Online Matching Service for Home Owners and Contractors: NAICS/SIC Codes

NAICS and SIC Codes

  • NAICS codes (North American Industry Classification System) are keys to government data and company listings. Codes can be from two to six digits. 
  • Older US sources and some commercial databases still use SIC (Standard Industrial Classification) codes.
  • Why do you need a NAICS code?
    • Census databases organize industry data by NAICS codes.
