CELEX number

A CELEX number is the unique document identifier EUR-Lex assigns to every EU legal document, encoding its sector, year, document type and sequence number.

The GDPR is 32016R0679: sector 3 (legislation), year 2016, type R (regulation), number 0679. The Schrems II judgment is 62018CJ0311: sector 6 (case law), year 2018, CJ (Court of Justice judgment), case number 311.

Consolidated versions add a 0 sector prefix and a date suffix, for example 02016R0679-20160504. Corrigenda add R(01), R(02) and so on.

Arieta Data uses the CELEX number as the record id for every EU document, so records join cleanly with EUR-Lex, Cellar and LexAPI.
