SICCODE.com industry counts reflect verified business locations available for purchase. Headquarters and branches are counted separately, with each location classified by its primary NAICS and SIC industry. Duplicate locations are consolidated, and records that do not meet our verification standards are excluded. Counts represent available commercial business records, not all businesses operating in an industry.
Need businesses with an industry as a secondary activity? Additional targeting options are available by request.
