Frequently Asked Questions
Answers to the most important questions about the Austrian VAT ID.
What terms are used for the Austrian VAT ID?
The Austrian VAT identification number is known by several names: VAT ID, UID Number, ATU Number, Austrian VAT, UStID, Umsatzsteuer ID. Also referred to as VAT number AT or Austria 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 (AT) 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.
What is the format of an Austrian VAT ID?
