The seller country code (BT-40) must be an ISO 3166-1 alpha-2 code, but "UK" is not in the list. The United Kingdom is "GB" in ISO 3166-1 — "UK" is a reserved code and is not in the list. This code drives place-of-supply, reverse-charge and intra-community logic downstream, so a code the receiver cannot resolve stops the invoice at the door.
BR-CL-14Set seller.address.countryCode to the two-letter ISO 3166-1 code in upper case — "DE" Germany, "AT" Austria, "FR" France, "NL" Netherlands, "GR" Greece, "GB" United Kingdom.
