Identify your Industry Code

NAICS (North American Industry Classification System) code is used to classify businesses according to type of industry in Canada, Mexico and the United States. It was meant to replace the older SIC (Standard Industrial Classification) codes; however, certain government departments and agencies, such as the U.S. Securities and Exchange Commission (SEC), still use the SIC codes.
