As we introduce a new name, you might have the desire to do the same. Starting 22 October, 2021 and continuing through 5 November, 2021, all players will be offered a free BattleTag name change. This applies to anyone who does not currently have a free name change available. Existing name changes will not stack for future use.

Players can request a name change through this form. You will receive a notification once your request has been processed. Please allow up to four weeks for processing.

Thanks and we’ll see you in game!

The Overwatch Team
