VIES Validation: The Gold Standard

A VAT number is just a string of characters until it is validated. The EU Commission's VIES (VAT Information Exchange System) is the only source of truth. We query it live.

Real-Time VIES Checks

When we pull a VAT number for a seller, we don't just store it. We run a live query against the VIES API to confirm the number is currently active. A number might have been valid last year but deregistered today. Old data puts you at risk.

Why Accurate VAT Data Matters

For B2B transactions, you need to know if you can reverse-charge VAT. For compliance providers, identifying invalid VAT numbers is a lead generation goldmine. It allows you to approach a seller with "Your VAT number is invalid, let us fix it."
