The North American Industry Classification System (NAICS): Identification Tools

The North American Industry Classification System (NAICS) Identification Tools page provides users with drilldown tables to search for specific NAICS codes as well as codes from the previously used U.S. Standard Industrial Classification (SIC) system. Users may also search for NAICS codes by keyword or look up business listings in the provided company lookup tool. An additional feature on the site allows users to input old SIC codes to be converted into their current NAICS code.
