Standard for classifying business establishments
The
North American Industry Classification System
or
NAICS
(
)
[1]
is a
classification of business establishments
by type of economic activity (the process of production). It is used by governments and business in
Canada
,
Mexico
, and the
United States of America
. It has largely replaced the older
Standard Industrial Classification
(SIC) system, except in some government agencies, such as the
U.S. Securities and Exchange Commission
(SEC).
An establishment is typically a single physical location, though administratively distinct operations at a single location may be treated as separate establishments. Each establishment is classified as an industry according to the primary business activity taking place there. NAICS does not offer guidance on organizing enterprises (companies) composed of multiple establishments.
Codes
[
edit
]
The NAICS numbering system employs a five or six-digit code at the most detailed industry level. The first five digits are generally (although not always strictly) the same in all three countries. The first two digits designate the largest business sector; the third digit represents the subsector; the fourth digit represents the industry group; the fifth digit designates the NAICS
industries
, and the sixth digit represents the national
industries
.

History
[
edit
]
NAICS is a collaborative effort by Mexico's
Instituto Nacional de Estadistica y Geografia
(INEGI),
Statistics Canada
, and the
United States Office of Management and Budget
(OMB), through its Economic Classification Policy Committee (ECPC), staffed by the
Bureau of Economic Analysis
(BEA), the
Bureau of Labor Statistics
(BLS), and the
Census Bureau
. The system is designed to be largely compatible with the
United Nations
Statistical Office's
International Standard Industrial Classification
system (ISIC). NAICS versions are released every five years.
With the first version, released in 1997, NAICS offered enhanced service sector coverage relative to the SIC. The 2002 revision accommodated significant changes in the Information Sector. The 2012 revision slightly reduced the number of industries and modified six sectors.
[5]
NAICS changes are done at intervals of five years; the latest NAICS updated in 2022.
