Numbering of acts

The numbering of acts varies according to the type of act and year of publication.

Acts of the L series of the Official Journal

With the exception of international agreements and corrigenda, all acts and other texts receive a number. This number is unique and is either part of the title or placed at the end of the title in square brackets. It also represents the number of the Official Journal in which the act or other text is published.

The number of an act is made up of three parts.

• Domain abbreviation in brackets

  Abbreviation	Description
  (EU)	European Union
  (Euratom)	European Atomic Energy Community
  (EU, Euratom)	European Union and the European Atomic Energy Community
  (CFSP)	common foreign and security policy

• Year of publication: four digits
• Sequential number: This number is based on a yearly sequence and comprises as many digits as necessary.

NB: For certain acts, the number assigned by the Publications Office does not include a domain and is placed in square brackets at the end of the title. This number is not considered to be part of the title and is not cited in references to the act in question.

Please consult the Interinstitutional Style Guide​​ for more information on the numbering of acts published in the L series over time, dual numbering, unnumbered acts and other texts, etc.

Documents of the C series of the Official Journal

With the exception of corrigenda, documents published in the C series are assigned a notice number that consists of:

• the letter ‘C’ corresponding to the C series;
• the year of publication, comprising four digits;
• the sequential number, based on a yearly sequence and comprising as many digits as necessary.

The notice number is identical to the Official Journal number that appears in the header of the Official Journal.

Please consult the Interinstitutional Style Guide​​ for more information on the numbering of documents published in the C series over time, special numbering, unnumbered acts and other texts, etc.
