Explanation
The VAT identifiers of seller (BT-31), tax representative (BT-63), and buyer (BT-48) must start with an ISO 3166-1 alpha-2 country prefix — e.g., 'DE123456789' rather than just '123456789'. Greece uses 'EL' instead of 'GR' as an exception.
How to fix
Prefix VAT identifiers with the correct country code.
This field is required by §14 Abs. 4 Nr. 2 UStG. A missing or incorrect value may affect input VAT deduction (Vorsteuerabzug) for the recipient.
