How this service works
Is this EU VAT number valid? Live VIES check against the European Commission's official VAT Information Exchange System — validate a European VAT id, verify a business tax id before invoicing, confirm B2B reverse-charge / zero-rating eligibility. Returns the registered trader name and address where the member state discloses them. Deterministic: no LLM. Distinguishes a genuinely invalid number from a member state whose system is merely offline, which VIES itself does not do cleanly.
Output
Returns whether the VAT number is genuinely valid or invalid, the registered trader's legal name and address (where disclosed by the member state), and a clear flag distinguishing an invalid number from a temporary member-state VIES system outage.
Example use cases
Example prompt
“Can you check if the EU VAT number DE345789012 is valid and tell me the registered business name and address — I need to confirm reverse-charge eligibility before I send an invoice?”
Technical details
Endpoint
GEThttps://compliancepulse.theaslangroupllc.com/api/validate/vat?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a live, authoritative EU VAT validation directly from the European Commission's VIES system — especially when you must distinguish a truly invalid VAT number from a member-state outage, or when you need the registered trader name and address for invoicing. Prefer this over self-built regex checks or indirect lookups when B2B reverse-charge zero-rating compliance is at stake.
Side effects
- Invalid VAT format — number doesn't conform to the country prefix and checksum rules
- Member state VIES system offline — endpoint explicitly flags this as a connectivity issue rather than invalidity
- Unknown or unsupported country code prefix
- Rate limit or payment failure — $0.01 USDC per call, payment must succeed
- VAT number valid but member state withholds trader name/address (common for some countries)
