Federal contract opportunities by NAICS code
A NAICS code is how the government describes the industry a contract belongs to, and the code on each solicitation sets the size standard you must meet to count as a small business for it. Start with the code you are registered under.
278 listed, covering 6,380 open solicitations, counted November 5, 2026 at 11:41 PM EST from SAM.gov, which InstantSam reads every hour.
Each directory counts the open SAM.gov notices that carry its field: an agency, a six digit NAICS code, or a US state or territory as the place of performance. A listing needs at least three open notices to have a page. So the agency, NAICS and state totals differ, and all three are smaller than the count of every open notice on the home page.
