We allow 1 (one) username change per user.
The Change Username functionality, if enabled for your account, would appear in your Player Profile (Menu > Profile). Tap the 'pencil' icon next to your Avatar shown on your Profile to select a new Username.
If you don't see the Change Username functionality in your Profile and would like to change your username then please contact Player Services to enable the Change Username functionality in your account.
Once you change your username, the Change Username functionality will no longer be available so make sure to select a username that you wish to stick with.
