Construction companies in Argentina

Argentina's Registro Nacional de Sociedades lists 78,441 companies in construction (ISIC section F), all of them active, which is 6.2% of all Argentine records in the LatSouth build (data as of 2026-09-18). By province, Ciudad Autonoma Buenos Aires leads with 23,819 (30% of the section), followed by Buenos Aires (21,967) and Cordoba (6,099). The largest divisions are 41 (construction of buildings, 54,427) and 43 (specialized construction activities, 13,764); one further division completes it.

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 Argentina, 100% of these rows carry an ISIC class; the registry publishes no size field; the registry publishes no website or e-mail; 2,172 were registered in the 12 months before the extraction. Argentina publishes no company status, so 'active' means at least one active activity row; the 28% of Argentine companies with an unmapped legacy code fall outside every ISIC section.
