VIES VAT Validation + Claude
Validate EU VAT numbers via the European Commission VIES (VAT Information Exchange System) REST API. Confirms that a VAT number is registered for intra-Community trade and returns the trader name and address when the member state exposes them.
Prerequisites
See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:
(none — public API)
Step 1 — Get credentials
Use for B2B invoice compliance: before issuing an intra-EU invoice without VAT, confirm the buyer's VAT number is valid via this adapter.
Country codes: ISO 3166-1 alpha-2, plus EL for Greece and XI for Northern Ireland. Common codes: DE, AT, FR, IT, ES, NL, BE, PL, DK, SE, FI, IE, PT, CZ, HU, RO.
Format: VAT number must NOT include the country code prefix (e.g. for DE123456789 pass countryCode='DE' and vatNumber='123456789').
Response: valid: true/false, plus name and address when provided by the member state. Some countries (DE, ES) do not return name/address for privacy reasons — in that case only valid is authoritative.
