Check VAT number

Validate European VAT and UID numbers through the official VIES database and see whether the number is currently confirmed as valid.

VAT validation is performed through the European Commission VIES service. Some countries return limited company details.

Validate VAT IDs before invoicing

A quick VAT number check helps you spot invalid or mistyped VAT IDs before they end up on invoices, customer records, or accounting exports.

The validator normalizes the entered number, splits country code and national VAT number, and queries the European Commission VIES service for the official validation result.

What the VAT check includes

  • Format and EU country code normalization
  • Validation through the official VIES service
  • Validity status and request details
  • Available company name and address information where provided by the member state

Questions about VAT number checks

What is a VAT number?

A VAT number identifies a taxable business or legal entity for value added tax purposes. In Austria and Germany it is often referred to as a UID or Umsatzsteuer-Identifikationsnummer.

Does every country return company details?

No. VIES can confirm whether a VAT number is valid, but available name and address details depend on the member state that issued the number.

Does a valid VIES result guarantee tax compliance?

No. The result is a technical validation of the VAT number at the time of the request. Accounting and tax decisions should still follow your local compliance process.
