 FAQ

What is a VAT number and why do businesses need one?

A VAT (Value Added Tax) number is a unique identifier assigned to businesses registered for VAT in European countries. It is required for cross-border trade within the EU, allowing businesses to charge and reclaim VAT correctly and comply with tax regulations.
Why do different EU countries have different VAT number formats?

Each EU member state designed its own VAT numbering system independently before the EU harmonised the prefix requirement. The local formats vary in length and structure because they are tied to each country existing national tax identification systems and administrative traditions.
