Report Violations

Information from the public is vital to the work of the Antitrust Division. Your e-mails, letters, and phone calls could be our first alert to a possible violation of antitrust laws and may provide the initial evidence needed to begin an investigation.

To report antitrust concerns to the Antitrust Division:

If you do not think your concerns involve the antitrust laws, you may want to visit the Department of Justice site for more information or send a message to the Department of Justice.

Please keep in mind that the Antitrust Division is prohibited from giving legal advice to private individuals.

How We Handle Your Complaint

The Antitrust Division’s Citizen Complaint Center (CCC) handles complaints in the following way:

  1. The CCC creates a record of the information that you provided.
  2. The CCC conducts a preliminary review of your complaint for possible antitrust violations.
  3. If your complaint raises sufficient concern under the Federal antitrust laws, the CCC refers it to the appropriate Division legal staff where additional research may lead to a formal investigation into the reported conduct.
  4. If the Division needs more information, we will contact you typically within one month of submitting your complaint. Due to the confidential nature of Division investigations, you will not be notified if we open an investigation.

In some instances, the volume of mail, e-mail, and phone calls on a particular issue is so great that we cannot respond to each message individually. We would like you to know, however, that your views are important and all incoming correspondence is reviewed for possible antitrust violations.
