Make Sense of International ACH Transactions

Overview Icon

International ACH Transactions are more common every year, so it’s critical that your financial institution stays up-to-date on secure and efficient IAT processing. Over the past few years, NACHA has updated the NACHA Operating Rules to reflect the increasing number of cross-border transfers. We’ve incorporated information on all parties to the transaction in the international payment format, required foreign payments to be classified with the IAT designation, and clarified how IATs with split transactions should be handled.
