What it means
Every invoice must contain the buyer's postcode (BT-53). XRechnung requires the postcode in the buyer's address.
Why it matters
XRechnung, the German standard for e-invoices, requires this on top of EN 16931. Public bodies in Germany and their invoice portals (ZRE, OZG-RE and the state portals) reject an XRechnung that fails this rule, and many German businesses check incoming invoices the same way.
How to fix it
Complete the customer's address with the postcode on the customer record in your invoicing software and export again.
The rule as published
Das Element "Buyer post code" (BT-53) muss übermittelt werden. Business terms: BT-53
