# What is the EU VAT Number?

A European VAT number is a registered tax identification used to track how much tax business pays and collects through purchases and sales (expenses and revenue). 

Carbone Account billing system accepts only EU VAT numbers from European businesses (FR, UK, DE, etc...)

**Important note:** This is not the same as a local tax number or tax ID.
