How this service works
Validate an EU VAT number against the European Commission VIES registry, returning validity and the registered trader where the member state discloses it.
Output
Returns whether the VAT number is valid (true/false), the queried VAT number, the member state, and where the country discloses it: the registered trader's name and address.
Example use cases
Supplier due diligence before payment
“Before I pay this invoice, can you verify that VAT number NL123456789B01 is a legitimate registered business in the Netherlands?”
B2B customer onboarding check
“We just got a new customer claiming to be VAT-registered in France with number FR40303265045 — can you confirm it's valid and get the registered company name?”
Invoice compliance for EU zero-rating
“I need to zero-rate this sale to a German buyer — please verify their VAT number DE811569869 is active so I can apply the exemption correctly.”
Technical details
Endpoint
GEThttps://fittings.sh/v1/vat/eu-validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to verify EU business VAT registrations directly against the authoritative VIES registry — ideal for B2B invoicing compliance, supplier due diligence, EU reverse-charge VAT validation, or onboarding checks where you need both validity status and registered trader identity in a single call.
Side effects
- Invalid VAT number format returns a validation error or invalid status
- Member state systems temporarily unavailable (VIES can have per-country downtime) may return a service unavailable response
- Country code mismatch between vatNumber prefix and countryCode parameter causes an error
- Non-EU VAT numbers are not supported
- Rate limit or payment failure may block the request
