BR-DE-9 — E-Invoice Validation Rule & Fix

Fixture ID: noAddressParts · XPath: /ubl:Invoice/cac:AccountingCustomerParty/cac:Party/cac:PostalAddress/cbc:PostalZone

1. Why This Rule Triggers (Diagnostic Message)

XRechnung requires the element "Buyer post code" (BT-53). Core EN 16931 only requires the country code, but the German CIUS additionally makes city and post code mandatory on both parties so that the address is deliverable, not merely jurisdictional.

2. How to Fix BR-DE-9

Set buyer.address.postalCode.

3. Valid Code / Payload Example

"postalCode": "10115"
