About this Validator

This tool validates Belgian Enterprise Numbers (Ondernemingsnummer/Numéro d'entreprise) which also serve as VAT numbers (BTW/TVA/NWSt).

The validator checks if a given number follows the correct structure and verifies the check digits using the official algorithm.

This validation only confirms if a number follows the correct format. It does not verify if the number is actually registered with Belgian authorities.
