Some games may not act as expected after you change your Online ID.
PS4 usernames must be unique, so if you pick a name that somebody’s already chosen, you’ll have to choose again. This screen shows you suggestions of available usernames on the right side of the screen. You can pick any of them by highlighting it and pressing ✕. Sony allows you to pick a new Online ID once for free. If you want to switch your Online ID again, you’ll be charged either $4. 99 (if you’re a PS Plus member) or $9. 99 (if you’re not a member) per change.
You can also click directly on one of the suggested Online IDs that appear below the Change Online ID text field.
