Industry Codes & Classification

NAICS: North American Industry Classification System
Replaced the U.S. Standard Industrial Classification (SIC) system in 1997; it's a 5- or 6-digit number. You can search by keyword, and there are tables to convert from NAICS to SIC, and SIC to NAICS. The NAICS was developed jointly by the U.S., Canada, and Mexico to compare statistics about business activity across North America.
SIC: Standard Industrial Classification
The U.S. government classified business activity according to the SIC system until the adoption of NAICS in 1997. It's searchable by code or by keyword. Some business sources still feature SIC code search options.
North American Product Classification System (NAPCS)
3-5 digit classification system for products produced by service industries in 12 NAICS sectors in the 48-49 through 81 divisions. Is a complement to NAICS and organizes products primarily by their use. Implementation started in 2007.

What is a NAICS Code?

The North American Industry Classification System (NAICS) is used to organize industry information. It's designed to produce common industry definitions for Canada, Mexico, and the United States. It is a hierarchical classification system, offering five levels of detail. Codes are assigned to an industry based on products and services provided by the industry.

Industries are represented by a six-digit number. The first two digits designate the economic sector: manufacturing, agriculture, wholesale, retail, professional services, etc. The subsequent digits designate subsectors and industry groups.

Each digit in the code is part of a series of progressively narrower categories.

Example:

72 - Accommodation and Food Services

722 - Food Services and Drinking Places

7225 - Restaurants and Other Eating Places

722511 - Full Service Restaurants

The Standard Industrial Classification (SIC), an earlier U.S. system, is still used by some sources.
