The Chamber of Commerce of the United States of America (USCC) was founded in 1915 in Washington, D.C. USA. USCC is the world’s largest business federation representing more than 3 million businesses of all sizes, sectors, and regions. It includes hundreds of associations, thousands of local chambers, and more than 104 American Chambers of Commerce in 91 countries. Its core mission is to fight for business and free enterprise before Congress, the White House, regulatory agencies, the courts, the court of public opinion, and governments around the world. From its headquarters near the White House, the Chamber maintains a professional staff of more than 300 of the nation’s top policy experts, lobbyists, lawyers, and communicators. The Washington staff is supported by eight regional offices around the country; an office in Brussels; an on-the-ground presence in China; and a network of grassroots business activists. Members include businesses of all sizes and sectors-from large Fortune 500 companies to home-based, one person operations. In fact, 96% of the membership are companies with fewer than 100 employees.
