Yes, you can change your username in Call of Duty Mobile, but the process depends on which account type you use

Call of Duty Mobile ties your username to your Activision account, not to the game itself. That means changing your name happens in your Activision settings, not in the game's menu. The steps differ slightly depending on whether you play on iOS or Android, and whether you linked your account through Facebook, Google, Apple, or directly to Activision.

The change takes effect when ready across all Call of Duty games you play on that account. You can change your username once every 30 days, and Activision will reject names that contain profanity, impersonation, or hateful language.

Key Takeaways

  • Your Call of Duty Mobile username lives in your Activision account settings, not in the game itself, so you change it there rather than in-game.
  • You can change your username once every 30 days, and the new name appears when ready across all Call of Duty games linked to that account.
  • If you play through Facebook, Google, or Apple sign-in, you must first link a direct Activision account before you can change your username.
  • Activision rejects usernames containing profanity, impersonation, hateful language, or excessive numbers and symbols.

How to change your username on an Activision account

Go to activision.com and sign in with the account you use for Call of Duty Mobile. Click your profile icon in the top right corner and select "Account". Under the "General" tab, you will see your current username next to "Activision ID".

Click the pencil icon next to your username to edit it. Type your new name, then click "Save". Activision will tell you when ready if the name is taken or violates their naming policy. If it is rejected, try a different variation. The new username takes effect right away.

If you signed in through Facebook, Google, or Apple

You cannot change your username through those platforms' settings. Instead, you must create or link a direct Activision account first. Go to activision.com, sign in with your Facebook, Google, or Apple account, and follow the prompts to set up an Activision ID. Once you have done that, follow the steps above to change your username.

If you already have an Activision account but have not linked it to your Facebook, Google, or Apple login, sign in directly at activision.com with your Activision credentials, then go to "Account" and look for "Connected Accounts" to link your social login there.

What happens to your old username

Your old username becomes available for other players to use after you change it. You cannot reclaim it later, so choose carefully if you think you might want to go back. The change is permanent until your next username change, which you can make 30 days after the current one.

Your friends list, match history, and stats all stay attached to your account. The username change does not reset anything — it only changes what other players see when they encounter you in matches.

Usernames Activision will reject

Activision's automated system blocks names that contain profanity, slurs, or hateful language. It also rejects names that impersonate real people, celebrities, or Activision staff. Names with excessive numbers or symbols (like "xXx_Player_xXx") may be flagged, though the exact threshold is not public.

If your name is rejected, the system will usually tell you why. Try removing numbers, using fewer symbols, or choosing a different word entirely. If you believe your name was rejected in error, you can contact Activision Support through their website, though they rarely overturn rejections for names that are straightforward unpopular or unfamiliar.

Changing your username on mobile without a computer

You can change your username entirely from your phone by opening a web browser and going to activision.com. Sign in with your account, navigate to your profile settings, and follow the same steps as above. The mobile version of the website works the same way as the desktop version.

You cannot change your username from within the Call of Duty Mobile app itself — the option does not exist in the game's settings menu. You must use the Activision website, whether on a computer or phone.

The 30-day waiting period between changes

After you change your username, you must wait 30 days before you can change it again. This timer starts the moment you save your new name. Activision enforces this to prevent players from constantly switching names to evade reports or hide their match history.

If you try to change your username before the 30 days are up, the system will show you the exact date when you can make your next change. There is no way to bypass this waiting period, even if you contact support.

Frequently Asked Questions

Will my friends still see me in their friends list after I change my username?

Yes. Your friends list is tied to your account, not your username. After you change your name, your friends will see your new username, but you will still appear in their friends list and they can still invite you to matches.

Can I change my username if I have not played in a long time?

Yes. Your username can be changed whenever you want, as long as you wait 30 days between changes. There is no inactivity rule that locks you out of changing it.

What if someone else took the username I want?

Usernames are unique on Activision accounts, so if someone else has it, you cannot use it. Try adding a number, changing a letter, or choosing a different name. You can also check if the name is available before you commit to changing your current username.

Do I need to change my password when I change my username?

No. Changing your username does not affect your password or security settings. Your login credentials stay the same.

Can I change my username back to what it was before?

Only if 30 days have passed since you changed away from it and no one else has claimed it in the meantime. If someone else took your old username, you cannot reclaim it.
