How this service works
Check an EU VAT number live against the European Commission's VIES system: valid or not, and the registered company name and address where the member state shares them. Northern Ireland (XI) numbers included. Sole traders' names are withheld (personal data).
Output
A JSON object containing: 'valid' (boolean), 'vatNumber' (the queried number), 'country' (2-letter country code), 'name' (registered company name or null), 'address' (registered address or null), 'withheld' (boolean, true if name was hidden for sole-trader privacy), 'source' (e.g. 'EU VIES'), and 'checkedAt' (ISO 8601 timestamp of the live check).
Example use cases
Supplier invoice VAT check
“Before I pay this invoice, can you verify that the VAT number DE811569869 on it is actually valid and tell me what company name is registered against it?”
New customer onboarding KYB
“We're onboarding a new B2B customer in France — their VAT number is FR12345678901. Can you confirm it's active in VIES and give me the official registered name and address?”
Northern Ireland VAT compliance
“I need to verify a Northern Ireland VAT number for a supplier — it's XI123456789. Is it registered and valid, and does VIES show a company name for it?”
Technical details
Endpoint
GEThttps://aayatai.com/eu/vat?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a live, authoritative check of an EU or Northern Ireland VAT number against the official VIES system — not a cached or third-party database. Prefer it for compliance workflows, supplier onboarding, invoice verification, or any context where real-time validity and official registered details matter. It is the right choice when you need the actual registered company name and address (where the member state shares them), not just a format check.
Side effects
- VAT number format is invalid or missing country prefix — returns error or invalid result
- VIES system temporarily unavailable — upstream timeout or service disruption
- Member state does not share name/address — valid=true but name and address are null
- Sole trader VAT number — valid=true but name withheld, withheld=true
- Country code not in EU/XI — unsupported country prefix returns error
