How this service works
Single live pass-through call to the EU Commission's VIES (VAT Information Exchange System) confirming whether an EU VAT registration number is currently valid, with registered name/address when available. Every call is a real-time confirmation only -- never a cached, stored, or aggregated result -- matching VIES's own stated purpose (real-time confirmation of VAT number validity per Council Regulation (EC) No. 904/2010) and how existing commercial VIES-based products already operate.
Output
Returns the real-time VIES validation result for the submitted EU VAT number, including a boolean validity flag and, where the member state exposes it, the registered legal name and address of the VAT-registered entity. Results are live confirmations from VIES at the moment of the call — never cached or stored.
Example use cases
B2B invoice VAT verification
“Before I issue this zero-rated invoice to our German client, can you verify that their VAT number DE987654321 is currently valid in VIES and give me their registered company name?”
Supplier onboarding compliance check
“We're onboarding a new supplier from France — their VAT number is FR12345678901. Can you confirm it's actively registered in the EU VIES system and pull their official registered address?”
Automated checkout tax exemption check
“A business customer just entered VAT number NL854567678B01 at checkout to claim B2B tax exemption — can you do a live VIES check to confirm it's valid before I remove the VAT from their order?”
Technical details
Endpoint
POSThttps://api.macaroonnetwork.com/execute/vat-validate-v1When to prefer
Use this endpoint when you need a real-time, authoritative confirmation of an EU VAT number's validity directly from the VIES system — not a cached or third-party-stored result. Ideal for B2B invoicing workflows, supplier onboarding, e-commerce tax exemption checks, and any compliance scenario where you need a live VIES confirmation at the moment of the transaction. Prefer this over cached VAT databases when regulatory or audit requirements demand current-state verification.
Side effects
- VIES system temporarily unavailable or returning service errors (EU member state systems go offline periodically)
- VAT number format invalid for the specified country (malformed input)
- Member state does not expose name/address data — valid result returned but name/address fields are blank
- Rate limiting or timeout from the upstream VIES API
- Invalid or unrecognised country code prefix in the VAT number
