What is my NAICS code?
Your NAICS codeis how the government classifies your line of work — and it's the first thing you need before you can bid. Search below by what you do, not by the official jargon: type “roofing” and we'll show you 238160, type “561720” and we'll confirm it's Janitorial Services.
- What is a NAICS code?
- NAICS — the North American Industry Classification System — is the 6-digit code the federal government uses to describe what your business does. It's how agencies categorize the work they're buying, and how they decide which size standard applies to a contract.
- Why does it matter for government contracts?
- Every solicitation lists the NAICS code the buyer assigned to it. Your code determines which opportunities show up for you and which SBA small-business size standard you're measured against. Picking the right primary code is part of setting up your SAM.gov registration.
- Can I have more than one?
- Yes. Most contractors qualify under several NAICS codes — you'll choose a primary code and can list additional ones in SAM.gov. Use this finder to identify every code your trade touches.

Try a plain-English term like “plumber”, “commercial cleaning”, or “IT services” — or type a partial code like “2382”.
