To register a UPI PIN, link your bank account to a UPI-enabled app and follow these steps:
- Navigate to the bank accounts section and select the account to set the PIN.
- Enter the last six digits and expiry date of your debit card.
- Verify your identity using the OTP sent to your registered mobile number.
- Enter a new 4 or 6-digit UPI PIN and confirm it to complete the registration.
Alternatively, some banks allow registration using Aadhaar-based verification if your mobile number is linked to both Aadhaar and your bank account.
