Q. How can I find SIC and NAICS industrial classification codes?

Using standardized codes can help you search for companies within an industry more effectively.  Many of our databases are searchable by NAICS or SIC codes.  Others will use their own proprietary industry classification system. Keep in mind that a company can be (and likely is, depending on the size) active in more than one industry so this may affect your searches.

The following sites can be used to learn more about the NAICS and SIC classification systems and their codes.
