Sony has taken to the PlayStation Blog to reveal that PS4 owners can finally change their PSN ID starting tomorrow, which is an extension of the beta preview program last year.
All PS4 games developed on or after April 1 last year have been developed to support this feature, but there may still be cases where a game isn't fully compatible, which is why Sony advises everyone to consult the list of tested games.
In terms of how you do it, the Q&A on the blog explains that you can visit your PS4, head to settings, account management, account information, profile, and then online ID, at which point you can enter an alternative name. You can change it via a web browser too though, where you can sign into your PSN account and select the edit button next to the online ID. You can't make these changes on PS3 or PS Vita.
In terms of cost, the first change is free, while changes after that cost £7.99 (€9.99, $9.99 USD), reduced to £3.99 (€4.99, $4.99) for PS Plus subscribers. When you do make a change you have the option to display your old ID next to your new one for 30 days to help people find you.
If you want to revert back to your old ID you can do so for free by contacting PlayStation Support, and you'll be pleased to hear that your old ID is only available to you. Child accounts, however, can't change their online IDs at all.
When talking about those few games that might not support the PSN ID change, Sony says that they "expect major issues to occur only in a small number of games," and these issues may include previous online IDs remaining visible to players, losing progress in games, parts of applications not working, and losing access to content.
There's also a rather concerning warning that says: "Please be aware that changing back to a previous online ID may not fix all issues (for example, you may not recover all, or any, lost content, progress, and functionality.)" You can find a list of games with issues identified right here.
Will you change your ID?
