Frequently asked questions
What is a NAICS code?
The North American Industry Classification System (NAICS) is the standard the U.S., Canada and Mexico use to classify businesses by their primary activity. Codes run from 2 digits (the sector, e.g. 31-33 Manufacturing) to 6 digits (the national industry, e.g. 332710 Machine Shops); each extra digit is a more specific industry.
How are companies counted under a NAICS code?
A company is counted under every code it is classified with and under each of their parent codes, once per code. The count for a sector therefore includes every company under its subsectors, industry groups and industries.
