CL_RUT — Rol Único Tributario / Rol Único Nacional

Overview

Universal personal + tax identifier. Naturales receive a RUN from the Servicio de Registro Civil; jurídicas receive a RUT from the Servicio de Impuestos Internos. Both share the same number space and validation algorithm — nationid exposes them as a single document type.

• Issuer: Servicio de Impuestos Internos (jurídicas) and Registro Civil (naturales)
• Source: https://www.sii.cl/
• Visual format: 12.345.678-5 or 8.765.432-K with thousands separators
• Legal basis: DFL 3/1969

Algorithm

mod-11 with cyclic weights 2, 3, 4, 5, 6, 7 applied right-to-left.

weights = cycle [2, 3, 4, 5, 6, 7]  applied right-to-left over the base digits
sum     = sum(digit_i * weight_i)
r       = sum mod 11
dv      = 11 - r

if dv == 11: '0'
if dv == 10: 'K'
otherwise:    str(dv)

Notes

• The DV K is case-insensitive in input but normalized to uppercase K in output
• All-same-digit sequences pass the checksum but are accepted by SII without restriction (different from BR CPF convention)

CL_PASAPORTE — Pasaporte

Overview

Travel document issued by the Servicio de Registro Civil e Identificación (SRCeI). Until Aug 2013 the passport number equaled the holder's RUN; since then numbers are unique and independent of RUN. Current samples are 8-9 alphanumeric chars.

• Issuer: SRCeI — https://www.registrocivil.cl/
• Composition: 8-9 alphanumeric
• Visual format: contiguous chars

Algorithm

None on the printed number. MRZ check digit lives in algorithms/icao-9303.ts.

Confidence

low — no SRCeI public format spec.
