How this service works
Validação de número de VAT (IVA) europeu em tempo real (VIES, serviço oficial da União Europeia) — confirma se uma empresa da UE está registrada pra IVA antes de fechar negócio.
Output
Returns whether the given VAT number is valid and registered in the EU VIES system for the specified country, along with company registration details if available (such as registered name and address). Provides a real-time confirmation directly from the official EU VIES service.
Example use cases
Verify supplier VAT before payment
“Before I pay this German supplier, can you verify their VAT number DE123456789 is actually registered and valid in the EU?”
B2B onboarding VAT check
“We're onboarding a new French client who gave us VAT number FR40303265045 — can you check via VIES if that's a legitimate active VAT registration?”
Invoice compliance validation
“My accountant needs me to confirm the Spanish company we invoiced has a valid VAT number — it's ESB12345678. Can you look that up against the official EU registry?”
Technical details
Endpoint
GEThttps://agentum.lat/vat-validate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify whether a European business is legitimately VAT-registered before conducting B2B transactions, issuing invoices, or applying zero-rated VAT. It queries the official EU VIES system in real time, making it authoritative and suitable for compliance workflows. Prefer this over manual VIES web lookups or unofficial databases when automation or agent-driven due diligence is required.
Side effects
- Invalid or malformed VAT number format returns validation failure
- Country code not recognized or not an EU member state returns error
- VIES service temporarily unavailable (EU system downtime) may cause request failure
- VAT number exists but is currently inactive returns invalid status
- Missing required query parameters (country or vat) returns 400-level error
