What is NAICS?

NAICS stands for North American Industry Classification System. It's the standard for classifying business establishments and it groups them according to similarity in the processes used to produce goods or services.

All industries will have at least one associated NAICS code.

What do the digits mean?

NAICS is a two- through six-digit system, offering five levels of detail. Each digit is part of a series of progressively narrower categories. Additional digits in the code signify greater classification detail.

The first two digits designate the economic sector.

The 3rd digit designates the subsector.

The 4th digit designates the industry group.

The 5th digit designates the NAICS industry.

The 6th digit designates the national industry.

The 5-digit NAICS code is the level at which there is comparability in code and definitions for most of the NAICS sectors across the three countries participating in NAICS (the United States, Canada, and Mexico).

The 6-digit level allows for the United States, Canada, and Mexico each to have country-specific detail.

A complete and valid NAICS code contains six digits.

What is an example?

Here's an example of different levels of NAICS codes and their meanings:

72: Accommodation and Food Services (sector)

722: Food Services & Drinking Places (subsector)

7225: Restaurants and Other Eating Places (industry group)

72251: Restaurants and Other Eating Places (NAICS industry)

722514: Cafeterias, Grill Buffets, and Buffets (national industry)

As you can see, the description becomes more specific with each digit.

Can you have more than one NAICS code?

Absolutely. Many companies have diverse business activities. For example, General Mills manufactures products from cereal to ice cream, so it'll have several 6-digit NAICS codes to represent these different types of business activities.

Likewise, your product or service may fit into more than one industry, so you may have more than one NAICS code that describes it.

What are SIC codes?

SIC is the Standard Industrial Classification system. NAICS replaced SIC in 1997. Other organizations and state/local agencies might continue to use the SIC for their own purposes. To find SIC codes and their descriptions, visit the Occupational Safety & Health Administration (OSHA) website, which maintains a SIC Manual.

To learn more about the differences between the original 1997 NAICS and SIC codes, visit the History tab on the NAICS website.
