Historical Note

The address format remains consistent regardless of monarch. During Queen Elizabeth II's reign (1952-2022), it was "Her Majesty The Queen, Buckingham Palace, London SW1A 1AA." The postcode SW1A 1AA is unique to Buckingham Palace.

For other royal family members, use "His/Her Royal Highness [Title], Buckingham Palace, London SW1A 1AA" or their specific household office (e.g., Clarence House for Prince of Wales).
