Frequently Asked Questions
Answers to the most important questions about the Northern Irish VAT ID.
What terms are used for the Northern Irish VAT ID?
The Northern Irish VAT identification number is known by several names: VAT ID, XI VAT Number, Northern Ireland VAT, UK VAT NI, Windsor Framework VAT, XI VAT. Also referred to as VAT number XI or Northern Ireland VAT ID. All terms refer to the same number registered in the EU VIES system.
What is the difference between VAT ID, tax number (Steuernummer) and MwSt number?
The VAT ID (also known as USt-IdNr., UID, UStID, MwSt-Nummer, VAT Number) is the VAT identification number for the EU single market — with country code (XI) and verifiable via the VIES system. The tax number (Steuernummer) is a purely national identifier issued by the local tax office and has no relevance for cross-border trade. "Umsatzsteuer-Nummer" is often used synonymously but technically means the VAT ID. The terms "MwSt-Nummer" and "Mehrwertsteuer-Nummer" refer to the same number — only the label differs.
