In a Cargo Systems Messaging Service (CSMS) bulletin published on May 1, 2026, U.S. Customs and Border Protection (CBP) wanted to remind the trade that the trade account owners can self-manage user reactivations in the Automated Commercial Environment Secure Data Portal (ACE Portal).
Trade account owners and proxy trade account owners can do the following to reactivate their account users:
- Log into the ACE Portal as the trade account owner.
- Select the “tools” tabs.
- Select the name of the user you want to reactivate.
- Click the “reactivate” button
- Have the reactivated user confirm access by logging into the ACE Porta.
CSMS # 68510928 and a link to a more in depth guide on ACE user management can be found here:
