Refused Notification of Change code

C68 refused NOC code: DFI Account Number Not From Original Entry Detail Record

An ODFI sends C68 back to the RDFI to refuse a Notification of Change: dfi account number not from original entry detail record.

What C68 means

C68 is the refused NOC code DFI Account Number Not From Original Entry Detail Record. A refused NOC tells the RDFI that its Notification of Change was itself wrong, so the ODFI and the Originator will not act on it.

  • The DFI account number in the NOC is not the one from the original entry detail record.
Confirm the refused-NOC timeframe in the current Nacha Operating Rules.

What happens next

The refused NOC goes back to the RDFI, which can correct the Notification of Change and send it again. Until a correct NOC arrives, nothing changes in the Originator’s records.

The ODFI may refuse a NOC within 15 days of receiving it.

How C68 appears in a NACHA file

A refused NOC travels like a NOC: a zero-dollar entry in a batch with SEC code COR and an addenda record of type 98. The refused code sits in positions 4–6, followed by the original trace number and details copied from the NOC being refused; the Rules give its layout field by field.

To read a NOC file record by record, open the file in NACHA Navigator, a free sister site that parses NACHA files in your browser without uploading them.
