Pin Code Verification
Verify any Indian PIN code and resolve it into area, city, district and state details.
What is the Pin Code Verification?
The BILAPI Pincode Verification API validates any Indian 6-digit PIN code and resolves it into the area, city, district, state and post-office details it belongs to — perfect for validating shipping and KYC addresses and auto-filling address forms.
E-commerce, logistics, lending and onboarding platforms use it to confirm a PIN code is real, auto-populate city and state from the PIN, and reduce address-entry errors and failed deliveries.
Send a 6-digit PIN code and receive the full area details as JSON in milliseconds.

area | Area / locality name(s) for the PIN. |
