The U.S. Chamber defines small businesses as a company with $100 million or less in revenue.
There is no official certification process that determines a business as small. It is a self-certifying and paperless procedure. The U.S. Small Business Administration uses the North American Industrial Classification System (NAICS) in determining size standards; which as of October 1, 2000, replaced the Standard Industrial Classification (SIC) Codes.

To see if your business is considered small by the federal government, or to determine which NAICS Code is applicable to your business, visit Size Standard Topics at SBA.gov.

For businesses with over $100 million in revenue, the U.S. Chamber offers unique membership opportunities. If you qualify, fill out our National Accounts Signup form here to get started.
