NAICS Code - The North American Industry Classification System (NAICS) uses six-digit codes to identify an industry. The NAICS system is gradually replacing the SIC system. Many resources use these codes to identify a company’s activities, index companies by activity, and to define industry data and information. For more information on the history and structure of the NAICS, as well as to search for codes, visit the NAICS Association website at http://www.naics.com/ and the U.S. Census Bureau at http://www.census.gov/eos/www/naics/.
SIC Code - Standard Industrial Classification (SIC) codes are four-digit codes used 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. For information on the history of the SIC codes and information about its replacement, the NAICS, visit the NAICS Association website at http://www.naics.com/info.htm. An excellent website for a list of SIC codes and to search for a code is the OSHA site from the U.S. Department of Labor at http://www.osha.gov/cgi-bin/sic/sicser5.
