Searching with Industry Codes

The North American Industry Classification System (NAICS) is the standard used by Federal statistical agencies in classifying business establishments for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. business economy. It is important to know the NAICS codes associated with your business because you will use them while searching for resources. 

Major Classification Systems
