How to change surname BDO
As an MMORPG in Black Desert Online, you can make your experience more personal by knowing how to change your last name.
This is an MMORPG where you can enjoy large-scale wars and fights or make a solo run for yourself. A specific name can allow other players to better identify you when you switch servers, making it a surname for you.
Changing a surname is not the same as changing a name. Your character name is how other players identify you, and this can change between characters. Your last name works for all your characters and will be used regardless of which one you choose from your account.
