What is a NAICS Code?

The NAICS coding system is used to classify businesses by industry. NAICS (pronounced as “nakes”) code was created by the federal and statistical governments of the US, Canada, and Mexico.

Through the NAICS coding system, these government agencies are able to categorize businesses so they can analyze and publish economic data.

The NAICS code system was introduced in 1997 to replace the Standard Industrial Classification (SIC) system. You can renew or make changes to your NAICS code every five years. The last update was made in 2017 and will affect new changes in 2022. The next scheduled review of NAICS will be for a 2027 revision.

NAICS codes provide businesses with tools to quickly and accurately conduct research on specific industries. Locate and choose the proper NAICS code by using our NAICS Code Lookup tool that best represents your company:

What are the Common NAICS Codes?

Step 2: Select Your Industry

In the NAICS code lookup search bar, enter a keyword that best fits your primary type of business activity. There will appear a list of industry titles containing that keyword with the corresponding NAICS codes.

For example, once you enter a key search phrase such as “real estate” or “insurance”, you’ll find a list of NAICS codes that will match your query.
