VAT Validator
Verify EU VAT numbers and resolve to the registered company name and address. Useful for B2B billing operations and pre-contract sanity checks across the Atlantic.
Why this exists
When you onboard an EU customer or sign a vendor contract across the Atlantic, the VAT number on the paperwork has to actually be valid. If it isn't, your invoice is non-compliant and your tax office may reject it. Most finance teams paste the number into the European Commission's VIES portal once the contract is already signed. That's the wrong order.
This tool is the same VIES check, run before the contract instead of after. Country prefix, VAT number, submit — you get the registered company name back if it's valid, or a clear "no match" if it isn't.
Frequently asked questions
What does VAT Validator do?
Validates EU VAT numbers via VIES (the European Commission's official VAT verification service) and returns the registered company name + address when the VAT number is currently valid. Confirms a counterparty's tax status before generating a B2B invoice.
Why does VAT validation matter for billing?
B2B invoices to EU counterparties typically require a valid VAT number to apply the reverse-charge mechanism (zero-rate VAT). Issuing an invoice with an invalid VAT can leave you liable for the standard-rate tax. VIES is the canonical real-time check.
Does this cover non-EU VAT?
No — VIES is EU-only. UK VAT (post-Brexit) requires HMRC's separate API. Switzerland, Norway, and other non-EU European VAT jurisdictions have their own registers. This tool covers the 27 EU member states.
