This ACH return code indicates that the unique 15-digit trace number used to track and reconcile your transaction is either missing from required addenda records or doesn't match between related transaction components. Trace numbers are assigned by the ODFI and consist of 8 digits representing the routing number and 7 digits for the sequence number, serving as essential identifiers for transaction tracking.
Error message: "(1) Original Entry trace number is not present in the Addenda Record on an automated return or Notification of Change entry; or (2) Trace number of an Addenda Record is not the same as the Trace Number of the preceding Entry Detail Record."
What Causes ACH Return Code R27?
The R27 ACH return code means "Trace Number Error" and indicates that the unique tracking number assigned to your ACH transaction is either missing from required records or doesn't match between related transaction components. Every ACH transaction receives a 15-digit trace number from the ODFI that serves as a critical identifier for tracking, reconciliation, and dispute resolution purposes.
R27 occurs in two specific scenarios: when the original entry trace number is missing from addenda records during returns or notifications of change, or when trace numbers don't match between addenda records and their corresponding entry detail records. This tracking system ensures transaction integrity and proper record-keeping throughout the ACH network, making accurate trace numbers essential for successful processing.
Can You Retry R27 Payments?
You can retry R27 payments after correcting the trace number issues. Add missing trace numbers to addenda records or ensure trace numbers match between all related transaction components before resubmitting the payment.
How to Respond to an R27 Code
An R27 return requires identifying and correcting the specific trace number issue before resubmitting the transaction.
