IEMS 403: Accounting for Engineers (Soffer): SIC/NAICS codes

SIC codes and NAIC codes

What are SIC and NAICS codes?

The Standard Industrial Classification (SIC) system is a US government system for classifying industries by four-digit code.  More recently, it is being supplanted by the North American Industry Classification (NAICS) system.  However, both systems are currently in use, depending on government agency or other information source.  In addition to industries, products, services and companies may be classified by SIC or NAICS.  Many of our business databases allow browsing and/or searching by these codes in order to identify companies, products, industries, etc.
