How do I register my UPI ID?

To register your UPI ID, first download a UPI mobile payment application, such as Paytm, on your smartphone. Open the app and complete the registration by entering your mobile number and verifying it with an OTP. Next, link your bank account by selecting it from the provided list. Ensure the mobile number matches the one registered with your bank. Finally, if it is your first time linking the bank, you will be prompted to create a UPI PIN using your debit card details.
