You can change your Xbox username directly in the Xbox app on your phone in about five minutes

Open the Xbox app, tap your profile icon in the top left corner, then select "Customize profile." Tap "Gamertag" and enter your new username. Xbox will check whether it's available in real time. If it is, confirm the change and you're done — the new name appears across all your Xbox devices within seconds.

The process is the same whether you're on iPhone or Android. You don't need a computer, you don't need to call support, and you don't need to own an Xbox console. If you have an Xbox account, you can change the name from your phone.

Key Takeaways

  • Open the Xbox app, tap your profile icon, select "Customize profile," then tap "Gamertag" to change your username.
  • Xbox checks availability when ready as you type, so you'll know right away whether your chosen name is taken.
  • The change takes effect across all your Xbox devices — console, PC, and mobile — within seconds.
  • You can change your gamertag once every 30 days at no cost; additional changes within that window cost money.
  • Your old username becomes available for someone else to claim after you change it.

Step-by-step: changing your gamertag in the app

Start by opening the Xbox app and signing in if you're not already. Tap the profile icon — it's a small circle or square in the top left corner of the home screen. This opens your profile menu.

From the menu, tap "Customize profile." You'll see several options, including "Gamertag," "Bio," and "Avatar." Tap "Gamertag." A text field will appear with your current username highlighted. Delete it and type your new one.

As you type, Xbox checks the name against its database. You'll see a checkmark if the name is available or a message if it's taken. Once you see the checkmark, tap "Save" or "Confirm" (the exact button label varies slightly by phone type). The change is now live.

What happens to your old username

When you change your gamertag, your old one is released back into the pool of available names. Anyone else can claim it after you change yours. This happens when ready, so if you're worried someone might take a name you used to have, there's no way to reserve it or get it back later.

Your account history, achievements, and friends list all stay with your new gamertag. Nothing is lost — only the name changes. People who had you on their friends list will see your new name the next time they open the app.

The 30-day rule and what it costs

Xbox lets you change your gamertag once every 30 days at no cost. If you want to change it again before 30 days have passed, you'll be charged money — the exact amount varies by region but is typically between $5 and $10 USD.

The 30-day timer starts from the moment you confirm your change, not from when you first opened the app. If you change your name on a Monday, you can change it again for free the following Monday. If you try to change it on Sunday, you'll see a message telling you how many days remain and what the cost would be.

Choosing a name that won't get rejected

Xbox has rules about what characters and words are allowed in a gamertag. You can use letters, numbers, and spaces. You cannot use special characters like hyphens, underscores, or periods. Profanity and slurs are blocked, as are names that impersonate real people or celebrities.

Names must be between 3 and 15 characters long. If you try a name that breaks these rules, Xbox will tell you specifically what's wrong — for example, "contains a special character" or "too short." You can then adjust and try again.

The app checks these rules in real time, so you'll know when ready whether your choice will work. There's no penalty for trying a name that doesn't work; you just type a different one and try again.

If the app won't let you change your name

The most common reason the change button is greyed out or missing is that you're within the 30-day window and haven't paid the fee. Check the message on the "Gamertag" screen — it will tell you exactly how many days you have to wait or what the cost is.

If you see an error message instead, try signing out of the app completely, closing it, and signing back in. Sometimes the app needs to refresh your account status. If that doesn't work, try the change on a different device — a computer or console — to see whether the problem is specific to your phone or your account.

If you're still stuck, you can contact Xbox Support through the app itself. Tap your profile icon, scroll down to "Help," and select "Contact us." Support can tell you whether there's a hold on your account or another reason the change isn't going through.

Frequently Asked Questions

Can I change my gamertag back to my old one?

Yes, but only if no one else has claimed it. If someone took your old name after you changed it, you cannot get it back. You would have to choose a different name. If your old name is still available, you can change to it the same way you changed to your new one, subject to the 30-day rule.

Will my friends see my old name or my new name?

They'll see your new name. The change is when ready across all devices and all friends' lists. If they're in a game with you when you change it, they may see the old name until they restart the app or the game, but it updates within minutes.

Do I need an Xbox console to change my gamertag?

No. You only need an Xbox account and the Xbox app on your phone. The change works the same way whether you own a console or not, and it syncs to any console, PC, or device linked to your account.

What if I change my mind right after changing my gamertag?

You can change it back when ready, but it will count as your second change within 30 days, so you'll be charged the fee. If you change your mind, you're better off waiting until the 30-day window closes to change it again for free.

Can I use spaces in my gamertag?

Yes, spaces are allowed. You can have spaces between words — for example, "Cool Gamer" is valid. However, you cannot start or end your gamertag with a space, and Xbox will not let you use multiple spaces in a row.
