The North American Industry Classification System (NAICS) is the official standard used by the U.S. government to classify businesses for economic analysis, reporting, and regulatory purposes. Introduced in 1997 as the successor to the SIC system, NAICS has undergone multiple updates—most recently in 2022—to reflect the evolving structure of the economy.
