Overview

The North American Industry Classification System (NAICS) is the federal standard for classifying business establishments to support the collection, analysis, and publication of statistics on the U.S. economy. Developed under the auspices of the Office of Management and Budget and first issued in 1997, NAICS is a trinational framework with Canada and Mexico designed for cross-country comparability; the current NAICS vintage is 2022. ¹
