For sole proprietorships in Germany, the VAT number is generally issued to the private name and address. However, if you are sole trader and would like to register the company and the business premises so that SONNENTOR (and other EU suppliers) can issue the invoice accordingly, there is the option of registering a euro address with the Federal Central Tax Office. This option is also listed on the notification from the BZS about the assignment of the UID number.
The entry of the euro address must be applied for in writing to:
Federal Ministry of Finance
Saarlouis office
66738 Saarlouis
Fax: + 49 228-406-3801
Phone: +49 228 406-1222
If you have any further questions on this topic, we recommend that you take a look at the FAQ from the Federal Central Tax Office.
