ACE Portal Modernization - Phase 3

Note: Internet browser bookmarks should be updated to reflect the modernized portal URL: If trade users are using Internet Explorer, access to modernized ACE Portal functionality may be limited. Alternatively, Microsoft Edge or Google Chrome enable access to all features.

In January 2023, U.S. Customs and Border Protection (CBP) began gradually deploying Phase 3 of the Automated Commercial Environment (ACE) Portal Modernization. This deployment phase was completed on May 21. Phase 3 changes included updates to the References tab and the migration of other functionality from the legacy ACE Portal to the modernized platform.

What changes will trade, and partner government agency (PGA) users see in the modernized ACE Portal?

  • The following ACE application links are included in Phase 3 of the ACE Portal modernization:
