Sales tax ID number.


The sales tax ID number (abbreviated to USt-IdNr. in Germany and UID in Austria) is a unique EU wide code for entities that have to pay sales tax. Within the European single market it is used by fiscal authorities to account for sales tax.

Both a VAT number and a sales tax ID number are required to process EU customs clearances, triangular and series transactions in the EU. Your company has to be registered for sales tax with the Constance Office of Finance. Submit a written application for the issue of a sales tax ID number to the following address:

Finanzamt Konstanz
Sigismundstrasse 19
DE-78405 Constance

Tel. 0049 7531 289-0
Fax 0049 7531 289-312

In addition to the normal commercial information, the following information is needed for EU customs clearance: “Tax-free intra-community shipment as per §4 no. 1b and § 6a of the Sales Tax Law”.

The invoice must be drawn up without VAT if each party involved is entitled to sales tax relief – i.e. if they each have a sales tax ID number.
