How this service works
Live intra-EU VAT number validation via the European Commission VIES REST API (real-time query of the member state registry). Query: ?cc=IE&vat=6388047V (cc = member state code incl. EL/XI, vat = number without country prefix). Returns is_valid, the trader name and address as registered (when the member state publishes them) and request_date (compliance timestamp); 24h cache.
Output
Returns a JSON object with is_valid (boolean indicating whether the VAT number is registered and active), request_date (timestamp of the check for compliance record-keeping), and user_error (any error message from the member state registry). Results are cached for 24 hours.
Example use cases
Example prompt
“Can you check whether this Irish VAT number is valid — member state IE, number 6388047V — I need to confirm before we issue an invoice?”
Technical details
Endpoint
GEThttps://data.greeneris.io/v1/eu/vat-checkWhen to prefer
Use this endpoint when you need real-time EU VAT number validation backed by the official European Commission VIES registry, especially for B2B invoicing compliance, supplier onboarding, or intra-EU transactions. Prefer over manual checks or third-party scrapers when you need an authoritative compliance timestamp. Best for single VAT lookups across all EU member states including EL (Greece) and XI (Northern Ireland).
Side effects
- Invalid or unsupported member state code returns an error
- VAT number format mismatch for the given country may trigger user_error
- Member state registry temporarily unavailable may return error or stale cache
- Missing required query parameters cc or vat returns a bad request error
- Non-EU or unsupported country code returns an error
