All industries will have at least one associated NAICS code.
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.
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.
Likewise, your product or service may fit into more than one industry, so you may have more than one NAICS code that describes it.
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.
