What is NAICS basically?

The NAICS Codes or the North American Industry Classification System (spoken as “nakes”) is a system based on the segmentation of established businesses on the grounds of economic activities. These NAICS Codes are generally used by the public sector and entrepreneurs based in Mexico, Canada, and the United States of America.

Well, as we may say, the NAICS Code is a much evolved and modernized form of the SIC Code system, i.e., Standard Industrial Classification System. However, in the public sector of the U.S., the SIC Codes are still existing. The numbering system of the NAICS Code consists of a five or six-digit code to specify and divide the industry levels. The initial five digits are the same (although not always) in all three countries. However, the first two digits represent the largest business sector. While the third digit represents the subsector, the fourth digit shows the type of industry group, and the fifth digit signals the NAICS industries. Lastly, the sixth digit represents the national industries.

How is NAICS structured?

The North American Industry Classification System Industries uses a hierarchical structure, which means every item is related to a specific category. These primary NAICS codes are signaled by a 6-digit code. Any code which is longer represents a larger number of sectors and contains more ease of designation subsectors. The international NAICS only allots the first five digits of the primary code. The last digit (sixth digit) shows the subdivision of NAICS industries that are allotted by individual countries. This means a 6-digit code in the U.S. will differ from the 6-digit code in Canada or Mexico.

The NAICS structure is as given below:

Sector 2-digit code
Subsector 3-digit code
Industry Group 4-digit code
NAICS Industry 5-digit code
National Industry 6-digit code

For example, NAICS Code 921130 is for Public Finance Activities. It is a 6-digit code where:

• Sector 92: denotes Public Administration
• Subsector 921: denotes sub categories (such as executive, legislative, and more general government support)
• Industry Group 9211: denotes executive, legislative, and more
• Industry 92113: denotes public finance activities
• 6 Digit Code NAICS 921130: Public Finance Activities
