The European Union has created a registration system for identification of foreign trade or logistics operators in connection with customs clearance. The identification is based on the EORI number.

EORI number means: a number, unique in the European Community, assigned by a Member State customs authority or designated authority or authorities to economic operators and to other persons in accordance with the rules laid down in Part I, Title I, Chapter 6 CCIP. In Finland, the EORI number is assigned by Customs. When registering for customs purposes in one Member State, an operator is assigned an EORI number, which shall be used in all Member States, when necessary, in connection with customs clearance.
