SIC and NAICS Codes

When searching industry information, it is often helpful to have the SIC or NAICS codes for your industry. SIC (Standard Industrial Classification) and NAICS (North American Industry Classification System) are standard numbering systems for identifying the industry affiliation of individual companies.  The heirarchical structure of both numbering systems allows for searching broad industry groups as well as specific industry segments.

Public vs. Private

When searching for company information, one of the first things you should do is determine if the company is Public or Private. 

Public companies (i.e. companies that issue stock that is publicly traded in the various stock exchanges) are required to make certain information available to potential investors.   As a result, it is usually easier to locate information (particularly financial information) about public companies. 

Private companies (wholly-owned by individuals or families or have stock that is closely-held by a small number of investors) do not have the reporting requirements of public companies.  Consequently, finding or verifying information (particularly financial information) is much more difficult for these types of companies.
