How to set up UPI on Paytm?

To set up UPI on Paytm, open the app and tap your profile icon. Navigate to UPI and Payment Settings and select Add Bank Account. Choose your bank from the list; the app will verify your mobile number via SMS. Once your account is linked, you will need to set a UPI PIN using your debit card details (last six digits and expiry date). If you already have a UPI PIN for that bank, you can use the same one. Once verified, your UPI ID is ready for transactions.
