About this Validator
This tool validates Chilean RUT (Rol Único Tributario) and RUN (Rol Único Nacional) numbers according to official format requirements.
The validator checks if a given RUT/RUN follows the correct structure and verifies the check digit using the official algorithm.
This validation only confirms if a RUT/RUN follows the correct format. It does not verify if the number is actually registered with Chilean authorities.
