What is the RRN number in a UPI transaction?

The RRN (Retrieval Reference Number) is a unique 12-digit numeric identifier assigned to every UPI transaction. Generated by the bank or payment service provider, it serves as a critical tracking ID for identifying individual payments within the banking system. Its primary uses include:

• Tracking the real-time status of a payment.
• Resolving disputes or complaints regarding failed or pending transactions.
• Verifying transaction details for refunds.
• Providing a reference for banks to reconcile digital payments accurately.

You can find the RRN in your app's transaction history, often labeled as the UPI Ref No.
