Does fortnite support the new gamertag system

Hope you're doing great today Pancake

Looking similar threads, it seems that fortnite uses your Epic account name.

Could you double check this?

Visit your account's ACCOUNT INFO page.
In the box labeled DISPLAY NAME, enter your desired new display name.
Scroll to the bottom of the page and click SAVE CHANGES."

Fortnite was released before the new gamertag policy went into place and does not support that policy. So you'll see the old tag in the game.

I don't see any issues with the new Xbox gamertag format and Fortnite. If you want to change it, you can certainly do so, and it will be updated even when you play Fortnite. Please note that only the first change is free. Subsequent changes will incur a fee.

Here the support page about changing gamertag

Thanks for confirming. During the procedure via https://social.xbox.com/ChangeGamerTag, did you select the option to customize your old gamertag system?

Also, maybe the game you're trying to play supports the new gamertag system. Does it show on your game the new gamertag (new Gamertag system) or your previous old gamertag (old gamertag system)?

Yes, the game should support the new gamertag system. The new system has been out a few years now.
