Chile RUT check

Q: Can I check RUTs from code or in bulk?

Yes. The same check is available over the REST API (GET /v1/cl/rut/{id}) and the MCP server, with the same key as every other country. See the API docs.

Check a Chile RUT against the official registry and get the legal name, the status and a pass, review or fail verdict. Official registry

Example: 61.704.000-K (Codelco). No account needed: 10 lookups a day per network, shared with the keyless API.

What this check tells you

Official registry

For RUT we first check the structure and check digit, then look the number up in SII – Servicio de Impuestos Internos, Nómina de personas jurídicas (razón social) (periodic copy). The answer gives the legal name and the registry status, and a pass, review or fail verdict with reasons. Every answer carries source.data_as_of.

Businesses run by one person get their status only, never a name or address.

Chile ID formats we check

ID type	Level	Check digit	API endpoint	Official lookup
RUT Rol Único Tributario (RUT)	Official registry	Mod 11 with weights 2-7 (K = 10)	`GET /v1/cl/rut/{id}`	SII: consultar situación tributaria de terceros

From code

Same key and quota as every other country. A well-formed request costs one lookup; a source that does not answer returns HTTP 503 and is not counted.

curl "https://taxid.halpii.com/v1/cl/rut/61.704.000-K" \
  -H "Authorization: Bearer $KEY"

Questions

Only the registry lookup tells you that. A number that passes the format check is then looked up in SII – Servicio de Impuestos Internos, Nómina de personas jurídicas (razón social); the answer says whether it was found and its status.

Where does the data come from?

From SII – Servicio de Impuestos Internos, Nómina de personas jurídicas (razón social) (periodic copy). Each answer includes the source and the date of the data.
