What is a VAT Number?

Updated on June 28, 2022

For the purposes of value-added tax, a Value-Added Tax Identification Number (VATIN) is an identifying number commonly used.

In the European Union, a VAT Identification Number can be verified online at the official EU VAT Information Exchange System (VIES) website. You can use this website to confirm that the number is currently valid and to view the name or other identifying details of the organization that was assigned the number.
