Archie and Lilibet’s last name was previously Mountbatten-Windsor.
Even though the change was only recently revealed, it’s apparently been in use since May 2023.
“It represents their unification, and it’s a proud moment.”
Archie and Lilibet’s last names have also been updated on theroyal family’s official website.
This is the second big title change for the Sussex kids in less than a year.
This title change officially occurred when King Charles acceded to the throne in September 2022.
However, as royal parents' titles change, they typically change their kids' last names to match.
Change seems to be a constant with royal last names.
George then declared this new name could be used by all male or unmarried female descendants of the monarch.
Philip himself took the Mountbatten surname in conjunction with his 1947 British citizenship.
Mountbatten-Windsor will likely be used in the future for William’s grandchildren after he accedes the throne.
