How to block a UPI number?

To block a UPI number or deactivate UPI services, you can follow these steps:

• Contact your bank's customer care immediately to request a temporary or permanent block on your UPI services.
• If your phone is lost, block your SIM card through your telecom provider to prevent unauthorized access via OTP.
• Use the official NPCI helpline or your bank's mobile app or net banking portal to disable UPI account access.
• Alternatively, use your payment app settings to deregister or unlink your bank account.
