Businesses often use SIC codes to identify companies within specific industries for marketing purposes. By determining the SIC code of their best clients, they can use this information to successfully acquire more customers within that industry.

  • Why were Extended SIC Codes created?

    The U.S. Government was aware of certain limitations of the official 4-digit SIC Code system and allowed for the creation and usage of Extended SIC Codes by private companies and agencies. The business world seized on the opportunity to extend the SIC Code system and there are currently three separate but relatable Extended SIC Code systems in place - 6-digit, 7-digit, and 8-digit systems. The creation of these systems allowed marketers to focus their campaigns on a more precise level and avoid unnecessary costs; while devoting resources to the specific industries that matter. Another benefit of the Extended SIC Code system is the continuous updating of evolving and emerging industries by the Private industry, which occurs at a much quicker pace than the 5-year update of NAICS.
