Q. How do I identify the SIC or NAICS for an industry or company?

For more information, see NAICS and SIC on the Business Research guide, or watch this short video "How to find industry codes?"

One of the easiest ways to identify the NAICS or SIC for an industry is to look up a company in that industry using one of the business databases, e.g., Nexis Uni or Mergent Intellect. The descriptive information about the company almost always includes a listing of the industry or industries in which the company is engaged.

NOTE: NAICS replaced SIC in 1997, but some databases still include SIC codes in the listings.
