The North American Industry Classification System (NAICS) is a classification system to group businesses into similar industries for the primary purpose of tracking economic activity.  The code is used by government agencies in the United States, Canada, and Mexico.

The NAICS code is a number between 2-6 digits.  The shorter 2-digit codes are the broadly defined industry and become more specific as more numbers are added.

Within NAICS, there are 20 primary two-digit NAICS code classifications that are commonly referred to as sectors. For example, all Construction related businesses are under the NAICS two-digit code of 23.

After the sectors, there are 96 subcategories and 317 industry groups. You can identify subcategories by their three-digit codes, and industries by their four-digit codes. You may be wondering, “What is my NAICS code?” To properly determine your primary NAICS code(s), you must work down the classification scheme to identify the best fit for your business.

While it’s not uncommon for a business to have multiple codes, you will choose the primary NAICS that is closest to whatever the majority activity of the business is.

Besides tracking economic activity, some other uses of NAICS codes include:

  • Helping businesses find potential customers that operate in specific industries
  • Identifying whether a business can compete for government contracts
  • Filling out tax forms
  • Comparing financial performance against businesses in the same industry.

How to do a NAICS lookup

  1. Visit U.S. Census Bureau’s website
  2. Use the field for “2017 NAICS Search”

    Enter what your business does. For example “Restaurant” ,“Auto Repair”, “Grooming”, Etc., then click “Submit”. In this example, we searched for a restaurant.

  3. If you entered something too specific, no results will come in.  If that happens, try something more generic.  Instead of “Pizza Restaurant”, try “Restaurant”.   When you see a NAICS title that is closest to your business, click on the result.  If you aren’t sure, click on the listings to look at the overview to see which one is closest.  In this example, we looked at “Restaurants, full service”.

What is the difference between a NAICS code and SIC code?

The North American Industry Classification System (NAICS) code started in 1997 and replaced the Standard Industrial Classification (SIC) system.

SIC codes primarily focused on manufacturing and were kept up-to-date with service based and high-tech businesses.  Canada and Mexico along with the U.S. adopted the NAICS to better analyze and facilitate trade through the North American Free Trade Agreement (NAFTA).
