About this Validator
This tool validates Swiss Business Identification Numbers according to official requirements.
The validator checks if a given UID follows the correct structure and verifies its check digit using the Modulo 11 algorithm.
This validation only confirms if a number follows the correct format. It does not verify if the number is actually registered with Swiss authorities.
