Starting your business or industry research
To use many information sources, you must know the industry classification codes for the industry or company you want to research. Do you know your SIC and NAICS codes? If not, click here for NAICS codes. (HINT: It's pronounced "NAKES" codes)
Industry Codes
An industry code is a number that represents an industry or type of business. These codes were developed by the U.S. government to make it easier to group businesses into categories called "industries," and to collect information about those industries.
Until 1997, the government used the Standard Industrial Classification system (often called "SIC"). SIC codes are four-digit numbers. The government now uses a system called North American Industrial Classification System (NAICS). NAICS codes are five- or six-digit numbers.
For example, the SIC code for the ice cream manufacturing industry is "2024." The NAICS code for the same industry is "311520."
Many business information sources are arranged by SIC or NAICS codes, so it's helpful to know your code(s) to find the information you need.
