Notification of Change


Notification of Change (NOC) is used to change and/or correct account information for federal government transactions processed through the Automated Clearing House (ACH).

Although the federal government basically follows Nacha Operating Rules for NOCs, some of the data requirements for Federal government NOCs are not the same as those for commercial NOCs.

The procedures contained in this chapter apply only to federal government NOCs.
