What is the UPI code?

A UPI code, commonly known as a UPI PIN (Personal Identification Number), is a self-selected 4 or 6-digit secret numeric password. It is essential for authorizing every fund transfer and payment made through the Unified Payments Interface platform. This security code ensures that only the account holder can initiate transactions from their linked bank account. For safety, this code should never be shared with anyone, as no official or bank representative will ever ask for it to process a payment.
