Construction companies in Brazil

Section F, construction, holds 635,698 Brazilian company records as of 2026-10-10, all of them active. By state, São Paulo leads with 164,316 (26% of the section), followed by Minas Gerais (60,850) and Paraná (58,717). The largest divisions are 41 (construction of buildings, 359,712) and 43 (specialized construction activities, 230,559); one further division completes it. That is 5.8% of the Brazil registry in this build.

One of the largest sections in every registry and the noisiest: developers register a company per project (SPE/SPV), so division 41 overstates the number of operating builders. Division 43 (specialised trades) is where the actual contractors are. Construction-tech, building-materials distributors, equipment rental and fintech lenders use this section with a size or age filter. In Brazil, 100% of these rows carry an ISIC class; size is known for 69%; 15.5% have a corporate domain or HTTP-verified website; 68,155 were registered in the 12 months before the extraction. Brazilian rows are active establishments; 547,800 of them are head offices in the clean B2B universe (private, not sole-owner, name unmasked).
