There are 70,252 companies in ISIC section F (construction) in Peru, 67,033 active. The section is 7.7% of the 916,523 Peruvian records we hold from the SUNAT Padrón RUC, extracted 2026-09-30. The largest divisions are 41 (construction of buildings, 39,309) and 43 (specialized construction activities, 15,935); one further division completes it. By department, Lima leads with 24,480 (35% of the section), followed by La Libertad (5,213) and Ancash (4,547).
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 Peru, 100% of these rows carry an ISIC class; size is known for 33%; the registry publishes no website or e-mail. EIRL names are masked (20,376 rows in this section); SUNAT publishes no registration date.
