Chile Company RUT Lookup — SII Company Data

Look up Chilean companies by RUT or search them by name, economic activity, comuna, region, size and start date. Every record comes from Chile's official open data: the public legal-entity lists of the Servicio de Impuestos Internos (SII) and the Registro de Empresas y Sociedades published on datos.gob.cl.

For each company you get:

• Normalized RUT (90749000-9 and 90.749.000-9) and check-digit (DV) validation
• Legal name (razón social), entity type and legal form (SpA, Ltda., EIRL, S.A., foundation, public body...)
• Start of activities (inicio de actividades) and termination date (término de giro), plus an isActive flag
• All registered economic activities: SII code (CIIU4.CL), description, since-date, VAT applicability, tax category
• Head-office address with comuna and region, and the list of current branches (sucursales)
• Company size from the SII: sales bracket (micro / small / medium / large), number of employees, economic sector and tax regime
• For companies created since 2013 under the "empresa en un día" registry: constitution date and initial capital (CLP)

Legal entities only. RUTs in the natural-person range are rejected without lookup, and SII taxpayers without legal personality (estates, de-facto partnerships named after people, marital communities) are not in the data at all. No representative, partner or owner fields exist in the output.

Why this actor

• Fast and cheap: the whole SII company list (≈3.2 million legal entities) is pre-indexed inside the actor. A 2,000-RUT lookup finishes in about 5 seconds; a filtered search for 5,000 companies in about 7 seconds.
• Official, not scraped from a third-party site: data comes straight from sii.cl and datos.gob.cl open-data files.
• Always correct for lookups: the actor checks whether the SII has published newer lists than its snapshot and, if so, streams the live SII files for your lookup automatically.
• Any RUT format in, clean structured JSON/CSV/Excel out. Not-found and invalid RUTs still return a record, so your input and output lists line up.

Input

Lookup mode (default)

{
  "mode": "lookup",
  "ruts": ["90.749.000-9", "93834000-5", "61.704.000-K", "968069802", "76086428"]
}

Accepted formats: 76.123.456-7, 76123456-7, 761234567 (last digit = DV), 61704000K, or the number alone (76123456, DV computed for you). Several RUTs on one line separated by spaces, commas or semicolons also work. Up to 100,000 RUTs per run; duplicates are returned once.

Every input RUT produces one record with a status:

status	meaning
found	company found (found: true)
not_found	valid company-range RUT that is not in the SII legal-entity list or the company registry
invalid_dv	the check digit does not match the number (the correct DV is shown in dv)
invalid_format	not a RUT
natural_person_range	RUT below 45,000,000 — natural persons are never looked up

}

A company created through the online company registry also carries constitutionDate, initialCapitalClp and registryLegalForm (e.g. "2026-08-02", 5000000, "SpA"). Companies constituted after the latest SII list was published are returned from the registry alone (sources: ["COMPANY_REGISTRY"]).

The run also stores a SUMMARY record in the key-value store with counts per status, the filters used, the activity codes each keyword matched and the dates of the data snapshot.

Pricing

Pay per event — you only pay for companies actually returned:

Event	When
company-result	each company record with found: true (lookup or search)
Actor start	once per run (Apify's standard start event, a fraction of a cent)

From 30 October 2026, 1,000 companies found cost US$8 on the Apify Free plan; paid Apify plans pay less per company — see the Pricing tab for your plan's rate. Not-found, invalid and person-range RUTs are free. Platform compute is included. Set a maximum charge per run in Apify and the actor stops cleanly when it is reached.

Use cases

• KYB / supplier onboarding: validate a supplier's RUT and DV, legal name, activity and whether it has a término de giro before paying invoices.
• CRM and invoice data cleaning: normalize RUT formats, fix DVs and fill legal names, comunas and activity codes in bulk.
• B2B lead generation: list active software, construction or logistics companies in a comuna, filtered by size and number of employees.
• New-company monitoring: companies that started activities this month in your sector (startDateFrom + sortBy: newest).
• Market sizing and research: counts by activity, region and size bracket from the official SII classification.

FAQ

Where does the data come from? From the SII's public "Nóminas de personas jurídicas" (legal name, activities, addresses, company size) and the "Registro de Empresas y Sociedades" open dataset on datos.gob.cl. Both are published by the Chilean government for reuse.

How fresh is it? The SII updates its legal-entity lists about twice a year (latest: August 2026; size data is per commercial year, latest 2024). Each record shows dataAsOf. In the default auto mode, if the SII publishes newer lists than the actor's snapshot, lookups stream the live SII files (about 2 minutes instead of seconds).

Do you return data about people? No. Only legal entities are indexed, natural-person RUTs are rejected, and there are no fields about representatives, partners or owners. A company's legal name is returned exactly as registered; some company names (for example many EIRLs) include their founder's name. To leave out single-owner EIRLs in search mode, select the other entity types.

Can I check if a company is active? isActive is false when the SII has registered a término de giro (endDate). It reflects the SII list at dataAsOf.

What does employees mean? The number of dependent workers the company reported to the SII for the commercial year in sizeDataYear, counted at the head office (SII methodology). Companies without size data have null.

Why is a valid RUT not_found? It belongs to a natural person, to a taxpayer without legal personality, or to a company created after the latest published lists that is not in the online registry.

Is there an API? Yes — like every Apify actor you can call it via the Apify API, the JavaScript/Python clients, Make, Zapier or n8n, and export results to JSON, CSV or Excel. See Integrations below.

Is it legal to look up Chilean companies by RUT?

The actor only uses official open data that the SII and the Registro de Empresas y Sociedades publish for reuse on sii.cl and datos.gob.cl; it does not log in to any SII service. It covers legal entities only, rejects natural-person RUTs and has no fields about representatives, partners or owners. Some legal names (for example many EIRLs) contain a founder's name, so Chile's Ley 19.628 and the new Ley 21.719 on personal data, and the EU GDPR if you work with EU data, can still apply to how you use the results; you are responsible for a lawful purpose such as KYB, invoicing or B2B research. Respect the terms of the original data sources. This is general information, not legal advice.

Integrations

Call the Chile Company RUT Lookup from the Apify API or the JavaScript and Python clients (it works well as a validation step inside an ERP, CRM or invoicing flow), trigger follow-ups with webhooks, or schedule a monthly "new companies" search in Apify Console. It works with n8n, Make and Zapier, and with LangChain and LlamaIndex through their Apify integrations. AI agents in Claude, ChatGPT, Cursor and other MCP clients can find and run it through Apify's MCP server. Export as JSON, CSV or Excel, or read from the dataset API.

Use with AI agents

Use this actor to validate Chilean RUTs and get official SII data for companies (legal name, entity type, activities, address, size, start and termination dates), or to search companies by name, activity, comuna, region, size and start date.

{ "mode": "lookup", "ruts": ["76.086.428-5", "96806980-2"] }

Main output fields: rutFormatted, found, status, legalName, entityType, isActive, startDate, endDate, primaryActivity, activities, address, comuna, region, companySize, employees, dataAsOf. It is pay-per-event: an agent pays a small start fee plus a fixed price per company found; not-found and invalid RUTs are free.
