What a German VAT ID looks like

A German VAT ID (USt-IdNr) is commonly written as “DE” followed by 9 digits. It is used for EU VAT purposes and is distinct from the domestic Steuernummer and from commercial register references.

What VAT ID verification can and cannot do

VAT ID verification typically confirms whether a VAT ID is valid at the time of the check and can sometimes return limited matching information depending on the system and request type. It does not replace a commercial register extract when you need representation authority, register numbers, or registered seat confirmation.

Common pitfalls

Common problems include using an outdated VAT ID, confusing a Steuernummer with a VAT ID, or assuming VAT validity proves company registration status. In due diligence, use VAT checks and register extracts together for different layers of verification.

Good practice
