CBP recently deployed changes to reject “UNKN” as a Standard Carrier Alpha Code (SCAC) for both AMS and non-AMS bill types in ACE cargo release.



When entering a non-AMS bill without a SCAC code, filers can bypass this validation with use of “ZZZZ” in the SCAC field in lieu of UNKN. Use of “ZZZZ” is a temporary feature and future programming will allow the field to be blank when manually entering a non-ABI entry with a non-AMS bill. Another CSMS will be issued when the temporary use of “ZZZZ” is discontinued. Please note that ZZZZ is not authorized for in use in manifest or in-bond transactions.
