CSMS # 70362316 - ACE Portal Application Updated to Include Account Merger Requests

On November 5, 2026, U.S. Customs and Border Protection updated the Automated Commercial Environment Secure Data Portal (ACE Portal) account application to facilitate merger requests for two or more ACE Portal accounts under a single top account. Going forward, if one or more entities need to merge ACE Portal accounts, the account owner for the acquiring entity’s account should use the automated ACE Portal application to request the merger.

As part of an account merger request, requestors will be required to upload a letter, on company letterhead, signed by an authorized company official, that includes the following information:

• The company name(s) and applicable account identifiers for both the acquiring entity and the newly acquired entity(ies)
• Subsidiary acquisition date
• Current contact information, including telephone number and email address

Requestors will also have the option to upload any other applicable background documentation (e.g., bond information).
