NAICS (North American Industry Classification System) codes are 6-digit numbers that classify businesses by their primary type of economic activity. The federal government uses NAICS codes to categorize contract opportunities on SAM.gov and determine which businesses can bid on specific work.
When you register on SAM.gov, you select the NAICS codes that describe your business. These codes determine which contract opportunities you're eligible for and how the government finds you as a potential vendor. Choosing the right codes is critical — too few and you miss opportunities, too many and you dilute your profile.
