The customs registration identifier assigned after registration for customs purposes under the UCC framework used by CBAM.
EORI number is an operator-identity value for customs workflows, not a general company identifier. It identifies the economic operator in customs systems, but it does not by itself prove importer status, CBAM authorisation, representation authority, or emissions compliance.
CBAM defines the EORI number by reference to registration for customs purposes under Union Customs Code Article 9. Article 9 is the registration framework, not a neat standalone short definition of EORI; CBAM supplies the definitional wording for this page.
Regulation (EU) 2023/956 establishing a carbon border adjustment mechanism
the number assigned by the customs authority when the registration for customs purposes has been carried out in accordance with Article 9 of Regulation (EU) No 952/2013;
Reference: Article 3, point 20
Regulation (EU) No 952/2013 laying down the Union Customs Code
Economic operators established in the customs territory of the Union shall register with the customs authorities responsible for the place where they are established.
Contextual upstream registration anchor for the EORI concept; useful because CBAM points to Article 9, even though Article 9 is not itself a short standalone EORI-number definition.

Reviewed public draft page. Aligns with CBAM/customs actor-boundary policy: separates authority routing, declaration responsibility, customs territory, EORI identity, facility boundaries, and production-process evidence.
Economic Operators Registration and Identification number (EORI number) is the EU customs identity number used to identify economic operators in customs interactions and declarations.
Implementation records should capture EORI value, economic operator record, declaration link, validation status, issuing Member State, actor role, representation basis, goods-line relationship, CBAM declarant link where relevant, and validity period or update date.
EORI number is the operator-identity key that lets customs declarations, importer records, representatives, and CBAM actor records be joined. It should be validated and linked to role-specific evidence rather than treated as proof of every obligation attached to an import.
