ABOUT SIC codes
What is a 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 public administration.
Reading a SIC Code
The first two digits of the code identify the major industry group,
the third digit identifies the industry group and the fourth digit
identifies the industry.
For example:
36 ELECTRONIC & OTHER ELECTRIC EQUIPTMENT
367 ELECTRONIC COMPONENTS & ACCESSORIES
3672 PRINTED CIRCUIT BOARDS
Note: The digit "9" is used in the third or fourth digit position of
the classification code to designate miscellaneous industries
not elsewhere classified (NEC). These miscellaneous
classifications are not comprised of homogeneous primary
activity groups. They are grouped together and treated as a
seperate industry in order to retain the homogeneity of the other
industries in the group.
In 1987 the Office of Management and Budget (OMB)
dramatically revised the SIC codes in accordance to the rapid
changing economy.
In 1992, as a direct result of the 1991 International Conference
on the Classification of Economic Activities, OMB established
the Economic Classification Policy Committee to develop a new
classification system. In 1997 it was announced that the new
system NAICS (North American Industrial Classification) would
strive for compatibility to include Canada and Mexico with a
thorough evaluation of incompatible areas in all three systems.
This will include all new and emerging industries, services, and
advanced technologies. It has been decided that the system will
go from a 4-digit (SIC) to a 6-digit (NAICS) system.。
