What is a NAICS code?

NAICS is the North American Industry Classification System — a six-digit numeric code jointly maintained by the United States, Canada, and Mexico. Each code identifies a specific industry, narrowing from a broad two-digit sector (for example, 54 covers all of "Professional, Scientific, and Technical Services") down to a precise six-digit national industry such as 541511, "Custom Computer Programming Services." The system is updated roughly every five years; the current revision is NAICS 2022, and most procurement portals — SAM.gov, CanadaBuys, the Quebec SEAO, state and provincial systems — have adopted it. When a buying agency posts a contract opportunity, they tag it with one or more NAICS codes so vendors can filter for work that fits their business. When you register as a vendor (in SAM.gov, on CanadaBuys, or with a province), you list the NAICS codes you serve. The match between those two sides is how most government tender notifications get routed.

For contractors, NAICS matters in three concrete ways. First, eligibility: many federal set-asides — small business, woman-owned, service-disabled veteran-owned, HUBZone in the US; Indigenous Procurement and CCAB-certified set-asides in Canada — are scoped against a specific NAICS code, and the size standard (revenue cap or employee cap) that determines whether you qualify as "small" for that opportunity is set per code. Second, routing: tender alert systems (including GovBid) use NAICS codes to decide which opportunities to surface to which vendors, so a wrong primary code means a stream of irrelevant alerts and missed real ones. Third, market research: the US Census Bureau and Statistics Canada publish revenue, payroll, and establishment counts at the 6-digit NAICS level, which lets you size a market, benchmark competition, or build a B2G business case before you spend a dollar on bid prep.

Picking the right code is less mysterious than it looks. Your primary NAICS code should be the one that describes the activity generating the majority of your revenue today — not your aspiration, not your most prestigious project, but the work that actually pays the bills. If you do custom software for government clients, that's 541511. If you build commercial buildings, that's 236220. From there, list secondary codes for adjacent work you genuinely perform — a software firm that also runs managed-services contracts might add 541513 (Computer Facilities Management) and 541519 (Other Computer Related Services), for example. Adding wildly off-topic secondary codes hoping to catch more alerts is a common rookie mistake: it dilutes your relevance score on most matching engines and creates audit risk on set-aside bids. When in doubt, look at how your three biggest past contracts were classified by the buyer — that's usually the cleanest signal. Use the search above to confirm the title and definition match what you actually do.

Ready to see live tenders?

Once you know your NAICS code, the next step is finding open contract opportunities that match it. GovBid tracks open tenders from CanadaBuys, the Quebec SEAO, CivicInfo BC, SaskTenders, BidsAndTenders, the City of Toronto, and more — all searchable for free.

Data: NAICS 2022 v1 (curated 173). NAICS is jointly maintained by the US Census Bureau, Statistics Canada, and INEGI (Mexico) and is in the public domain. The full NAICS 2022 list contains 1,057 six-digit codes; this tool ships with the 173 codes most frequently cited in Canadian and US government tender notices and will be expanded over time.
