caf_belongs_to_another_empresa

The CAF’s <RE> names a different RUT than the empresa it was uploaded to.

What to do

The SII issues a CAF to one emisor. Every document drawn from another empresa’s range is rejected — after the folio is already spent. Check you downloaded the file under the right RUT.

The envelope

  "error": {
    "type": "unprocessable_error",
    "code": "caf_belongs_to_another_empresa",
    "message": "…",
    "hint": "The SII issues a CAF to one emisor. Every document drawn from another empresa’s range is rejected — after the folio is already spent. Check you downloaded the file under the right RUT.",
    "retriable": false,

}

Program against code, never against message — the prose can be rewritten, the code cannot (§5.8).

hint and retriable arrive in the response with these exact values: they are a function of code and come from the same dictionary GET /v1/error_codes serves, so the envelope and the dictionary cannot disagree. Both are English on the wire by design — one registry, one language. More in The error envelope.
