Official rule text
Das Element "Seller post code" (BT-38) muss übermittelt werden.
Why it happens
Same as the city: the post code sits inside a combined address line and is never populated as its own field on export.
How to fix it
Send the post code in BT-38: cac:PostalAddress/cbc:PostalZone in UBL, ram:PostalTradeAddress/ram:PostcodeCode in CII.
