It is only issued when you supply your own VAT as the requester (see below). - **Service status** - which member-state services are currently up. Official EU Commission (DG TAXUD) service. Reuse permitted with source acknowledgement; provided "as is", no SLA. Validation only - VIES is not a company registry. ## Authentication None. VIES is keyless and needs no registration.
