Where to Change Your Username

You change your Call of Duty Mobile username through your Activision account, not inside the game itself. The game pulls your display name from Activision's servers, so any change you make there shows up in Call of Duty Mobile within a few minutes. You cannot change it from the mobile app alone.

The process is the same whether you play on iOS or Android. You will need to log into your Activision account on a web browser — a phone browser works fine — and navigate to your account settings. This takes about five minutes if you know your password, longer if you need to reset it first.

Key Takeaways

  • Your Call of Duty Mobile username comes from your Activision account, so you must change it on Activision's website, not in the game.
  • You need to know your Activision password to change your username, or you will need to reset it first using your email address.
  • The new username appears in Call of Duty Mobile within a few minutes of saving the change.
  • Activision allows you to change your username once every 30 days, so choose carefully if you have changed it recently.
  • Your username must be between 2 and 16 characters and cannot contain certain symbols or offensive words.

Step-by-Step: Changing Your Username on Activision's Website

Open a web browser on any device and go to www.activision.com. In the top right corner, click the sign-in button. Enter the email address or phone number linked to your Activision account, then enter your password. If you do not remember your password, click "Forgot your password?" and follow the reset steps — Activision will send a link to your email.

Once you are signed in, look for your account icon or profile menu in the top right corner and click it. Select Account from the dropdown menu. On the Account page, find the section labeled Basic Info or Profile. You will see a field showing your current username or Activision ID. Click the edit button next to it — usually a pencil icon.

Type your new username into the text field. Activision will tell you when ready if the name is taken or breaks their rules. The username must be 2 to 16 characters long and cannot include spaces, most punctuation, or words Activision has flagged as offensive. Once you see a green checkmark or confirmation that the name is available, click Save or Confirm.

Return to Call of Duty Mobile and restart the app completely — close it and open it again. Your new username should appear within a few minutes. If it does not show up after restarting, wait another five minutes and check again, as Activision's servers sometimes take a moment to sync.

What Happens If Your Desired Username Is Taken

If the username you want is already in use, Activision will not let you save it. You will see an error message saying the name is unavailable. At that point, you have two choices: pick a different name, or wait to see if the other player stops using their account. Activision does not release inactive usernames, so if someone has not played in years, their name stays theirs.

A common workaround is to add numbers or underscores to a name you like. For example, if "Shadow" is taken, you might try "Shadow_1" or "Shadow99". Activision allows underscores and numbers in usernames, so this often works. Avoid spaces — Activision does not allow them.

The 30-Day Waiting Period Between Changes

Activision enforces a rule that you can change your username only once every 30 days. If you changed your username recently, you will see a message on the edit screen telling you when you can change it again. This rule exists to prevent people from constantly switching names to evade bans or confuse other players.

If you are within the 30-day window and need to change your name urgently, you cannot bypass this rule. You must wait until the 30 days have passed. Mark the date on a calendar so you know when you are may be able to access again.

Troubleshooting: Username Not Updating in the Game

If you changed your username on Activision's website but it still shows your old name in Call of Duty Mobile, the most common fix is to fully close and reopen the app. Swipe it away from your recent apps list or force-close it from your phone's settings, then open it fresh. This forces the game to pull your updated profile from Activision's servers.

If the old name persists after restarting, sign out of your Activision account within Call of Duty Mobile and sign back in. Go to the game's settings menu, find the account or login section, and select sign out. Then sign back in with your email and password. This refreshes your connection to Activision's servers and usually resolves sync problems.

In rare cases, Activision's servers take longer than a few minutes to update. If you have waited 30 minutes and the name still has not changed, try restarting your phone entirely. If the problem persists after that, contact Activision Support through their website — they can manually verify that the change went through.

Rules for Choosing a New Username

Activision has specific rules about what usernames are allowed. Your username cannot contain spaces, and it cannot be shorter than 2 characters or longer than 16. Activision blocks usernames that include hate speech, slurs, or sexually explicit words. The system is automated, so sometimes innocent words get flagged — if that happens, try a variation.

You can use letters, numbers, and underscores. Hyphens are sometimes allowed depending on your region. Avoid symbols like @, #, $, or %, as Activision does not permit them. If you try to save a username and get an error, read the error message carefully — it usually tells you what rule you have broken.

Frequently Asked Questions

Will changing my username affect my rank or progress in Call of Duty Mobile?

No. Your rank, level, weapons, and all progress stay exactly the same. Only your display name changes. Other players will see your new name, but your account history and stats remain linked to your Activision ID, which does not change.

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

Yes, as long as your Activision account still exists and you can log in. Inactivity does not prevent you from changing your username. You will still need to wait 30 days between changes if you have changed it before.

What if I want to change my username back to what it was before?

You can change it back, but you still have to wait 30 days from your last change. Activision treats a revert the same as any other username change. If you changed your name yesterday and want your old name back today, you will have to wait 29 more days.

Does my username have to match my Activision account email?

No. Your username and email are separate. Your email is what you use to log in, and your username is what other players see. You can change your username without changing your email, and vice versa.

What if someone else is using a username I used to have?

Activision does not reserve old usernames for previous owners. Once you change away from a name, it becomes available for anyone else to claim. If you want it back and someone else has taken it, you will have to wait for them to change their name or choose something different.
