Industry Codes

To find industry codes, which are often used in business databases to find industry reports, use one of the following:

  • NAICS Directory: The North American Industry Classification System (NAICS) is the federal standard used to classify industries. It replaced the earlier SIC system, though SIC is still widely used (see below)
  • SIC Directory: Standard Industrial Classification (SIC) codes are four-digit numerical codes assigned by the U.S. government to business establishments to identify the primary business of the establishment
