What does this mean?

The seller postal address (BG-5) must contain a country code (Seller country code, BT-40). The element is missing or empty.

Typical causes

The seller's country was not selected.
The country appears as a name in the city or an address line instead of as a code.

How to fix the error

Enter the two-letter ISO 3166-1 alpha-2 country code, e.g. DE for Germany or AT for Austria.
CII: ram:SellerTradeParty/ram:PostalTradeAddress/ram:CountryID, UBL: cac:AccountingSupplierParty/cac:Party/cac:PostalAddress/cac:Country/cbc:IdentificationCode.
Generate and validate the invoice again.

In E-Rechnungsfreund

In the invoice form, section "Verkäufer (BG-4)" (seller), select the country in the field "Land (BT-40/55)".

Example

Wrong

  <ram:LineOne>Musterstraße 1</ram:LineOne>
  <ram:CityName>Berlin, Germany</ram:CityName>
</ram:PostalTradeAddress>

Correct

<ram:PostalTradeAddress>
  <ram:PostcodeCode>10115</ram:PostcodeCode>
  <ram:LineOne>Musterstraße 1</ram:LineOne>
  <ram:CityName>Berlin</ram:CityName>
