Prince Harry and Meghan Markle’s names do not appear on the phone lists for security guards and aides. Rather, code names are used to protect the couple’s privacy.

Peter Dyke, a journalist for Express, the secret identities are used so that if the phone lists of the security staff get lost, the person that will get it will have no idea that the numbers belong to the members of the royal family.

But Dyke also noted that even though the Royals’ names are not listed on the phone list, their secret code names are based on their initials. For instance, DS is used in reference to Prince Harry and Markle who are known as the Duke and Duchess of Sussex.

Prince William and Kate Middleton use DC as their secret code name, which refers to Duke and Duchess of Cambridge.

“If anyone got a hold of a phone belonging to a royal aide or security team member, they won’t find Harry Windsor and Meghan Markle’s names in it. It’s far too risky in the wrong hands. They are given codenames but they are changed regularly for obvious reasons,” the source said.

The same insider detailed one instance at an event when a worker was taken aside by an aide who informed him that he has a call from Prince Harry.

“The assistant held up his mobile for him to see and it had some random name come up on the screen. The chap went ‘Why would I want to speak to him?’ Imagine the surprise he got when he heard Harry’s voice on the other end of the line,” the source said.

In related news, the use of fake names is not new to Princes William and Harry. While studying at the University of St. Andrews, Prince William went by the name of Steve. Prince Harry, on the other hand, used Spike Wells on his secret Facebook account.

Nicknames have also been used among the members of the royal family. For instance, Prince Charles calls Markle Tungsten. Prince William and Middleton call each other babe and darling, respectively.
