Questions

What is a NAICS code?
NAICS (the North American Industry Classification System) is the standard the US, Canada and Mexico use to classify business establishments by their main activity. Each code has two to six digits, and every digit narrows it down: 72 is Accommodation and Food Services, 722 Food Services and Drinking Places, and 722513 Limited-Service Restaurants.
What is my NAICS code?
If your business has a website, type it in the box above. If it is new or small and not found, type what it does in Find a code (for example "lawn care" or "bakery") and pick the six-digit code that describes your main activity, then read its definition to confirm. That six-digit code is the one forms ask for.
Which NAICS code do I put on SAM.gov or an SBA form?
The six-digit code that best describes your main activity. No agency assigns it to you: you choose it. SAM.gov lets you list several codes and mark one as primary. SBA size standards are set per NAICS code: for a federal contract the code on the solicitation applies, and for an SBA loan your primary activity does.
Who assigns NAICS codes?
No government agency assigns one official NAICS code to a company. Businesses choose their own codes on forms such as SAM.gov registrations and tax returns, statistical agencies classify establishments for their surveys, and data providers like Crustdata classify companies by their main activity. The SEC assigns its own SIC code to every public filer.
How do I find a company's NAICS code?
Type the company's name or website in the box above. The lookup matches the company and shows the primary NAICS code in Crustdata's data, with every level of the hierarchy and its official title. A website gives the most exact match. For an official record, check the company's SEC filings (SIC code) or its SAM.gov registration (NAICS codes).
What is the difference between NAICS and SIC codes?
SIC (Standard Industrial Classification) is the older system, last revised in 1987, with four-digit codes. NAICS replaced it in 1997 and is revised every five years; these are the 2022 codes. Many lenders, insurers and data providers still ask for SIC, and the SEC still assigns a SIC code to every public company, so the lookup shows both.
How do I look up a company's SIC code?
Type its name or website in the box above. The lookup shows every SIC code on file with its 1987 title, major group and division, and the ones that match the NAICS code come first. Find a code also takes a four-digit SIC number and shows the matching NAICS codes.
How many digits is a NAICS code?
Six at the most detailed level. The first two digits are the sector, the third the subsector, the fourth the industry group, the fifth the NAICS industry and the sixth the national industry. Shorter codes are the broader levels.
Can a company have more than one code?
Yes. NAICS classifies each business location by its main activity, so a company with several lines of business can have locations under different codes, and forms often let you list more than one. The code shown here is the primary NAICS code in Crustdata's data. A company can also carry several SIC codes; the ones that match the NAICS code are listed first.
Is this NAICS code lookup free?
Yes. You get 10 lookups with no sign-up, and 20 more when you enter your email. After that, a free Crustdata account lets you keep going in the app or through the API.
What if a company has no code?
Crustdata holds NAICS codes for millions of companies, but not every one. When a company has no code on file, the lookup shows how it is otherwise tagged and does not count against your free lookups. You can then find the code by what the company does.
What year are these codes?
NAICS codes are the 2022 edition, the one in use in 2026. SIC codes are the 1987 edition, the last one published. Titles and definitions come from the US Census Bureau (NAICS) and the SIC manual.
How do I find all companies with a NAICS code?
Popular codes have their own page listing the largest companies that carry them; browse the sectors to find one. To get every company with a code, with filters and export, use a free Crustdata account.
Where does the data come from?
The codes for each company come from Crustdata's company dataset, which covers 60M+ companies. The official titles and definitions come from the public NAICS and SIC manuals.
