What is a BHIM UPI number?

A BHIM UPI number is a unique identifier, such as your mobile number, used to send or receive money instantly between bank accounts via the Unified Payments Interface. It acts as a virtual address, eliminating the need to share sensitive bank details like account numbers or IFSC codes. During registration on the BHIM app, a default ID is created using your mobile number, which can then be used for secure, real-time transactions 24/7.
