The National Payments Corporation of India (NPCI) has instructed third-party UPI apps and banks to deactivate inactive UPI IDs and numbers that have been unused for over a year. This is to prevent accidental money transfers to unintended recipients when customers change their mobile numbers without unlinking their old numbers from the banking system. The NPCI has set a deadline of December 31, 2023, for implementation of these guidelines. UPI apps are also required to perform Requester Validation before initiating transactions and display the customer’s name fetched from the banking system.
