LIVE EU VAT number validation against VIES, the European Commission's official service — not a format check: the number is verified in the member state's actual register, returning the registered trader name and address where published. Covers all 27 member states plus Northern Ireland (XI). Essential before B2B invoicing with reverse charge.
