What is the UPI PIN number in Paytm?

A UPI PIN (Unified Payments Interface Personal Identification Number) in Paytm is a secure 4 or 6-digit numeric code created during registration. It acts as a password to authorize every transaction, such as money transfers or bill payments, directly from your linked bank account. This PIN is set by the user and is essential for maintaining transaction security. To ensure the safety of your funds, you should keep your UPI PIN confidential and never share it with anyone.
