Notice of Return (NOR)

Overview

A Notice of Return (NOR) is a formal notification sent by a receiving financial institution to the originating financial institution when an ACH (Automated Clearing House) transaction cannot be processed successfully. This mechanism is a critical component of the ACH network's risk management system, providing timely feedback about failed transactions.

NOR Process Flow

Return Timeline

  • Standard ACH Returns: Must be initiated by the RDFI within 2 banking days of settlement date
  • Notification: Merchants typically receive NOR notifications within 3-5 business days after initial transaction processing

  2. Additional Processing Fees: Many financial institutions charge fees for returned ACH transactions

System Handling

When a Notice of Return is received for a transaction:

  1. The payment status is automatically updated to reflect the failure
  2. The associated payment method is designated as an Invalidated Payment Method for certain return codes.
  3. System notifications are generated for both internal teams and the merchant
  4. The return reason is logged for reporting and analytics purposes
