Your Call of Duty username is how other players see you in matches and on leaderboards. Whether you picked something you've outgrown or want a fresh start, you can change it through your Activision account settings. The process differs slightly depending on whether you play on console or PC, but the core steps remain the same across platforms.

These articles walk you through locating the username change option, understanding any restrictions or cooldowns that might explore, and troubleshooting if the change doesn't take effect right away. You'll also learn what happens to your stats and progression when you make the switch, and how to handle situations where your desired name is already taken.
