Frequently asked questions
What is a NAICS code?
The North American Industry Classification System (NAICS) is the standard the U.S., Canadian and Mexican statistical agencies use to classify businesses by their primary activity. The 2022 edition has 1,012 six-digit industries in 20 sectors. Government buyers use NAICS codes to describe what a solicitation buys.
Why do NAICS codes matter for government bids?
Federal solicitations name one NAICS code, and its SBA size standard decides whether a business counts as small for that contract, including small business set-asides. Registering the right codes in SAM.gov also helps buyers and primes find you.
How do I find bids for my NAICS code?
Open your code's page to see matching open bids and save an email alert. Many state and local notices do not cite a NAICS code, so pair the alert with a keyword or category search.
Codes, titles and definitions: U.S. Census Bureau, North American Industry Classification System (NAICS), 2022. Size standards: U.S. Small Business Administration, Small Business Size Standards, 13 CFR 121.201 (eCFR text as of Oct 21, 2026). Open-bid counts cover bids that cite a NAICS code, refreshed every hour.
