Identifying and handling HMRC error codes (easy mode)

You have received an error code from HMRC and want to modify your declaration for resending? Here you will learn how to proceed:

Proceed as follows if you encounter HMRC customs errors

Please note: This is an error coming from HMRC regarding the information submitted to customs, not an error generated from the AEB solution.

1. Research the error code via HMRC’s website:  CHIEF error codes - GOV.UK. 
2. Once you have located your error message, modify your declaration with the correct information and resend it to the authorities.
3. If you follow the advice and still receive a further error message you may need to raise a request with HMRC as to why they are rejecting your declaration data submission. Is this the case, raise a request with HMRC: chief.operations@hmrc.gsi.gov.uk
