Where to change your username in the game

Your Call of Duty Mobile username lives in your Activision account, not in the game itself. You change it by logging into your Activision account on a web browser, going to your account settings, and updating the display name there. The change takes effect the next time you launch Call of Duty Mobile.

You do not need to uninstall or reinstall the game. Once you update your Activision account name, the game pulls that new name automatically when you start it up. The process takes about five minutes total.

Key Takeaways

  • Your Call of Duty Mobile username is stored in your Activision account, not in the game app itself.
  • You change it by visiting the Activision website, signing in, and editing your display name in account settings.
  • The new name shows up in Call of Duty Mobile the next time you launch the game.
  • You can change your username once every 30 days, and the name must be between 2 and 16 characters.
  • If you play on console or PC as well, changing your Activision name affects your username across all Call of Duty games.

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

Go to www.activision.com in any web browser and click the sign-in button in the top right corner. Enter the email address and password you use for Call of Duty Mobile. If you have two-factor authentication turned on, you will need to enter a code from your phone or authenticator app.

Once you are signed in, look for your account icon or profile menu, usually in the top right corner. Click it and select "Account" or "Profile Settings". Find the section labeled "Display Name" or "Username". Click the edit button next to your current name, type your new username, and click save or confirm.

The system will tell you if your new name is available. Names must be between 2 and 16 characters and cannot contain certain symbols or offensive words. If your choice is rejected, try a different combination. After you save, you can close the browser and launch Call of Duty Mobile — your new name will appear when you load in.

What happens if you change your name too often

Activision limits username changes to once every 30 days. If you try to change your name again before 30 days have passed since your last change, the system will show you a countdown timer telling you when you can change it again. You cannot bypass this limit.

This rule exists across all Call of Duty games tied to your Activision account. If you changed your name in Call of Duty: Warzone or Call of Duty on console, the 30-day timer applies to Call of Duty Mobile as well.

Changing your name if you play on multiple platforms

Your Activision account is the same whether you play Call of Duty Mobile on your phone, Call of Duty on PlayStation or Xbox, or Call of Duty on PC. When you change your display name in your Activision account settings, it changes everywhere. You cannot have different usernames on different platforms.

This means if you share a console with someone else or play on a friend's account, changing your Activision name will change it for all games tied to that account. Make sure you own the account before you change the name, or talk to the account owner first.

Fixing a name you cannot change back

If you chose a username and now regret it, you have to wait 30 days before you can change it again. There is no way to speed this up or get an exception. Plan your next name carefully, because you will be stuck with it for at least a month.

If your name was reported and removed by Activision for violating their code of conduct, you will be forced to change it the next time you log in. The game will not let you play until you pick a new name. In that case, you can change it when ready without waiting for the 30-day timer.

Names that will not work

Activision blocks usernames that contain hate speech, slurs, or references to real violence. The system also rejects names that are too similar to Activision employee names or famous public figures, though this rule is applied inconsistently. Names with only numbers, only special characters, or excessive repeated letters are usually rejected as well.

If you see an error message saying your name violates the code of conduct, try something completely different rather than just swapping one letter. The filter is automated and sometimes flags names that seem harmless to you but match a pattern the system has learned to block.

If you cannot sign into your Activision account

If you forgot your Activision password, go to www.activision.com, click sign in, and select "Forgot your password?" Enter the email address tied to your account. Activision will send you a password reset link. Click it, create a new password, and you can sign back in.

If you do not remember the email address you used, or if you no longer have access to that email, contact Activision Support through their website. They can help you recover your account, but the process takes longer than a straightforward password reset. Have your phone number and any payment information from your account ready when you contact them.

Frequently Asked Questions

Can I change my username without going to the Activision website?

No. The game app itself does not have a username change option. You must visit the Activision website, sign in to your account, and change it there. The change then syncs to Call of Duty Mobile the next time you open the game.

Will changing my username affect my rank, weapons, or progress?

No. Your username is just a display name. Your rank, unlocked weapons, camos, operators, and all other progress stay exactly the same. Only the name that appears above your character and in the scoreboard changes.

What if someone else is using the username I want?

Usernames in Call of Duty Mobile are not unique across all players — multiple people can have the same display name. If the name you want is rejected, it means it violates Activision's code of conduct, not that someone else has it. Try a different name.

Can I change my username on my phone without a computer?

Yes. You can visit www.activision.com on your phone's web browser, sign in, and change your display name the same way you would on a computer. The process is identical — just smaller on the screen.

How long does it take for my new username to show up in the game?

It usually appears the next time you close and reopen Call of Duty Mobile. If you are already in a match when you change it, finish the match and restart the game to see the new name. The change is when ready on Activision's servers but requires a fresh game launch to display.
