NOC Reference Guide

A Notification of Change (NOC) is a non-dollar entry transmitted by a Receiving Depository Financial Institution (RDFI) to notify you that information contained within an entry is erroneous and/or has become outdated and must be changed.

The ACH Rules require your company to make the requested changes within 6 banking days of the receipt of the NOC or prior to the initiation of another ACH entry. Notification of changes will be sent to all ACH users via secure email.
