SIC
SIC Code: SIC or Standard Industrial Classification System was replaced by the North American Industry Classification System (NAICS) starting in 1997 but several data sets are still available with SIC based data. SIC and NAICS classify businesses by their primary type of activity. Users can choose the Primary SIC Only or the Secondary SIC Only or Both.
Search By Description: Users can search by description for the SIC codes by clicking on the "Search" button. The window will then show a list of business activities which users can use to target their list. Users can search through these options by clicking on the expand button to expand each section. To make a selection, users can click in a selection box to choose that description.
