The royals, quite literally, go by many names. They accumulate honors and knighthoods on the regular, but it really gets confusing when they travel around the U.K. and seem to assume a new title.

There is also the question of surnames. While the royal family generally doesn't use last names, when required on official documents and the like, the children of the late Queen Elizabeth II can use the last name "Mountbatten-Windsor," a hybrid of the royal House of Windsor and the name their father, Prince Philip, assumed when he became a naturalized British citizen. Others in the royal family, including the Queen's grandchildren and great-grandchildren will sometimes use part of a parent's title; Prince William and Prince Harry used the last name "Wales" from their father's title, the Prince of Wales, while serving in the military, and William's three children do the same since their father inherited the title.

It's made all the more confusing by the fact that most royal family members "have several titles, most of which are rarely used in public life," explains Wendy Bosberry-Scott, a spokesperson for Debrett's, the company behind the comprehensive Peerage & Baronetage. They do, however, each have a relatively simple way to style their respective titles—and that's what's described below. Here, an exhaustive guide to all of the royal family members' titles, and which places they use them.
