EU VAT Validator

EU VAT validator class. Enter valid EU VAT number and click "Validate".

Note, that provided validation is not sufficient and does NOT guarantee that the verified VAT number really exists. For that purpose you can use online service ie. VAT checker or VIES VAT number validation. For automated verification are available paid services, such as viesapi.eu.

Example: valid EU VAT numbers are e.g. ATU99999999 or LU12345678
