The SII lookup needs the RUT; ChileAtiende documents it as a free, public service. Companies incorporated by public deed rather than through the RES are recorded in the Conservador de Bienes Raíces registers instead.
The RUT format
An 8-digit number and a check character (0-9 or K), written 76.123.456-7.
Every company at once
The lookups answer "does this company exist, and is it active?" one company at a time. For market sizing, territory planning or a prospect list you need the whole register, filtered by industry and region: Chile company data shows the counts by sector and region for free, with a 25-row sample, built from the RES (datos.gob.cl) + SII nómina.
