The North American Industry Classification System (NAICS) is used by the United States, Mexico and Canada to help identify industry performance and forecast economic conditions.

This article will provide a clearer understanding of how NAICS codes are assigned and how they are used:


The NAICS is an abbreviation from the North American Industry Classification System. The NAICS are standard codes assigned to business sectors and industries that can be used for statistical purposes in classifying businesses for collecting, analyzing, and publishing data related to the United States economy.

NAICS history

NAICS was adopted in 1997 to replace the Standard Industrial Classification (SIC) system. This was a joint effort between the United States, Mexico, and Canada to allow for a better comparability in business statistics among the North American countries.

Your NAICS code is self-assigned by you. To determine your company’s NAICS code, go to NAICS at the U.S. Census Bureau's website.

You can search for your business NAICS code by entering keywords or the 2-6 digit code.

How is the NAICS code used?

Federal and state agencies use the NAICS to classify businesses when collecting, analyzing, and publishing statistical data about the United States economy.

This numeric coding system is also used for regulatory, contracting, and taxation purposes. Some states may use your NAICS code to determine your new employer rate when registering for a payroll tax account.

Why do I need a NAICS code?

There are many reasons why you should be aware of your NAICS code, or at the very least the industry your company would be used for statistical reporting.

  1. Industry trends - Knowing how your industry is adapting to current political and economic conditions allows you to properly forecast your business needs. This also allows you to stay informed of regulatory and policy changes that may impact your business operations.

  2. Taxes - NAICS codes are used to determine tax incentives, and business expenses when reporting taxes. Using an incorrect NAICS code can result in a greater chance of being audited.

  3. Financing - NAICS codes are used by banks to determine a company's risk when lending funds. When banks lend money, they will use your industry’s NAICS code to determine if your company aligns with their portfolio with expected risk and return.

  4. Government programs - The government uses NAICS codes to identify when granting businesses contracts and tax incentives. Knowing your NAICS code will make it easier in finding government programs and contracts.

  5. Marketing - NAICS codes can be helpful with identifying your customers and competitors. Using your customers’ NAICS codes allows you to better differentiate yourself from your competitors, and effectively market your product and services.

Do NAICS codes change?

Yes, NAICS codes change every five years. 2022 was the last year the NAICS codes were reviewed and changed. During this time codes existing codes may be amended, and new codes will be added.

You can still review previous NAICS codes at the US Census website.

NAICS classification

The NAICS code can be 5 or 6 digits. The first 5-digits of the NAICS code are standard reporting in the United States, Mexico, and Canada. NAICS codes having 6-digits means one of the three countries will use the last digit for their own use when compiling and reporting data.

The NAICS classification:

  • Sector: 2-digit code

    • Subsector: 3-digit code

      • Industry Group: 4-digit code

        • NAICS Industry: 5-digit code

          • National Industry: 6-digit code
