NAICS code search for federal contractors
Search the current 2022 NAICS codes by keyword or number to find the classification that matches what your business sells. Every federal contract is tagged with a NAICS code, and the code you enter in SAM.gov determines which set-asides and size standards apply to you — so picking the right one matters more in federal contracting than anywhere else. Free, no signup.
What NAICS code is my business?
Your NAICS code is the 6-digit classification matching your primary business activity — the one generating the most revenue. Search by keyword describing what you actually sell, not your job title or industry buzzword. The Census Bureau maintains the official definitions in the 2022 NAICS revision.
How many NAICS codes can I list in SAM.gov?
You can list multiple NAICS codes in your SAM.gov registration and should list every code you can genuinely perform under, but one is designated primary. Listing codes you cannot perform hurts you — contracting officers check.
What is a NAICS size standard?
Each NAICS code carries an SBA size standard — a maximum annual receipts figure or employee count below which you count as a small business for that code. The same company can be small under one code and large under another, which is why code selection affects set-aside eligibility. Standards are published in 13 CFR 121.201.
Does my NAICS code have to match the solicitation's?
The contracting officer assigns the NAICS code to the solicitation, and your size status is measured against that code's size standard. You do not have to have listed it beforehand to bid, but having it in SAM.gov supports your credibility and helps agencies find you in market research.
Which NAICS revision is current?
The 2022 NAICS revision. NAICS is revised on a five-year cycle, so confirm against census.gov/naics before relying on a code in a filing.
