CSMS # 70162211 - ACE Portal: Addition of Verification Step for ACH Refund Changes – Coming October 10

Beginning October 10, 2026, U.S. Customs and Border Protection (CBP) will require email or short message service (SMS) verification for Automated Clearinghouse (ACH) refund information changes made in the Automated Commercial Environment Secure Data Portal (ACE Portal). Following this update, authorized ACE Portal users will receive a security token via email, with the option to also receive it via SMS message, when attempting to add or modify ACH refund information within an ACE Portal importer sub-account. Security token verification will be required to successfully complete the ACH information change. In addition, other authorized users under the applicable importer sub-account will have the option to enable notifications and receive email or SMS message alerts following any ACH refund information changes. 

Following last month’s addition of SMS as an ACE Portal login authentication method, this additional verification step enhances ACE Portal security while maximizing flexibility for users. Detailed instructions on how to manage ACH refund information and associated email and SMS information for verification in the ACE Portal will be included in an upcoming update to the ACE Portal: ACH Bank Information for Electronic Refunds training guide.
