NAICS

The North American Industry Classification System is the standard used by federal agencies to classify business establishments according to their primary economic activity. Each NAICS code is a six-digit number identifying the industry sector, subsector, industry group, and specific industry.

In government contracting, NAICS codes determine small business size standards and are used to categorize contract opportunities. Agencies assign NAICS codes to solicitations, and contractors must meet the associated size standard to qualify as a small business for that procurement. Selecting appropriate NAICS codes for your SAM.gov profile affects which set-aside opportunities you can pursue and how you appear in market research searches.
