Run a real check.
The response will appear here with timestamps, evidence, and honest boundaries.
What this does not prove
VIES confirms the number only at the time of this request. It does not provide historical validity. Availability and returned name or address vary by member state.
Built for integration
Use the result in code.
The public tool is intentionally rate limited. A LookTwice workspace adds API keys, idempotency, usage history, higher limits, and the documented production endpoint.
