The North American Industry Classification System (NAICS) is an economic classification system introduced in 1997 to replace the 1987 SIC system. NAICS codes are 6 digit numerical codes used to identify the primary line of business of North American establishments. Many large enterprises have multiple lines of business, and therefore they express multiple codes.
The classification was developed to facilitate the collection, presentation, and analysis of data; and to promote uniformity and comparability in the presentation of statistical data collected by various agencies of the federal government, state agencies, and private organizations. This new system was developed jointly by the U.S., Canada, and Mexico, to make international comparisons easier.
