About Us
Representing your ideas—and interests—in Washington for nearly a century.

Whether you own a business, represent one, lead a corporate office, or manage an association, the Chamber of Commerce of the United States of America? provides you with a voice of experience and influence in Washington, D.C., and around the globe.

Our staff of experts—policy specialists, lobbyists, and lawyers—make up the world's largest not-for-profit business federation, representing:

3,000,000 businesses
2,800 state and local chambers
830 business associations
102 American Chambers of Commerce abroad
Our members include businesses of all sizes and sectors—from large Fortune 500 companies to home-based, one-person operations. In fact, 96% of our membership encompasses businesses with fewer than 100 employees.

The leadership is equally diverse, with more than 100 corporate and small business leaders from all sectors serving on the board of directors.

If your organization is not a member of the U.S. Chamber, there are plenty of reasons it should be. ...Reasons to Join
