How this service works
Live EU VIES check: is this VAT number registered, and under what name. Member state outages give UNVERIFIED.
Output
Returns a JSON object with: `valid` (boolean or null), `verdict` (string summary), `name` (registered business name), `address` (registered address), `country` (ISO country code), `number` (normalized VAT number), `localFormat` (country-specific format), `asOf` / `requestDate` (timestamp of the VIES response), `degraded` (true if a member state system was unavailable), `reasons` (array of explanation strings), `summary` (human-readable summary), `source` and `sourceUrl` (VIES attribution), and `disclaimer`. If the member state system is down, `degraded` is true and the verdict may be UNVERIFIED.
Example use cases
Supplier onboarding VAT check
“Before we add this new supplier to our system, can you verify their VAT number DE123456789 against VIES to confirm it's valid and get the registered company name?”
Invoice validation before payment
“We just received an invoice from a company claiming VAT number FR12345678901 — can you check if that's a real, active EU VAT registration and what name it's registered to?”
B2B customer eligibility for zero-rating
“This customer says they're VAT-registered and gave us NL854695410B01 — can you confirm it's valid in VIES so we can apply zero-rate VAT on their order?”
Technical details
Endpoint
GEThttps://bank-validators.x402tookit.com/eu-vat-vies?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a live, real-time check against the official EU VIES registry — not just format validation. It is the right choice when you need to confirm a business is actively VAT-registered and retrieve their official registered name and address for invoicing, compliance, or onboarding purposes. Prefer it over offline format-only validators when the authoritative answer matters and you can tolerate occasional UNVERIFIED results due to member state outages.
Side effects
- Member state VIES system unavailable — returns degraded:true with UNVERIFIED verdict rather than valid/invalid
- Invalid VAT number format — may return valid:false with reasons explaining the format issue
- VAT number not found in VIES — returns valid:false
- Missing country prefix or incorrect prefix (e.g. EL for Greece, not GR) — query may fail or return unexpected results
- Network timeout to VIES backend — may return null fields with error reasons
