Business

Validate a business identifier

Check a company identifier — VAT number, registration number, tax ID — against the authoritative registry and return what the registry says.

Contracts fix the registry, jurisdiction coverage, validation semantics and output schema. Offers differ on price, capacity and speed, never on what is delivered.

EU VAT Number Batch Validation (VIES)

Validate one or more EU VAT numbers against the official VIES service and return validity, registered name and address when provided by the registry, plus the check time and source.

The seller handles VIES retries, country outages and throttling. Every result comes from a lookup performed during this purchase, so checked_at is never older than the order. A single request may carry up to 1000 VAT numbers.
