NAICS Code Finder
Describe what your business does in plain English and get ranked candidate NAICS codes, each with its official title, sector, and a short explanation of why it matched.
Results are AI-generated suggestions for you to consider and verify, not a determination of the code you must use. Every code shown is checked against the official 2022 Census NAICS list. Confirm your code with the official Census NAICS reference.
Got your code? Look up the SBA small business size standard for it with the SBA Size Standard Checker. Each result above links straight to its size standard.
Frequently asked questions
What is a NAICS code?
A NAICS (North American Industry Classification System) code is a 6-digit number that classifies a business by its primary activity. Federal agencies use NAICS codes to organize contracting opportunities and set small business size standards.
How does this NAICS finder work?
You describe your business in plain English. The tool uses AI to suggest the most likely 6-digit NAICS codes, then validates every suggestion against the official Census NAICS list and shows the official title and sector for each. It is pattern matching, not a determination of the code you must use.
Which NAICS code should I use?
This tool suggests candidates to consider; it does not decide for you. Your official code depends on your primary business activity. Confirm your selection against the official Census NAICS reference and your SAM.gov registration.
How accurate are the results?
Suggestions are AI-generated and may contain errors or omissions. Every code shown is a real 2022 NAICS code (codes the model returns that are not in the official list are dropped), but you are responsible for verifying the right code for your business.
