U.S. Department of Justice Contacts

The U.S. Department of Justice’s (DOJ) Antitrust Division has a mission to promote and protect the competitiveness process — and the American economy — through the enforcement of antitrust laws. The antitrust laws apply to virtually all industries and to every level of business, including manufacturing, transportation, distribution, and marketing. They prohibit a variety of practices that restrain trade, such as price-fixing conspiracies, corporate mergers likely to reduce the competitive vigor of particular markets, and predatory acts designed to achieve or maintain monopoly power. The DOJ Antitrust Division is committed to ensuring that its essential efforts to preserve competition for the benefit of businesses and consumers do not impose unnecessary costs on American businesses and consumers.
