Section F, construction, holds 42,663 Ecuadorian company records as of 2026-10-01, 24,099 of them active. By province, Guayas leads with 11,764 (28% of the section), followed by Pichincha (10,371) and Azuay (2,339). The largest divisions are 41 (construction of buildings, 21,760) and 42 (civil engineering, 14,347); one further division completes it. That is 7.5% of the Ecuador 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 Ecuador, 100% of these rows carry an ISIC class; the registry publishes no size field; the registry publishes no website or e-mail; 3,271 were registered in the 12 months before the extraction. There is no street address at the source; location is province, canton and parish.
