Chile RUT Validator
Chile RUT / RUN Validator
Check the "Digito Verificador" of a Chilean ID.
About the Chile RUT Validator
The Chile RUT Validator is the definitive tool for checking the mathematical validity of a Rol Único Tributario (RUT) or Rol Único Nacional (RUN). In Chile, the RUT/RUN is used for everything from supermarket loyalty programs to signing legal documents and paying taxes through the SII (Servicio de Impuestos Internos). Our tool calculates the 'Dígito Verificador' (the letter or number after the dash) using the official modulo 11 algorithm. Protect your e-commerce platform and CRM systems from typos by instantly validating Chilean IDs directly in the browser.
Frequently Asked Questions
What does the K mean in a Chilean RUT?
When the modulo 11 checksum calculation results in a remainder of 10, the check digit is replaced with the letter 'K' to maintain a single-character suffix.
Can it format RUTs with dots and dashes?
Yes, the tool automatically cleans the input, strips out any dots or dashes you provide, validates the raw digits, and ignores formatting inconsistencies.
What is the difference between RUT and RUN?
RUN is assigned to individuals (citizens and residents), while RUT is assigned to legal entities and businesses. Structurally and mathematically, they share the exact same format and checksum algorithm.
