You can use this table to build CELEX numbers. The Celex number is the unique identifier of each document in EUR-Lex, regardless of language. Read more about Celex numbers on our Help pages.

All documents (except from sectors 0 and 7) may have one or more corrigenda. A corrigendum has the same Celex number as the original act, with a suffix "R(xx)", where "xx" is the sequential number of the corrigendum.
