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.
