Seller contact phone number is missing

BR-DE-6 comes from the official e-invoicing rule sets. This page explains what the rule checks, why invoices trip over it and the concrete change that makes the document pass.

Applies to: XRechnung

Related fields: BT-42

Why this error appears

Part of the XRechnung seller contact requirement: the contact telephone number (BT-42) is mandatory alongside name and email. Systems that only store an email address for the billing contact trip over this one.

How to fix it

Provide the seller contact telephone number (BT-42).
