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.
