EU VAT Number Validator

Validate EU VAT IDs against VIES and keep evidence for invoices. Free and private — informational only.

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.

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.

Is this tax or legal advice?

No. This tool is informational only and is not tax or legal advice.
