NAICS and SIC Codes

NAICS (pronounced nakes), or North American Industry Classification System:

  • numerical codes that identify industries or lines of business
  • can be 5 digits or more long.  More numbers, more specific the industry described.
  • can be used to search business databases

The NAICS system was meant to replace an older system called SIC (Standard Industrial Classification), but plenty of databases and reference books still use SIC codes.
