How this service works
EU VAT number validation against the official VIES service: valid or invalid, registered name and address, an optional check of the name you expect and, if you give your own VAT number, a VIES consultation number to keep as audit evidence. Norwegian numbers are checked against the Norwegian VAT register. Use when: onboarding an EU supplier or customer, or before paying an invoice.
Output
Returns whether the VAT number is valid or invalid, the officially registered company name and address from VIES or the Norwegian register, whether the expected name matches (if provided), and a VIES consultation number (if a requester VAT number was supplied) for use as audit evidence.
Example use cases
Supplier onboarding VAT check
“We're onboarding a new Italian supplier who gave us VAT number IT12345678901. Can you validate it against VIES and confirm it's registered to 'Rossi Srl'? Use our VAT number DE987654321 so I have a consultation reference for the audit file.”
Invoice approval VAT verification
“Before I approve this invoice for payment, check that the French VAT number FR40303265045 is active and actually belongs to the company named 'Legrand SA'.”
Norwegian supplier VAT validation
“I need to verify that Norwegian VAT number 123456789MVA is valid and registered — we're about to sign a contract with them and need to confirm their tax status.”

Endpoint
POSThttps://agosint.shveik.dev/x402/vat?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, real-time EU or Norwegian VAT number validation with an optional audit-trail reference number. It is ideal for accounts payable automation, supplier onboarding workflows, and tax compliance where you need the official VIES consultation number as audit evidence. Prefer it over generic business lookup tools when the primary question is VAT registration status and compliance, not broader company information.
Side effects
- VIES service temporarily unavailable (EU system has scheduled downtime windows)
- VAT number format invalid or wrong country prefix
- VAT number not found in the register (may be newly registered or deregistered)
- Name match fails when company trades under a different registered name
- Norwegian VAT register unreachable
- Rate limiting or payment failure for the $0.015 USDC per-call fee
