Where to Change Your Username in Call of Duty Mobile

You change your Call of Duty Mobile username through your Activision account, not inside the game itself. The game pulls your display name from whatever account you linked when you first played — whether that's an Activision account, Apple ID, Google Play account, or console account. To change what other players see, you log into your Activision account on a web browser, find the profile settings, and edit the name there.

The steps differ slightly depending on which platform you play on, but the destination is always the same: your Activision account settings online. You cannot change your username from inside the Call of Duty Mobile app. Once you change it in your Activision account, the new name appears in the game within a few minutes.

Key Takeaways

  • Your Call of Duty Mobile username comes from your linked Activision account, not from the game app itself.
  • You change your username by logging into your Activision account on a computer or phone browser, not in the game.
  • The change takes effect in Call of Duty Mobile within a few minutes after you save it.
  • If you play on console or mobile, you may need to unlink and relink your account for the new name to sync properly.
  • You can change your username once every 30 days, and the name must follow Activision's content policy.

Steps to Change Your Username on an Activision Account

Go to www.activision.com in a web browser on your phone or computer. Click the sign-in button in the top right corner and log in with the account you use for Call of Duty Mobile. If you are not sure which account that is, open Call of Duty Mobile, go to Settings, and look under Account to see which service is linked.

Once you are signed in, click your account name or profile icon in the top right corner and select Account Settings. On the left side of the page, click Profile. You will see a field labeled Activision ID or Display Name — this is what other players see in the game. Click the pencil icon next to it to edit.

Type your new username into the field. Activision usernames can be 3 to 16 characters long and can include letters, numbers, and underscores. They cannot include spaces or special characters like hyphens or periods. Once you enter the new name, click Save or Confirm. The change takes effect when ready in your Activision account and syncs to Call of Duty Mobile within a few minutes.

What Happens If You Play on Multiple Platforms

If you linked the same Activision account to Call of Duty Mobile, a console, and a PC, changing your username in your Activision account changes it everywhere at once. You do not need to change it separately in each game. The new name appears across all games tied to that account.

If you play Call of Duty Mobile on one device and use a different account on console or PC, you have separate usernames for each. Changing your mobile username does not affect your console or PC name, and vice versa. Each account is independent.

If Your New Username Does Not Appear in the Game

Wait at least five minutes after saving your new username in your Activision account. Call of Duty Mobile sometimes takes a few minutes to sync the change from the Activision servers. Close the game completely and reopen it to force a refresh.

If the old name still appears after 10 minutes, try unlinking and relinking your account. In Call of Duty Mobile, go to Settings > Account and select Unlink next to your account type. Then restart the game and link the account again. This forces the game to pull your current username from Activision's servers.

Username Change Limits and Rules

Activision allows you to change your username once every 30 days. If you changed it recently, you will see a message telling you when you can change it again. Your username must follow Activision's Code of Conduct — it cannot include profanity, slurs, hate speech, or impersonation of real people or celebrities. If your username violates the policy, Activision may reset it to a default name and prevent you from changing it again for a period of time.

If you want to change your username more than once every 30 days, you cannot. You must wait the full 30 days between changes. There is no way to bypass this limit, even if you contact Activision support.

Changing Your Username on Mobile Without a Browser

If you do not want to use a web browser, you can change your Activision username through the Activision app on your phone. read the Activision app from the Apple App Store or Google Play Store, sign in with your account, and navigate to Profile or Account Settings. The steps are the same as on a web browser — find your display name and click the edit button.

The mobile app version of Activision's account settings works the same way as the website. Your new username syncs to Call of Duty Mobile within a few minutes, just as it would if you changed it on a computer.

Frequently Asked Questions

Can I change my username if I just created my account?

Yes. You can change your username when ready after creating your Activision account. The 30-day waiting period only applies between changes — your first change has no waiting period.

What if someone else is using the username I want?

Activision usernames are unique, so if the name is taken, you cannot use it. Try adding a number or underscore to make it different. For example, if "Shadow" is taken, you could use "Shadow_1" or "Shadow42".

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

No. Your rank, weapons, operators, and all progress stay exactly the same. Only your display name changes. Other players will see your new name, but your account data does not change.

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

Yes, but you have to wait 30 days. If you changed your username and want to go back to the old one, you must wait until the 30-day cooldown expires, then change it back. You cannot change it when ready.

What if my username was reset by Activision for violating the Code of Conduct?

Activision will assign you a temporary default username. You can change it to something new, but you may face a cooldown period before you are allowed to change it again. Check your account settings to see if there is a restriction on when you can next change your username.
