VIES VAT Checker

Verify European VAT numbers

What is VIES?

VIES (VAT Information Exchange System) is the European Commission's official system for checking the validity of VAT numbers in the European Union. The system allows traders to verify whether their partners are VAT registered in another member state.

Why use VIES?

Checking VAT numbers is mandatory for intra-community supplies and services. If your counterparty is not VAT registered in VIES, there may be issues with the tax treatment of the transaction. Using VIES helps you to:

Confirm the validity of your partners' VAT numbers
Avoid tax issues with cross-border transactions
Verify counterparty details before entering into a contract
Fulfill your obligations under VAT legislation
