Change your username through your Activision account

Your Call of Duty username in Modern Warfare 3 is tied to your Activision account, not to your console or platform. To change it, you log into your Activision account online, find the username settings, and update it there. The change takes effect the next time you launch Modern Warfare 3.

You can change your username once every 30 days. If you changed it recently, you will see a countdown timer showing when you can change it again. There is no cost to change your username.

The username you choose must be between 3 and 16 characters long, can include letters and numbers, and cannot contain spaces or special characters. Activision reserves the right to reset usernames that violate their code of conduct.

Key Takeaways

  • Go to your Activision account settings online and select the username or profile section to make the change.
  • You can change your username once every 30 days, and the change appears in Modern Warfare 3 after you restart the game.
  • Your new username must be 3 to 16 characters and can only contain letters and numbers.
  • If your desired username is already taken, you will need to choose a different one — the system will tell you when ready.

Step-by-step: updating your username on PC, PlayStation, or Xbox

Start by visiting the Activision account website at activision.com. Click "Log In" in the top right corner and enter the email address and password for your Activision account. If you use two-factor authentication, you will be asked to verify your identity through your phone or email.

Once logged in, look for "Account" or "Profile Settings" in the menu — the exact label depends on whether you are on desktop or mobile. Click it, then find the section labeled "Username" or "Battletag". Click the edit or pencil icon next to your current username.

Type your new username into the field. The system will check in real time whether the name is available. If it shows a green checkmark, the name is yours to claim. If it shows a red X or a message saying the name is taken, choose a different one. Once you see the green checkmark, click "Save" or "Confirm".

Close the browser and launch Modern Warfare 3 on your console or PC. The game may take a moment to sync with your Activision account. Your new username will appear in your profile and in the lobby the next time you play.

What happens if your desired username is already taken

Activision does not hold usernames in reserve, and does not have a waitlist for taken names. If the username you want is already claimed by another player, you cannot use it. The system will show you this when ready when you type it in.

Your options are to choose a variation — adding a number at the end, using an underscore or hyphen if the system allows it, or picking a different name altogether. Some players add their birth year, a favorite number, or initials to make their first choice unique.

Changing your username on console versus PC

The process is the same regardless of whether you play on PlayStation, Xbox, or PC, because the change happens through your Activision account online, not through your console settings. Your console username and your Call of Duty username are separate things. Changing one does not change the other.

If you play on multiple platforms with the same Activision account, the new username will appear on all of them. If you have separate Activision accounts for different platforms, you will need to change the username in each account individually.

Troubleshooting: your username did not change in the game

If you changed your username on the Activision website but it still shows your old name in Modern Warfare 3, restart the game completely. Close it entirely, wait 10 seconds, and launch it again. The game syncs with your Activision account when it starts up, so a full restart usually fixes the delay.

If the old username persists after a restart, sign out of your Activision account within the game and sign back in. On console, go to Settings, select your profile, and choose "Sign Out". On PC, look for the account menu in the top right corner of the launcher and select "Log Out". Then log back in with your credentials.

If you still see the old username after these steps, the change may not have saved on the Activision website. Go back to activision.com, log in again, and verify that your new username appears in your account settings. If it does not, try the change a second time.

How often you can change your username

Activision allows one username change every 30 days. If you changed your username recently, the Activision website will show you exactly when you can change it again. This timer resets 30 days from the date of your last change, not from the calendar month.

If you are locked out of changing your username because you changed it too recently, you have no way to bypass the timer. You will need to wait until the 30 days have passed. There is no appeal process or exception for this limit.

Frequently Asked Questions

Will changing my username affect my rank, weapons, or progress in Modern Warfare 3?

No. Your username is purely cosmetic. 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 lobby changes.

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

Yes, but only if no one else has claimed it in the meantime. If you changed from "OldName" to "NewName" and now want "OldName" back, you can change to it — as long as another player has not taken it during the 30 days you were using "NewName".

What if I forgot my Activision account password?

Go to activision.com and click "Log In". Below the password field, click "Forgot your password?" Enter your email address, and Activision will send you a reset link. Click the link in the email, create a new password, and you can log in and change your username.

Does my console username need to match my Call of Duty username?

No. Your PlayStation Network name, Xbox Gamertag, or Steam username is separate from your Call of Duty username. They can be completely different, and changing one does not affect the other.

Can I use special characters or spaces in my username?

No. Your username can only contain letters (A–Z) and numbers (0–9). Spaces, hyphens, underscores, and other special characters are not allowed. The system will reject your entry if you try to use them.
