What if my Gamertag or PlayStation Network Online ID is linked to the wrong account?
If you’ve previously linked your Gamertag or PlayStation Network Online ID across multiple accounts, or if they’re linked to an account you don’t use, contact us for advice about the best way to bring all of your games together.
Options include:
- If you’ve got multiple EA Accounts with games on them, but your console ID is only linked to one account, we may be able to move your other games to that account.
- If you have multiple EA Accounts with games and console IDs attached to them, we’ll discuss options for moving those accounts with you. We can only move them to an account that does not already have a PlayStation Network Online ID or Gamertag attached to it.
If we move an account with a PlayStation™Network Online ID or Xbox Gamertag on it, this will mean losing your game progress, in-game items you purchased or earned, saved games, trophies, and achievements.
This includes Origin cloud saves, multiplayer, online progression, and sometimes offline saves.
You may also lose access to some game content and online services for some games.
Your EA Advisor will discuss all of this with you and help you find the best option for your accounts.
