How NAICS codes work for federal contractors

What a NAICS code is. The North American Industry Classification System sorts businesses by what they do. Each code is six digits. The first two identify the sector (54 is professional, scientific, and technical services), and each further digit narrows the activity. The U.S. Census Bureau maintains the list and revises it every five years; the current edition is 2022.

How to find yours. There is no lookup by company name because codes are self-selected, not assigned. Three ways to land on the right one:

Describe what you do and search the classification (the finder above).
Look at how similar businesses classified themselves. SAM.gov's entity search shows the NAICS codes of any registered firm.
Read the Census definitions for the two or three closest codes and pick the one whose description matches most of your revenue.

Primary versus secondary. SAM.gov asks for one primary NAICS code and lets you add as many secondaries as apply. The primary should be the code that describes the largest share of what you sell. Secondaries cover the rest. Agencies search by NAICS when they post opportunities, so a code you leave off is an opportunity you will not see.

Why the code matters beyond registration. Each NAICS code carries a small-business size standard set by the SBA, expressed as either annual receipts or employee count. Whether you qualify as a small business on a given solicitation depends on the NAICS code the contracting officer assigned to it, not on your primary. Two firms with identical revenue can be "small" under one code and "other than small" under another.

When to revisit your codes. After a revision year, when you add a line of business, or when you notice opportunities you should be seeing are not appearing. Codes are easy to update in SAM.gov.

Always confirm codes against the Census Bureau's official listing before registering. This finder is a starting point, not a legal determination.

Results are based on the official 2022 NAICS classification. Always verify codes with the U.S. Census Bureau or a qualified consultant before registering in SAM.gov.

How do I get a NAICS code for my business?

You do not apply for one. You select it. Search the 2022 NAICS classification for the description that matches your main activity, then enter it as your primary code when you register in SAM.gov. You can change it later.

How do I find my NAICS code if I am already registered?

Search for your company in SAM.gov's entity search. Your primary and secondary NAICS codes appear on your registration record.

Can I look up a NAICS code by company name?

Only for businesses registered in SAM.gov, through the entity search there. There is no universal directory, because codes are self-assigned by each firm.

How many NAICS codes can I have?

One primary and any number of secondaries. Add every code that describes work you can actually perform; leave off codes you cannot deliver on, since they will surface opportunities you cannot pursue.

What is the difference between a NAICS code and a PSC code?

NAICS classifies your business. A Product Service Code (PSC) classifies what the government is buying on a specific contract. Both appear on federal solicitations. Use the PSC Code Lookup for the second one.

Do NAICS codes determine whether I am a small business?

Yes, in combination with SBA size standards. Each code has a size standard in dollars or employees. You are small for a solicitation if you are under the standard for the NAICS code assigned to that solicitation.

Is this NAICS finder free?

Yes. No account is needed to search, and there is nothing to sign up for.
