RUT Utils

Rol Único Tributario (RUT)

Each person registered in the database of the Civil Registry has its own RUT, that is unique and unrepeatable number that useful as a method of identification. This consists of an 8-digit number with a verification digit that can be from 0 to 9 or a K.


The utilities for the use of the RUT number, consist in a set of tools that allow you to verify the validity of the number, give it a format, and obtain the full name and aditional information of a person that is linked to that Rut number.


  • Give Format a RUT
  • Clean the invalids characters RUT
  • Calculate the verifier digit
  • Verify if its a valid or invalid RUT
  • Get the number of 8 digits or the verifier digit from the RUT
  • Get the full name and additional information of a person from the RUT
