Frequently asked questions
Is the VAT validator free?
Yes — 5 free checks per day per IP, no signup. Beyond that, use the DeFi Intel Agent Gateway API (pay-per-use) or a prepaid API key.
Where does the data come from?
The check queries the VIES (VAT Information Exchange System) registry, the authoritative EU source for VAT validity.
What output do I get?
Whether the number is valid, the country, and the registered name and address where publicly available.
What if VIES is unavailable?
VIES can be temporarily unavailable at night or during maintenance — if so, the tool will report that the registry could not be reached.
