How to contact DG Competition for Antitrust, Cartels and general issues

In its efforts "towards the e-Commission", the European Commission encourages the use of electronic communication. Correspondents in antitrust and cartel cases are asked to submit documents as electronic files, and preferably by electronic means.

Electronic submissions:

Please follow the Recommendations for Electronic Document Submissions in Antitrust and Cartel Case Proceedings.

If you want to send paper documents, please respect the following rules :

  • No bound documents, stapled documents, no cardboard dividers, no double-sided pages
  • Format: only A4 weighing less than 120 gr/m2

The Registry reserves the right to request electronic copies for voluminous paper documents.

In all your correspondence, please specify the name of the case and the case number.

All correspondence relating to a case must be sent to the Registry, even when addressed to a specific Directorate or Unit within DG Competition.
