What Is a VAT Number?

Andrew L. Carstone Author

A VAT number is a tax registration identifier used in value-added tax systems. It identifies a business that is registered to charge, collect, or report VAT within a specific jurisdiction.

A VAT number is not the same as a company registration number or a business license. It specifically relates to participation in a VAT system and is used in tax reporting and invoicing.
