Sources, licence and attribution

• Primary: Registro de Empresas y Sociedades (RES), Ministerio de Economía, Fomento y Turismo, datos.gob.cl, CC BY — RUT, legal name, legal form, incorporation date.
• Enrichment: Servicio de Impuestos Internos (SII), Nómina de Personas Jurídicas y Empresas (Aug 2026; Empresas AC2024), www.sii.cl — status, activity, address, sales band, workers. Published as active transparency with no declared licence; used as enrichment and flagged per row (source_license = SII-undeclared). If you need a CC BY-only file, set only_res_registered and rely on the RES fields.

ENRICHMENT: SII, Nomina de Personas Juridicas y Empresas (ago/2026; Empresas AC2024), www.sii.cl; sin licencia declarada (transparencia activa), uso como enriquecimiento [vigencia, actividad, domicilio, tramo de ventas, trabajadores].

Limitations

• ISIC coverage is ~70% of active companies: 1.65M RUTs have no activity in the SII files (58% of those are terminated). Industry filters only see companies with an activity.
• Size is known for 31% and workers for 40% of active companies (SII publishes them only for companies in its AC2024 statistics); size_class = unknown otherwise.
• Sole-owner companies (EIRL, empresas individuales) and sociedades de hecho have their name masked (***) and are excluded by default. SpA with a single shareholder are not identifiable and are kept.
• No e-mail, phone or website is published by Chilean registries.

Pricing

Pay per event: company-result, US$0.003 per company row returned (1,000 = US$3). Set a maximum cost per run and the actor stops when it is reached (OUTPUT.stopped_by_budget). Full files and custom segments: https://latsouth.com/data/chile/.
