Your Roblox username changes separately from your Xbox gamertag
Changing your Roblox username on Xbox works differently than changing your Xbox gamertag. Your Xbox gamertag is what appears on your console and in Xbox Live — that's handled through Xbox settings. Your Roblox username is what other players see in Roblox games and on the Roblox website, and you change it through Roblox account settings, not through Xbox.
The process is the same whether you're playing Roblox on Xbox, PC, or mobile: you log into your Roblox account online, go to account settings, and change the name there. Your Xbox console doesn't control this part. Once you change it in Roblox, the new name shows up everywhere you play Roblox, including on your Xbox.
Key Takeaways
- Your Roblox username is separate from your Xbox gamertag and is changed through Roblox settings, not Xbox settings.
- You can change your Roblox username once every 30 days, and the change costs 1,000 Robux (Roblox's in-game currency).
- You must be at least 13 years old to change your username, and you need to log into your account on a web browser or the Roblox app to make the change.
- After you change your username, it takes a few minutes to update across all Roblox games and the website.
Steps to change your Roblox username from Xbox
Start by opening a web browser on any device — your phone, computer, or tablet. You don't make this change on the Xbox itself. Go to the Roblox website and log in with the same account you use on your Xbox.
Once you're logged in, look for the gear icon or menu button in the top right corner of the page. Click it and select Settings. On the settings page, find the tab labeled Account. Under Account, you'll see a field with your current username. Click the button next to it that says Change Username.
Type in your new username. Roblox will tell you right away if the name is already taken or if it breaks Roblox's naming rules. If the name is available, you'll see the cost: 1,000 Robux. Click the button to confirm the purchase and change. The new username takes effect within a few minutes, and it will show up the next time you play on your Xbox.
What you need before you start
You need 1,000 Robux in your account to change your username. Robux is Roblox's currency, and you buy it with real money through the Roblox website or the Roblox app. If you don't have enough Robux, you'll need to purchase some before you can complete the name change.
You also need to be at least 13 years old. If your account is under 13, Roblox won't let you change the username, even if you have the Robux. Your age is set when you create the account and can't be changed.
Finally, you can only change your username once every 30 days. If you changed it recently, you'll see a message telling you when you can change it again. This limit applies whether you change it on Xbox, mobile, or web — it's tied to your account, not your device.
Why your new username might not show up right away
After you confirm the change on the Roblox website, it usually takes a few minutes to show up everywhere. If you jump into a Roblox game on your Xbox when ready, you might still see your old name. Close the game completely and reopen it, or wait 5 to 10 minutes and refresh.
If your new name still doesn't appear after 15 minutes, sign out of your Xbox Roblox app completely and sign back in. This forces the app to pull your updated account information from Roblox's servers. After you sign back in, your new username should display in all games.
Username rules and what Roblox won't allow
Roblox has specific rules about what usernames can contain. Your username can be 3 to 20 characters long and can include letters, numbers, and underscores. It cannot have spaces, special characters like hyphens or periods, or words that Roblox flags as inappropriate or offensive.
If you try to use a name that breaks these rules, Roblox will reject it when ready and show you an error message. You'll need to choose a different name. Common reasons for rejection include profanity, impersonation of Roblox staff, or names that look like they're trying to scam other players (like "RobloxSupport" or "RobloxAdmin").
If you don't have enough Robux
You can purchase Robux directly from the Roblox website. Log into your account, click the Robux icon in the top right, and select Buy Robux. Roblox offers different packages — you might buy 400 Robux, 800 Robux, or larger amounts depending on what you need. The cost in real money varies by package and your location.
If you're under 18, you may need a parent or guardian's permission to make a purchase. Some families set up Roblox gift cards instead, which you can redeem for Robux without using a credit card. These are sold at retailers like Target, Walmart, and Best Buy.
Frequently Asked Questions
Can I change my Roblox username without spending Robux?
No. Roblox charges 1,000 Robux for every username change, and there's no way around this fee. This applies to everyone, regardless of how long you've had your account or how many times you've changed it before.
Will changing my Roblox username affect my Xbox gamertag?
No. Your Roblox username and Xbox gamertag are completely separate. Changing one does not change the other. Your Xbox gamertag stays the same unless you change it through Xbox settings.
What happens to my old username after I change it?
Your old username becomes available for other players to use after a short period. Roblox doesn't hold old usernames permanently. If you want to keep a username, don't change away from it.
Can I change my username if I'm under 13?
No. Roblox only allows username changes for accounts that are 13 or older. This is a permanent restriction based on your account's birth date, which you set when you created the account.
How long does it take for my new username to show up in games?
Usually a few minutes. If it hasn't appeared after 15 minutes, close the Roblox app on your Xbox completely and reopen it, or sign out and sign back in. This refreshes your account information.
