NAICS [North American Industry Classification System]
The North American Industry Classification System or NAICS (pronounced "nakes"[1]) is used by business and government to classify business establishments according to type of economic activity (process of production) in Canada, Mexico, and the United States of America. It has largely replaced the older Standard Industrial Classification (SIC) system; however, certain government departments and agencies, such as the U.S. Securities and Exchange Commission (SEC), still use the SIC codes.
