Where is the UPI PIN number?

A UPI PIN is not a physical number found on a card or document; it is a 4 or 6-digit security code that you create yourself. You set this PIN during your initial registration on a UPI-enabled application. It acts as a digital password to authorize all money transfers and bank transactions. Since it is a confidential number chosen by you for security, it is never displayed openly within any app. If you forget it, you must reset it using your debit card details.
