Hey there. When cross play launched, the new Bungie name system was implemented: [quote]we're converting everyone's name over to an identity that will remain consistent across all platforms you play from. We’re calling this your Bungie Name. While this will cause a one-time naming reshuffle, we feel this is better for everyone in the long run. Here’s how Bungie Names will work and look: "Bungie Name": PlayerName#1234 "Display Name": PlayerName "Hash": # "Numeric ID": 1234 ... If your name ends up empty or includes a moderated term, you will find the quite unremarkable “Guardian[Random Number]” name over your character’s head. While we won’t have a name change feature at launch, we are working diligently to get you an early version of this feature this winter.
