Where is the UPI PIN located?

A UPI PIN is not physically located on your bank card or in any document; it is a confidential 4 or 6-digit number that you create yourself during the initial registration of your bank account on a UPI-enabled application. This PIN is stored securely within the banking system and is known only to you. You must enter it manually to authorize every transaction or to check your account balance. If forgotten, you can reset it using your debit card or Aadhaar details within your payment app.
