How is the Commercial RUT validated?
The RUT is the tax registration record managed by DIAN in Colombia. The commercial version requires the NIT taxpayer ID together with a valid 4-digit economic activity code (CIIU).
This tool generates and validates commercial RUTs, checking NIT Modulo 11 check digits and verify alignment with economic activity classification.
