Informational only
This tool checks VAT IDs against VIES. VIES can be slow or temporarily unavailable.
- A “valid” result is not a guarantee of tax treatment — always keep evidence and follow invoice rules.
- VAT IDs are business identifiers — avoid sharing them unnecessarily.

Frequently Asked Questions
What is VIES?+
VIES is the European Commission's VAT Information Exchange System for validating EU VAT registration numbers. Availability can vary by member state.
Why should I validate an EU VAT number?+
Validation can help establish that your customer is a taxable business for certain EU B2B scenarios. Keep evidence (timestamp, result, and customer details) alongside your invoice records when you rely on it.
What if VIES is down or slow?+
Try again later. VIES can be temporarily unavailable. A temporary failure does not necessarily mean a VAT number is invalid.
Does "valid" guarantee reverse charge VAT applies?+
No. VAT treatment depends on the specific transaction and local rules. Validation is one piece of evidence; it does not determine invoice requirements by itself.
Does Gruv support VAT validation workflows?+
In supported workflows, Gruv can treat VAT validation as a KYB/compliance signal and keep an audit trail for ops and invoicing.
Is this tax or legal advice?+
No. This tool is informational only and is not tax or legal advice.
