One of the features that has been requested for so long by PlayStation 4 owners has finally been officially confirmed by Sony and it's short notice - PSN Online ID Change feature launches tomorrow, 11 April 2019, so start thinking.
Unless of course you already know the name you'd have taken had you known that people mature with age and that 420noscopemaster won't reflect your character later on.
Anyway, Sony wrote that your online ID can be changed via your PS4 or web browser, so PlayStation 3 and PS Vita users will have to leave their devices to change the ID.
As far as costs go, Sony wrote, "The first change is free, and changes after that will cost £7.99/€9.99. For PlayStation Plus members, it will cost £3.99/€4.99 for each change after the first one."
If you're worried your friends might not tell you apart, make sure you check the option to display your old ID next to the new one for 30 days. You can only choose that option when changing the ID, so take note.
PSN Online users can change their IDs as many times as they'd like, with the only restriction being their own pocketbooks.
Reverting back, however, is free for every ID you've owned, provided that it doesn't violate Sony's Terms of Service.
Moreover, the IDs you've used in the past cannot be taken by others so you could theoretically maintain a group of IDs, reverting to a different one after each name change - effectively doubling the number of name changes.
Not that we'd advise you to do something as pointless as this - we're just pointing out it can be done according to Sony's current rules.
Additionally, Sony warned that while a large majority of PS4 games supports the feature, there is a number of games that might not, hence the free ID reverting feature.
