Some market research databases and websites organize business information using industry codes.
The two industry classification systems you will come across most often are NAICS and SIC. Both are hierarchical, organized by broad industry categories, each divided into more specific industries.
Note: If you are researching a very specific or very new industry, it may not be included in these industry classification systems.
To identify companies operating within an industry, search company directories available online or in print through the library or free on the Internet.Directories typically contain contact information, such as the address, telephone number, and key executives or personnel. Some directories may offer minimal financial and profile information, as well. Most can be searched by industry and some are organized by industry codes.
