Tips on How to Resolve AES Fatal Errors

When a shipment is filed to the AES, a system response message is generated and indicates whether the shipment has been accepted or rejected.  If the shipment is accepted, the AES filer receives an Internal Transaction Number (ITN) as confirmation.  However, if the shipment is rejected, a Fatal Error notification is received. 


To help you resolve AES Fatal Errors, here are some tips on how to correct the most frequent errors that were generated in AES for this month.

Fatal Error Response Code:  111

Narrative: U.S. State of Origin Code Must Be “PR”

Reason: The U.S. State of Origin Code reported was not “PR” (Puerto Rico) and the Country of Ultimate Destination Code reported was “US” (United States). 

Resolution: The U.S. State of Origin Code must be "PR" for shipments exported from Puerto Rico to the United States.

Verify the U.S. State of Origin Code and the Country of Ultimate Destination Code, correct the shipment and resubmit. 


Fatal Error Response Code:  123

Narrative: Conveyance Name Missing

Reason: The Conveyance Name/ Carrier Name is missing and the Mode of Transportation reported is one that requires the Conveyance Name/ Carrier Name to be reported.

Resolution: The Conveyance Name / Carrier Name must be reported for Vessel, Air, Rail, and Truck shipments. For Vessel shipments, report the name of the vessel. For Air, Rail, and Truck shipments, report the name of the carrier.

Verify the Mode of Transportation Code and Conveyance Name / Carrier Name, correct the shipment and resubmit.

For a complete list of Fatal Error Response Codes, their reasons, and resolutions, see Appendix A – Commodity Filing Response Messages.


It is important that AES filers correct Fatal Errors as soon as they are received in order to comply with the Foreign Trade Regulations.  These errors must be corrected prior to export for shipments filed predeparture and as soon as possible for shipments filed postdeparture but not later than five calendar days after departure.
