Business: SIC & NAICS Codes

Find NAICS or SIC Codes

The Standard Industrial Classification (SIC) and North American Industry Classification System (NAICS) are classification systems that the United States government created in order to group similar companies together for the purpose of analyzing data. SIC uses a four-digit system, and NAICS uses a six-digit system. Use these government websites to find SIC or NAICS codes, or to compare the two systems.
