Additional Information on the Company Identification Field and Company Batch Header Field information:

Issue: The originator included inconsistent or no information in the Company Identification Field in the Company Batch Control Record (#8 Record) and it does not match the Company Identification Field in the Company Batch Header Record (#5 Record).

The Nacha Operating Rules (Off-site) identify the Company Identification (Field position 45-54) in the Company Batch Control Record as a Required Field; this Field carries the same information as the Mandatory Company Identification Field(Field positions 41-50) of the Company Batch Header Record.

What action is required?

The originator should ensure the Company Identification Field carries the same information in the Company Batch Header Record and Company Batch Control Record to prevent potential processing delays and/or returns from the RDFI due to their inability to process the item(s).

Why wasn’t this a problem in the past?

The previous FedACH platform copied the data in the Company Identification Field of the Batch Header Record to the Company Identification Field in the Batch Control Record to synchronize the two Fields. The new FedACH platform does not perform this copy step to synchronize the two Fields.

The Federal Reserve as an ACH operator performs compliance edits on Mandatory Fields, but is not required to perform them on Required Fields.


Mandatory Field not meeting the NACHA data specifications will cause the ACH Operator to pend or reject files, batches, or entries. A file or, batch placed in a pending status by the ACH Operator will await action to be released or rejected based on instructions provided by the Sending Point.

The omission of a Required Field will not cause a file, batch, or entry to reject at the ACH Operator, but may cause a reject at the RDFI and may result in the return of the entry or entries.
