The order Trump signed instructs the Interior Department to update the Geographic Names Information System to reflect the renaming of the Gulf and remove all references to the Gulf of Mexico. It says all federal references to the Gulf of America, including on agency maps, contracts, and other documents and communications shall reflect the renaming.

However, Trump's order only applies to the U.S. government's official position. Though headquartered in the U.S., corporations such as Google and Apple aren't beholden to the president's directive to rename the landmarks, raising questions as to whether they'll update their popular map services to reflect the government's stance.
