About this Validator
This tool validates German VAT Numbers according to EU and German tax authority requirements.
The validator checks if a given VAT number follows the correct structure and verifies its check digit using ISO 7064 Mod 11,10.
This validation only confirms if a VAT number follows the correct format. It does not verify if the number is actually registered with German tax authorities.
