Set buyer.address.countryCode to the two-letter code, e.g. "DE" for Germany and "GR" for Greece — "GR" is the ISO 3166-1 code EN 16931 requires here, while "EL" is only the prefix Greek VAT identifiers (BT-31/BT-48) carry and is not a valid country code for BT-40 or BT-55, where BR-CL-14 rejects it.
