NAICS Code Lookup

A NAICS (North American Industry Classification System) code is a 2–6 digit number that classifies a business by its primary line of work. The federal government uses NAICS codes to organize procurement: every solicitation is tagged with the code(s) that describe the work, and contractors register the codes they serve so they can be matched to relevant opportunities.

Search this tool by keyword (for example, “software”, “landscaping”, or “engineering”) or type a code you already know to confirm its official title and see more specific codes beneath it. Pick the 6-digit code that most precisely matches your primary service — that is the level used in most government solicitations.

NAICS is a hierarchy: 2 digits is the broad sector, 3 the subsector, 4 the industry group, 5 the NAICS industry, and 6 the most specific national industry. Government solicitations almost always use the full 6-digit code, so that is the level most contractors register and bid under.

A NAICS code classifies the industry of the seller (what your company does); a PSC (Product and Service Code) classifies what is being bought in a specific contract. Federal award records usually carry both. Use NAICS to identify your industry and size standard; use PSC to filter for the exact products or services in a solicitation.

Yes. Most companies register several NAICS codes covering the different services they provide, with one designated as primary. Registering every code you can legitimately perform widens the set of opportunities you are matched to — which is exactly what BidSparq uses to score and surface the right contracts for you.

Yes. The SBA sets a small business size standard (a revenue or employee threshold) for each NAICS code, so your size status can differ from one code to another. This tool shows the official code and title; check the SBA’s table of size standards for the exact threshold that applies to your code.
