BR-DE-9 requires the buyer postal address (BG-8) to contain the post code (BT-53). Together with BR-DE-8 (city), XRechnung makes the full buyer address mandatory.

Affected field
cac:AccountingCustomerParty/cac:Party/cac:PostalAddress/cbc:PostalZone (UBL) / ram:BuyerTradeParty/ram:PostalTradeAddress/ram:PostcodeCode (CII)
Cause
The buyer address has no post code field — common when only a routing ID (Leitweg-ID) was stored for a public buyer.
Fix
Add cbc:PostalZone with the post code under the buyer postal address.

Frequently asked questions
Is the Leitweg-ID enough instead of the address?▼
No. The Leitweg-ID (BT-10) routes the invoice but does not replace the postal address. XRechnung additionally requires the buyer's city (BT-52) and post code (BT-53).
