What is my UPI ID PIN?

Your UPI PIN, or Unified Payments Interface Personal Identification Number, is a secure 4 or 6-digit code. It is created when you register for UPI and is required to confirm every transaction to prevent fraud. It is private and should never be shared. If you forget your UPI PIN, you can reset it by logging into your application, such as Paytm, and selecting the 'Forgot UPI PIN' option after providing some details.
