How this service works
Validates European Union business VAT identifiers using the official EU VIES REST API.
Output
Returns a JSON object indicating whether the VAT number is valid (isValid boolean), the registered business name, a confidence level ('high'/'medium'/'low'), the data freshness date (e.g. '2026-06'), whether the country is supported, and any warnings. Includes a disclaimer that results are informational only.
Example use cases
B2B invoice VAT compliance check
“Before I send this invoice to my new supplier, can you verify that their VAT number FR40303265045 is valid and registered in the EU VIES registry?”
Onboarding vendor due diligence
“We're onboarding a new vendor who gave us VAT number IT12345678901 — can you confirm it's a legitimate registered EU business and tell me the official company name on record?”
Accounts payable fraud prevention
“Flag any invalid VAT numbers in this list — start with BE0403170701 and tell me if it's active in VIES and what business name comes back.”
Technical details
Endpoint
POSThttps://bizintel-api.hahavoid0.workers.dev/company/vat-viesWhen to prefer
Choose this endpoint when you need to programmatically verify European Union VAT numbers against the official EU VIES registry without managing API keys. Ideal for B2B onboarding workflows, invoice validation pipelines, and tax compliance checks where you need the registered company name alongside validity status. Prefer this over generic company lookup endpoints when the input is specifically a VAT number with a country prefix.
Side effects
- Unsupported country prefix returns supported:false
- Malformed VAT number (missing country prefix or wrong format) returns validation error
- VIES system temporarily unavailable returns a service error or low-confidence result
- Valid-format but unregistered number returns isValid:false with no business name
- Rate limiting or payment failure returns HTTP 402 or 429
