VAT identification number

Businesses which intend to participate in intra-Community trade operations, that is to deliver or acquire goods within the European Union territory, require what is called a VAT identification number (USt-IdNr.). The identification number consists of a country code and a combination of letters and numbers including up to 12 characters.

More information on this isse is provided by the Bundeszentralamt für Steuern (Federal Central Tax Office) on the internet at

From January 1, 2022, it is mandatory to provide the Value Added Tax Identification Number (VAT ID) of the trading partner in the direction of dispatch!

Enter the Value Added Tax Identification Number (VAT ID) of the trading partner in the Member State of destination.

In the case of an intra-Community triangular transaction (the German company is the first supplier), the VAT ID of the consignee of the commodity in the country of destination must be entered (recording of the physical movement of goods). If this is not known, the country code of the country of the invoice recipient must be entered in combination with a fictitious series of twelve times the digit "9" (e.g. FR999999999999).

For this reason the VAT ID differs from the code of the Member State of destination.


More information about the Value Added Tax Identification Number you will find in the documentation "Explanations to changes to reporting obligations for ITGS from 2022".  

Explanations of the structure of the VAT ID number are available in the documentation on the structure of the sales tax identification number in the EU member states.
