Your T1 declaration has been rejected with the message:
- FTX+ACD+++Authorisation details invalid”
A valid EORI number has not been used in the addresses tab in the declaration under "TIN". This is a licence for authorised consignees.
You need to apply for the licence or you must use a valid EORI number that does have a licence. The field is not mandatory, you can leave it blank.
When a customer uses new licences, it may be the case that Customs in Heerlen has forgotten to link the authorised locations to the licences. This also causes this error message. The customer needs to contact Customs in this situation.
