The Duke and Duchess of Sussex will no longer use the word royal, as in their "Sussex Royal" branding, a spokeswoman for the couple has said.
Prince Harry and Meghan Markle have announced that they will not be using the branding as of the end of spring this year.
As things stand, the pair use 'Sussex Royal' extensively.
The spokeswoman said: "While the duke and duchess are focused on plans to establish a new non-profit organisation, given the specific UK government rules surrounding use of the word Royal, it has been therefore agreed that their non-profit organisation, when it is announced this spring, will not be named Sussex Royal Foundation.
"The Duke and Duchess of Sussex do not intend to use 'SussexRoyal' in any territory post Spring 2020.
It is believed Harry and Meghan had hoped to continue using the name until the Queen intervened, according The Mirror.
The couple said on Wednesday that their lives as working royals will end on March 31 when they stop representing the Queen and become financially independent.
They will embark on a new chapter in North America, but sources have stressed they "will be in the United Kingdom regularly" and retain the same charitable goals supporting causes from the Commonwealth to mental health.
The duke and duchess will attend the Commonwealth Day service at Westminster Abbey on March 9, likely to be their last official appearance as working members of the monarchy, with the Queen and other senior royals.
The event is normally attended by the Prince of Wales, Duchess of Cornwall and Duke and Duchess of Cambridge and is a major engagement in the Queen's calendar.
