Its staff of policy specialists, lobbyists and lawyers make up the world's largest nonprofit business federation. The chamber has grown to represent more than 3 million businesses, nearly 3,000 state and local chambers, 830 associations, and more than 90 American chambers of commerce abroad. Its members include businesses of all sizes and sectors, from large Fortune 500 companies to home-based, one-person operations.

In 1912 United States President William Taft's vision became a reality when a group of 700 delegates from various commercial and trade organizations came together to create a unified body of business interest that today is the U.S. Chamber of Commerce.
