Use NAICS Codes

What are SIC and NAICS codes?

Many business databases and other research tools use industry codes to classify and organize industries. SIC/NAICS codes can help you find and compare companies in specific industries.

The SIC Code:
(Standard Industrial Classification System) is a four-digit numerical scheme used to classify businesses according to industry type. Companies in the same industry are assigned the same number or SIC code. For example, General Motors, Ford Motor Corporation, Honda, and Toyota were all assigned the SIC code of 3711.

NAICS code:
The SIC code has been updated by the six-digit North American Industry Classification System (NAICS code). While the NAICS system is more up-to-date than the SIC system, many databases and agencies still use SIC codes exclusively (including the U.S. Securities and Exchange Commission (SEC). Look for both NAICS and SIC codes when doing business research. To convert SIC codes to NAICS codes (or vice versa), use the SIC and NAICS Correspondence Tables.

International Industry Codes:
European uses the NACE (Nomenclature of Economic Activities) Code, and the United Nations developed the International Standard Industrial Classification (ISIC). ISIC and NACE have exactly the same items at the highest levels, where NACE is more detailed at lower levels.
