What is an NAICS code?
The North American Industry Classification System, also known as NAICS, replaced the U.S. Standard Industrial Classification (SIC) system in 1997. NAICS was developed jointly by the U.S., Canada, and Mexico to provide new comparability in statistics about business activity across North America.
