NAICS or The North American Industry Classification System is used for the classification of organizations by the type of their economic activity. It is used by governments and organizations in the United States, Canada, and Mexico, but is also common in many other countries.
NAICS codes include five or six digits at the most detailed industry level. The first two digits indicate the broad business sector, the third digit indicates a subsector, the fourth digit indicates the industry group, the fifth digit indicates the NAICS industries, and the sixth digit shows the country-specific industries.
- Sector: 2-digit code
- Subsector: 3-digit code
- Industry Group: 4-digit code
- NAICS Industry: 5-digit code
- National Industry: 6-digit code
- NAICS Industry: 5-digit code
- Industry Group: 4-digit code
- Subsector: 3-digit code
Three sectors are represented by a range of 2-digit codes instead of 1-digit code. These sectors are Manufacturing (31-33), Retail Trade (44-45), and Transportation and Warehousing (48-49).
