Baby Archie will get an interesting new title when Prince Charles becomes King

This would be cool.

Just days old, and the entire world is talking about Archie Harrison Mountbatten-Windsor. The precious little bub is Meghan Markle and Prince Harry's first child. And lads, he's very very cute from what we've seen. Yesterday, the royal family revealed the baby's full name, and we did notice there was no sign of a title. A great-grandchild of Elizabeth II, Archie is seventh in the line of succession to the British throne, behind his father, Prince Harry. He is also heir apparent to his father's Dukedom of Sussex. His parents decided against his using a title, and he will be known as simply Archie Mountbatten-Windsor, with Master as a prefix when required. Because Prince Harry is the younger son of the Prince of Wales, his son is not automatically a British prince or entitled to be addressed as "Royal Highness", and was initially expected to be styled "like the children of any other duke" before any announcement had been made on this matter. Harry has the option of allowing his son to use one of his subsidiary titles as a courtesy title, such as "Earl of Dumbarton", but has chosen not to do so.

But Archie will - in time - become His Royal Highness Prince Archie when his grandad becomes King Charles (as a grandchild of the Sovereign)

However, there may be a future title for the little royal. According to the 1917 Letter’s Patent decreed by King George V, only grandchildren of the sovereign receive royal titles—not great-grandchildren. Which means if Prince Charles eventually becomes King, he could could become His Royal Highness Prince Archie.
