Nacha voting members approved five Nacha Operating Rules changes aimed at increasing the awareness and efficiency of International ACH Transactions, or IATs.

The existing Nacha Rules for IATs became effective in 2009, replacing previous cross-border ACH payments with a new transaction rule set and format that enabled compliance with the Travel Rule and Office of Foreign Assets Control (OFAC) sanction programs. Approximately 121 million IATs were made in 2024.

One of the approved Rules refines the definition of an IAT with the goal of making it easier for ACH Originators and Originating Depository Financial Institutions (ODFIs) to determine whether a payment should be classified as an IAT.

The other approved Rules are aimed at transaction and data efficiency. They include adding the capability to carry a person’s date of birth for sanctions screening; adding a new return reason to indicate an issue with sanctions screening as distinct from other return reasons; recognizing the possibility that the financial agency outside the U.S. is a non-traditional account-holding institution or organization; and requiring U.S. financial institutions to register IAT-specific contacts in Nacha’s ACH Contact Registry.
