Check an EU VAT number with the European Commission's VIES service: valid or not, with the registered name where the country publishes it. Inputs: country (two-letter code, e.g. IE, DE, FR; Greece is EL) and number (without the country prefix). If the country's own VAT system is down, the first rule fails -- try again later.
