About RUT (Chile)

What is RUT?

RUT (Rol Único Tributario) is Chile's fiscal and personal identifier, issued by SII. It has 7-8 digits followed by a check digit (0-9 or K), in XX.XXX.XXX-D format.

Verification algorithm

The check digit is calculated by multiplying base digits (right to left) by weights 2, 3, 4, 5, 6, 7 (repeating), summing products, dividing by 11, and subtracting remainder from 11. Remainder 0 gives 0, remainder 1 gives K.

Use in development

Systems for the Chilean market — banks, e-commerce, government platforms — require RUT as mandatory identification. The generator creates fictitious RUTs with correct check digits.
