Overview

PostalPinCode is a free public API that returns postal and address details for any Indian PIN code. You can look up district, state, and post office information by simply providing a 6-digit PIN code. It requires no authentication, making it the easiest way to add India address lookup to any application.

Beginner Tip

The API returns an array of post offices for each PIN code since a single PIN code can serve multiple post offices. Always loop through the PostOffice array to display all matching locations rather than just reading the first result.

Common Errors & Troubleshooting

Generated guidance based on this API's documentation, not observed by us. Treat it as a starting point and check against the provider's own error reference.

Empty PostOffice array The PIN code is valid in format but does not exist in the database
Verify the 6-digit PIN code is correct; use India Post's official site to cross-check before querying
Status "Error" in response Sending less than 6 digits or non-numeric characters as the PIN code
Always validate that the PIN code is exactly 6 numeric digits before making the API call
Unexpected array wrapper The response is wrapped in an outer array, which trips up many JSON parsers
Parse the response as an array and access response[0].PostOffice to get the list of post offices
