North American Industry Classification System - NAICS

For more information goto:

NAICS, which has replaced the SIC (Standard Industry Classification), is an industry classification system that groups establishments into industries based on the activities in which they are primarily engaged. It is a comprehensive system covering the entire field of economic activities, producing and nonproducing. There are 20 sectors in NAICS and 1,170 industries in NAICS United States.

In July 1992, the Office of Management and Budget (OMB) established the Economic Classification Policy Committee (ECPC) and charged it with a ‘‘fresh slate’’ examination of economic classifications for statistical purposes. The ECPC prepared a number of issue papers regarding classification, consulted with outside users, and ultimately joined with Mexico’s Instituto Nacional de Estadística, Geografía eInformática (INEGI) and Statistics Canada to develop the North American Industry Classification System (NAICS), which replaces the 1987 U.S. SIC and the classification systems of Canada (1980 SIC) and Mexico (1994 Mexican Classification of Activities and Products (CMAP)).

NAICS in the United States was designed for statistical purposes. However, NAICS is frequently used for various administrative, regulatory, contracting, taxation, and other non-statistical purposes. For example, some state governments offer tax incentives to businesses classified in specified NAICS industries. Some contracting authorities require businesses to register their NAICS codes, which are used to determine eligibility to bid on certain contracts. The requirements for these non-statistical purposes played no role in the initial development of NAICS or its later revisions.
