinCode API is a free Indian postal code lookup service providing detailed information about post offices, delivery areas, districts, and states for any Indian PIN code (postal index number). The API returns comprehensive post office data including the post office name, branch type, delivery status, district, division, region, circle, and state name for a given 6-digit Indian postal code. Multiple post offices may be associated with the same PIN code in dense urban areas, and the API returns all matches. Access requires no registration or API key — the API is entirely public and free. Responses are returned as JSON arrays, with each element representing a post office associated with the searched PIN code. This makes it straightforward to integrate into Indian address validation forms, shipping calculators, or delivery coverage tools. For Nigerian developers, this API is not applicable. Nigeria's postal system is managed by NIPOST (Nigerian Postal Service) and uses a different addressing structure. There is no PIN code equivalent for Nigerian addresses in this database, and all queries for Nigerian postal contexts will return no results. This API should only be considered by Nigerian developers who are building applications that include Indian market functionality.
