Every company or business is part of an industry. Likewise, every product fits into an industry. Industries have been defined and codified by the U.S. federal government. Some industry information is organized by the industry code (a number) rather than the industry name. There are several ways to identify the industry and obtain the industry code.
Industry codes are used to classify and categorize individual industries. There are several major industry code systems: Standard Industrial Classification (SIC) and North American Industry Classification System (NAICS) were created and are maintained by the U.S. government. When searching some business databases, you can use SIC or NAICS codes as a keyword. To find the appropriate industry code, please use the SIC and NAICS sources below.
