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

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
