NAICS Code Guide
What is a NAICS code?
NAICS stands for the North American Industry Classification System. U.S. government agencies use it to classify businesses by their primary economic activity. Businesses may encounter NAICS codes in registrations, surveys, lending, procurement, insurance, tax forms, and compliance workflows.
How do I choose a NAICS code for my business?
Start with the activity that produces the largest share of your business revenue or is your primary activity. Search for that activity, then compare nearby detailed descriptions before choosing a code.
Is a NAICS code the same as an EIN?
No. An EIN is a federal tax identification number issued by the IRS. A NAICS code classifies the type of business activity. A business may need both in different contexts.
How many digits are in a NAICS code?
NAICS codes in this finder range from 2 to 6 digits. More digits generally mean a more specific industry classification.
Where can I confirm a NAICS code?
Use the U.S. Census Bureau's official NAICS site and follow the guidance of the federal, state, or private organization requesting the code.
