EU 27 + UK
VAT number validator
Enter a country and VAT number to validate against the European Commission's VIES system (for EU member states) or HMRC's VAT checker (for GB-prefix numbers). We never store your input. Validation is performed live against the official service when you submit.
How validation works
- For EU 27 numbers: we POST to VIES, the European Commission's free VAT-number validation service. VIES returns valid / invalid and (depending on member state) trader name and address.
- For GB-prefix numbers: we call HMRC's UK VAT check service. Since Brexit, VIES no longer covers GB numbers.
- VIES has rate limits and occasional outages. If the service is unavailable we return an explicit "service unavailable" state rather than guessing.
- VIES confirms registration for intra-EU trade. It does not confirm trading status, financial standing, or fitness for any particular contract.
