What is a Paytm UPI PIN?

A Paytm UPI PIN is a secure 4 to 6-digit numeric code used to authorize all bank transactions made through the Unified Payments Interface. You create this PIN when you first link your bank account to the app. It acts as a digital signature, ensuring that only you can approve payments or fund transfers. Key details include:

• It is required for every outgoing transaction and balance check.
• You must keep it confidential and never share it with anyone.
• It provides a vital layer of security for your linked bank accounts.
