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.
