About Industry Codes

According to the United States Census Bureau, both the Standard Industrial Classification (SIC) and North American Industrial Classification System (NAICS) classify establishments by their primary type of activity. Companies generally determine their own codes based on descriptions provided in each system, and can thus be compared to other like companies. This structured information enables economic analysis on a local, national, and to some extent, international basis.

To find an NAICS code, visit the NAICS site of the United States Census Bureau.
