When initiating ACH Payments, it's possible to receive a Notification of Change (NOC) code as a return from the RDFI.
A NOC code is simply a notification that the payment order information is incorrect and must be corrected to ensure efficient processing. The payment order in question was still successfully processed, but it's a courtesy given by the bank, specifically the RDFI, to prevent future issues in transacting against this bank account.
In Modern Treasury, if you receive a NOC code, you will see a $0.00 Return object that contains the NOC code under Code
alongside the associated Reason
. Again, this is not a standard return and is rather the bank issuing a notification tied to a payment order - "we processed the payment, but some aspect of the account information has changed."
An example NOC you may receive in Modern Treasury.
MT currently handles NOC codes automatically with the change information provided in them. We adjust the external account to reflect those changes to proactively prevent future issues.
To see the account number and routing numbers attached to the original payment order, you can click the Payment Order link in the Return and navigate to the Counterparty Details tab.
Below is a useful resource outlining the common NOC codes you may receive:
