What is a UPI ID number?

A UPI ID is a unique identifier, also known as a Virtual Payment Address (VPA), that is linked to your bank account for conducting Unified Payments Interface (UPI) transactions. It allows you to instantly send and receive money via UPI apps without needing to share your sensitive bank details. It generally follows the format "name@bank" and acts as a unique identity for the user. For instance, in a UPI app like Paytm, you can find your UPI ID in the account settings.
