Industry codes

Industrial classification codes (SIC and NAICS) are used to organize industry data and documents into broad topical areas. IBISWorld, Mergent Online, Mergent First Research, Mergent Intellect, ABI/INFORM and Business Source Premier databases have industry code look-up functions. The look-up functions allow you to search code descriptions by keyword, then select classification codes from a list. 

Several library databases provide industry code look-up functions which allow you to search the NAICS or SIC code descriptions by keyword and select codes from drop-down lists. 

Industry code searches enable you to:

  • limit search results to a specific industry
  • locate companies within an industry
  • find industry overviews, analysis reports, statistics, forecasts and market trends

Industry codes serve to define broad topical areas such as a management function, an industry, a market, or an organization type. For example, NAICS Code 5418 covers Advertising, Public Relations, and Related Services. In the ABI/INFORM business database, clicking on “Look up classification codes” will open a list of broad categories and nested sub-categories. Check boxes are provided to limit your search results to specific industries, markets or management functions.

Detailed descriptions and historical information about the SIC and NAICS industrial classification systems can be found on the website at
