Your Epic Games display name is the name that appears on your account on the Epic Games Launcher, our official forum, AnswerHub, and when you play any of our games on PC/Mac, Switch, or mobile.
If you’ve only played on console (PSN, Xbox, or Switch) and you want to create a display name for your Epic Games account, you will need to upgrade your account to a full Epic Games account. You can find instructions on how to do that here.
Your email address must be verified before you can change your display name. Go here to learn how to verify it, if you haven't done so.
Note: You can change your display name once every two weeks.
