Hello there[url=https://cdn.discordapp.com/attachments/902560216871239752/989591085506515074/Hellothere.gif],[/url] Unfortunately at this time we are only able to change our Bungie Names once, regardless of if it was intentional, a typo, act of siblings, pets, or other errors… one shot is all we have. Please see https://help.bungie.net/hc/en-us/articles/7648312251284-Bungie-Name-Guide for more information. Bungie has not made any announcements of plans to allow further name changes. Stay tuned to the [url=https://www.bungie.net/en/News]TWaB[/url] and [url=https://twitter.com/BungieHelp]official Twitter[/url] for updates
Since you’ve already changed it, you won’t be allowed to change it again until/unless Bungie offers more changes.
