More about BR-DE-6

XRechnung requires a telephone number for the seller contact, so the buyer's accounts department can resolve questions quickly. The format is free text, but international format is the safest choice: +49 30 1234567.

A general office number is fine; it doesn't have to be a direct line. If you'd rather not publish a mobile number, a landline or a virtual number works just as well.
