If you’re looking to get rid of your old PlayStation Network account, there are a few different ways to go about it. The first option is to delete your account through the PlayStation Network website. This will remove all of your data from the system, including any games or trophies you may have earned. If you want to keep any of your data but want to stop using the account, you can sign out of the PlayStation Network and delete your account from within the system. This will remove all of your data but leave your profile and saved games intact. Finally, if you just want to stop using the account but don’t want to delete it completely, you can disable it on the system. This will prevent other users from signing in and using it, but it will still be accessible if you need to access it in the future. ..

Log into your account on the PlayStation website. Select “PlayStation Network/Account Management” from the drop-down menu. Select “Account Information” and then “Delete Account” to confirm that you want to delete your account.
