Where to change your username

You change your Call of Duty username through your Activision account, not through the game itself. The actual change happens on the Activision website in your account settings, and the new name syncs to all Activision games you play — Call of Duty, Overwatch, Diablo, World of Warcraft, and others.

You will need to log into your Activision account with the email and password you use for Call of Duty. If you have never set up an Activision account separately, your game account is already linked to one, and you can recover the login by using the email address tied to your game profile.

Key Takeaways

  • You change your username on the Activision website, not in the Call of Duty game menu.
  • The change takes effect when ready across all Activision games, but the old name may still appear to other players for a few hours.
  • You can change your username once every 30 days, and Activision reserves the right to reject names that violate their code of conduct.
  • If you play on console, you may have a separate console username that does not change when you update your Activision name.

Step-by-step: changing your name on the Activision website

Go to account.activision.com and log in with your email and password. Once you are logged in, look for "Account" in the top navigation menu and click it. You should see a section labeled "Activision ID" or "Battletag" — this is your Call of Duty username.

Click the edit button (usually a pencil icon) next to your current name. Type your new username into the text field. Activision will tell you when ready if the name is taken or violates their naming policy — profanity, hate speech, impersonation of real people, and sexually explicit terms are all rejected. If your name is rejected, try a different one.

Click "Confirm" or "Save" to lock in the change. The system will ask you to confirm your action, sometimes by entering a code sent to your email. Once confirmed, your new username is active across all Activision games.

What happens to your old username

Your old username becomes available for someone else to claim after a short waiting period, usually 30 days. During that time, the name is reserved under your account and cannot be used by another player. After 30 days, anyone can take it.

Other players may still see your old name in their friends list or in recent match history for a few hours after you change it. This is normal — the change propagates through Activision's servers gradually, and the delay is usually not more than a few hours. If someone messages you using your old name, the message will still reach you.

The 30-day waiting period between changes

Activision enforces a 30-day cooldown between username changes. This means once you change your name, you cannot change it again for 30 days. The timer starts the moment you confirm the change, not when you first try to edit it.

If you made a typo or chose a name you regret, you will have to wait the full 30 days before you can change it again. There is no way to speed this up or request an exception — the restriction is automatic and applies to all accounts.

Console usernames versus Activision usernames

If you play on PlayStation, Xbox, or Nintendo Switch, you have two separate usernames: your console username and your Activision username. Changing your Activision username does not change your console username, and vice versa.

Other players see your Activision username (your Battletag) in Call of Duty lobbies and on the scoreboard. Your console username is what appears on your console's home screen and in your console's friends list, but it does not show up in the game itself. If you want to change how you appear in Call of Duty, change your Activision username. If you want to change your console identity across all games on that platform, change your console username separately through your console's settings.

Names Activision will reject

Activision's naming policy blocks usernames that contain profanity, slurs, hate speech, or sexually explicit content. The system also rejects names that impersonate real public figures, celebrities, or Activision employees. Names that are purely numbers or symbols, or that are too similar to existing Activision usernames, may also be blocked.

If your chosen name is rejected, the website will tell you why — usually with a message like "This name contains prohibited content" or "This name is unavailable." Try removing numbers, changing a letter, or picking a different name altogether. The system checks names against a database, so slight variations of the same word may pass if the original is blocked.

What to do if you cannot log into your Activision account

If you forgot your Activision password, go to account.activision.com and click "Forgot your password?" on the login page. Enter the email address tied to your account, and Activision will send you a password reset link. Check your spam folder if you do not see the email within a few minutes.

If you do not remember the email address you used, or if you cannot access that email anymore, you will need to contact Activision Support. Go to support.activision.com, select "Account & Login" as your issue, and describe your situation. Support can verify your identity and help you regain access, but the process can take several days.

Frequently Asked Questions

Can I change my username back to my old one after 30 days?

Yes. After the 30-day waiting period, your old username becomes available again. You can change your current username to your old one, but you will have to wait another 30 days before changing it again. There is no special process — just follow the same steps on the Activision website.

Will my rank, stats, and cosmetics stay the same after I change my name?

Yes. Changing your username does not affect your rank, battle pass progress, weapon blueprints, operator skins, or any other progress tied to your account. Everything stays exactly as it was — only the name changes.

What if someone else took my old username after 30 days?

Once the 30-day period ends, your old username is fair game for anyone. If someone claimed it, you cannot get it back. You would have to choose a different name or wait to see if that player ever abandons the account, which is unlikely. Plan ahead if you think you might want to reclaim an old name.

Does changing my Activision username change my username in other games like World of Warcraft?

Yes. Your Activision username (Battletag) is shared across all Activision games. If you change it, the new name appears in Call of Duty, Overwatch, Diablo, World of Warcraft, and any other Activision game linked to that account. You cannot have different usernames across different Activision games.

Can I use special characters or spaces in my username?

Activision usernames typically allow letters, numbers, and hyphens, but rules vary slightly. When you try to enter a name with special characters or spaces, the website will tell you when ready if it is not allowed. Stick to letters and numbers if you are unsure — those always work.
