What is a NAICS code?
The North American Industry Classification System (NAICS) gives every industry a code of 2 to 6 digits. Federal agencies tag every contract with one six-digit code, and it decides two things for you: which bids match your business, and whether you count as a small business, because SBA size standards are set per code.
How to choose yours
- Search for the work you do, and pick the most specific six-digit code.
- Add 3 to 6 codes that cover all your main work.
- Add them to your SAM.gov registration, and check your size against the SBA size standard for each.
- Watch open contracts under those codes: click any code above.
