NAICS or SIC Codes

NAICS is the North American Industry Classification System, a standard implemented in 1997 for classifying industry, product, and establishment. Use this site to find your industry NAICS code. Click on the relevant code to read its description and to ensure that you have the right code.

Different sectors of industry are classified according to NAICS (North American Industry Classification System) codes.

NAICS codes are hierarchical

The codes are 6 digits long, but you can use just part of the code in order to search a broader group of industries. For instance, "Confectionery Manufacturing from Purchased Chocolate" has the code 311330, but the shorter 3113 works for all of the different industries that fall under "Sugar and Confectionery Product Manufacturing". If you're searching using an NAICS code and you're not finding much, try lopping a digit or two off of the end of the full 6-digit code and you may have better luck.
