EU VAT number checker

Validate a customer's EU VAT number against VIES before you zero-rate a supply. VIES is not one register but twenty-seven — it forwards the question to the member state that issued the number, so an unanswered check usually means that country's system is down rather than an invalid number.

• Zero-rating an intra-EU supply depends on a valid number; if it is invalid the tax is yours
• Germany and Spain confirm validity without publishing a name or address
• A GB number is not on VIES — the UK left it. Northern Ireland XI numbers still are
