If you wish to export goods from the customs territory of the Union to a third country, you must, under certain conditions, declare this in advance via the "Automated Tariff and Local Customs Clearance System" (ATLAS). Your declaration is received automatically and stored under a consignment-related reference number (Master Reference Number, MRN). When the (re-)export declaration is accepted, you will be notified of the MRN. In addition, when the goods are released for the (re-)export procedure, you will receive an export accompanying document (ABD) on which, among other things, the MRN is noted. You can use the Internet status information to call up general information on (re-)export transactions online. In order to prove your eligibility, you must identify yourself with your EU-wide registration and identification number for economic operators (EORI number) or your identification number from a third country (TCUI number) identify yourself.
