How to Handle Notifications of Change (NOCs)
A notification of change (NOC) occurs when the bank sending funds notifies the bank receiving funds that some portion of the once-valid information has changed. This could result from a bank buying another bank, which would cause routing numbers to change. With NOCs, ACH transactions will run successfully, but your business will incur a fee. These notifications of change are inevitable, but they could eat away at your profits if you’re not with the right provider.
