The North American Industry Classification System (NAICS) is the standard used by Federal statistical agencies in classifying business establishments for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. business economy.
NAICS was developed by the Office of Management and Budget (OMB), and adopted in 1997 to replace the Standard Industrial Classification System (SICS). These codes are good to know because providers of Industry information often use them classify to industries.
