About NAICS and SIC
The North American Industry Classification System (NAICS)
The North American Industry Classification System (NAICS) is replacing the
U.S. Standard Industrial Classification (SIC) system.
NAICS was developed jointly by the U.S., Canada, and Mexico to provide new
comparability in statistics about business activity across North America.
The North American Industry Classification System includes definitions for
each industry, tables showing correspondence between 1997 NAICS and 1987 SICs,
and a comprehensive index.
The Standard Industrial Classification (SIC) Code
Standard Industrial Classification (SIC) codes are four digit numerical
codes assigned by the U.S. government to business establishments to identify
the primary business of the establishment. The classification was developed
to facilitate the collection, presentation, and analysis of data; and to
promote uniformity and comparability in the presentation of statistical
data collected by various agencies of the federal government, state agencies,
and private organizations. The classification covers all economic activities:
agriculture, forestry, fishing, hunting, and trapping; mining; construction;
manufacturing; transportation; communications, electric, gas, and sanitary
services; wholesale trade; retail trade; finance, insurance, and real estate;
personal, business, professional, repair, recreation, and other services; and
The LogLink SIC/NAICS Codes Database Search
LogLink's searchable SIC/NAICS application uses the July 1998 U.S.
Census Bureau's NAICS and SIC Codes and Titles database. The application and
database provides browse and search features using the 1997 NAICS and 1987
SIC Correspondence Tables. For more information, visit the U.S. Census Bureau
