European Unique Identifier

☆ Save On Wikipedia ↗

The European Unique Identifier (EUID) is a standardized identification number for companies operating in the European Economic Area.[1] The EUID is issued by the national business registers based on information provided during company registration.

The European Parliament adopted Directive 2012/17/EU on 13 June 2012 with the aim of setting up a system for connecting national business registers with each other.[2]

The EUID is part of the Business Registers Interconnection System (BRIS), set up in line with Directive 2012/17/EU and Commission Implementing Regulation (EU) 2015/884.[3]

Structure

The structure of the EUID is compliant with ISO 6523. It contains a country code (ISO 3166-1 alpha-2, except for Greece, which uses EL), register identifier, registration number and optionally a verification digit.[4][5]
