North American Industry Classification System (NAICS) Codes Search List

The North American Industry Classification System or NAICS is a classification of business establishments by type of economic activity. It is used by government and business in Canada, Mexico, and the United States of America

The North American Industry Classification System (NAICS) is the standard used by Federal statistical agencies in classifying business establishments for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. business economy. It was developed to allow for a high level of comparability in business statistics among the three North American countries. NAICS is based on a production-oriented concept, meaning that it groups establishments into industries according to similarity in the processes used to produce goods or services.

Three sectors are represented by a range of 2-digit codes. These include Manufacturing (31-33), Retail Trade (44-45) and Transportation and Warehousing (48-49)

The organization of NAICS is as follows:
•   Sector: 2-digit code
•   Subsector: 3-digit code
•   Industry Group: 4-digit code
•   NAICS Industry: 5-digit code
•   National Industry: 6-digit code
