Some months back, Sony promised the release of one of the most requested features for PSN for many years: The ability to change your PSN ID. After a few months, and some testing with the PS4 Preview Program, Sony has announced today that finally, all users will be able to change their PSN IDs later today, April 10th, 2019.

Along with the announcement, Sony released a small FAQ that answers many questions about how online ID changes will work, notably:

• The first name change will be free, with any preceding name changes costing $9.99, or $4.99 if you're a PS+ subscriber.
• Old IDs are not freed for other users to chose.
• You can revert your new ID to your old one for free, if you don't like your new one.

As noted previously by Sony, there are some caveats with changing your PSN ID: some online games may not function correctly with your new online ID, with no guarantees for any game released before April 1st, 2018. Sony has released a list of games with no issues, and those with some known issues, which can be found here.

The ability to change your username will become available later today, likely around the time Sony updates the PSN Store, and can be done either directly on your PS4 or via any web browser by logging into your PSN profile.

UPDATE: This feature has now been enabled on Sony's end, so users can now change their PSN ID!

I've heard its because you have a unique integer tied to your account but most games still tied your purchases, savedata, and accounts to your plaintext account name. Sony should have prevented this but they didn't and now we're seeing the issues with it.

I’m surprised they didn’t use the API and enforce guidelines to prevent this, even first party titles are affected.

My friend at work already got his first email about name change. Not requested by him. Let's see how much this happens.

I would suggest they change their password immediately.
