Checking an EU supplier's stated VAT number and saving the dated validation response as one identity and invoicing control
What the source establishes.
VIES is the European Commission's online VAT Information Exchange System interface for querying national VAT databases to determine whether a submitted number is valid for intra-EU cross-border trade at the time of the request.
The linked record system is maintained by the organization responsible for the certificates, approvals, or program records it exposes.
What this record does not prove.
A valid VAT number is not proof of manufacturing capability, facility ownership, authorized bank instructions, product origin, tax advice, quality, capacity, certification, labor conditions, or delivery; names and addresses may not be returned for every country, and temporary database outages occur.
A reachable official source can verify identity, stated scope, and access. It cannot silently become an audit of workmanship, delivery, labor conditions, or suitability for your project.
A record that can age in public.
New checks are appended rather than replacing earlier states. The latest source review is due by October 13, 2026.
