NAICS (pronounced "nakes") 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. The North American Industry Classification System (NAICS) replaced the SIC system in 1997. NAICS uses six-digit codes to identify an industry. Many resources use these codes to identify a company’s activities, index companies by activity, and to define industry data and information.
