Professional services companies in Chile

There are 143,439 companies in ISIC section M (professional, scientific and technical activities) in Chile, 141,426 active. The section is 4.2% of the 3,392,321 Chilean records we hold from the RES (datos.gob.cl) + SII nómina, extracted 2026-08-03. The largest divisions are 70 (activities of head offices; management consultancy activities, 55,403) and 71 (architectural and engineering activities; technical testing and analysis, 28,652); 5 further divisions complete it. By region, Metropolitana de Santiago leads with 89,002 (62% of the section), followed by Valparaíso (12,280) and Biobío (8,316).

Consultancies, law and accounting firms, engineering offices, agencies and design studios. Division 70 also holds 'activities of head offices', where many group holding companies register, so it overstates consultancies. Division 69 is a channel in itself: accountants file for most small companies in Brazil and Colombia. Professional-services software, payroll, legal-tech and B2B marketing vendors buy this section. In Chile, 100% of these rows carry an ISIC class; size is known for 44%; the registry publishes no website or e-mail; 14,128 were registered in the 12 months before the extraction. An economic activity is registered for about half of Chilean RUTs, so this section undercounts companies that never registered one with the SII.
