How Does This Relate To Prince Harry’s Last Name?Prince Harry’s full name is Prince Henry Charles Albert David, Duke of Sussex. He has no “official last name.” In fact, he’s never used the name Mountbatten-Windsor in his life. His brother, Prince William, similarly, has no official surname, his full name is Prince William Arthur Philip Louis, Duke of Cambridge. Their father, Prince Charles, and their aunts and uncles and most of the cousins are also named simply with their titles.
He Has Used A Surname In The PastWhen Prince Harry joined the military in 2005, his name was “Officer Cadet Wales,” and later Lieutenant Wales. That surname, of course, comes from his father’s title, the Prince of Wales. Like Prince Harry, Prince William also went by Lieutenant Wales during his military service. Neither has ever used Mountbatten-Windsor. For further evidence that Prince Harry doesn’t use that name, consider his son’s birth certificate. On the document, the father is listed as His Royal Highness Henry Charles Albert David, Duke of Sussex. As many have pointed out before, he did not use his “Prince” title. It’s also worth noting that there is in fact no surname. Archie’s mother is listed as Rachel Meghan Her Royal Highness The Duchess Of Sussex. Again, no surname.
