The steps to change your username on a phone or tablet

Open the Roblox app on your phone or tablet and tap the three horizontal lines (the menu icon) at the bottom right of the screen. Tap your username or profile picture at the top of the menu. On the profile page, look for a settings icon — usually a gear or wrench — and tap it. Scroll down until you see "Change Username" and tap that option.

You will see a text box with your current username. Tap it, clear the text, and type your new username. Roblox will check in real time whether the name is available — if it shows a green checkmark, the name is yours to take. If it shows a red X, that username is already taken and you need to try another one. Once you see the green checkmark, tap the button to confirm the change (usually labeled "Buy" or "Confirm," depending on your device and app version).

The first username change is free. If you change your username again, Roblox charges 1,000 Robux — the in-game currency you buy with real money. The price stays the same for every change after the first one.

Key Takeaways

  • Open the Roblox app, tap the menu icon at the bottom right, then tap your profile picture or username to reach your profile.
  • From your profile, open settings and select "Change Username" to see the text box where you enter your new name.
  • Roblox shows you when ready whether a username is available — a green checkmark means you can claim it.
  • Your first username change is free; any change after that costs 1,000 Robux, which you must purchase with real money.
  • The change takes effect when ready once you confirm it, and your old username becomes available for other players to use.

What happens if your new username is already taken

When you type a username and see a red X next to it, that name is already claimed by another player. You cannot use it. Try a variation instead — add a number, use an underscore, or swap a letter for a similar one. For example, if "SkyWalker" is taken, you might try "SkyWalker123" or "Sky_Walker."

Roblox checks availability as you type, so you will know right away whether your choice works. Keep trying different versions until you find one with a green checkmark. There is no limit to how many names you can test before you settle on one.

Differences between the app and the website

The Roblox app on mobile and the Roblox website both let you change your username, but the steps are slightly different. On the app, you go through your profile menu. On the website, you log in, click your username in the top right corner, select "Settings," and then find "Change Username" in the Account section.

The cost and rules are identical on both — your first change is free, and later changes cost 1,000 Robux. The username availability check works the same way on both too. Use whichever method feels easier to you; the result is the same.

Why Roblox charges for username changes after the first one

The free first change lets you fix a username you chose when you first joined. After that, Roblox charges 1,000 Robux per change to prevent players from switching names constantly, which can confuse friends and make it hard to track player history. The fee is low enough that players who really want a new name can afford it, but high enough that casual name-swapping is not worth the cost.

You do not have to change your username at all if you do not want to. Many players keep the same name for years. The choice is entirely yours.

How to know if your username change went through

After you tap the confirm button, the app will show you a success message or return you to your profile page. Your new username will appear at the top of your profile when ready. If you are in a game when you make the change, you may need to leave and rejoin the game to see your new name appear to other players, but the change is active right away on your account.

If you do not see the change after a few minutes, try closing the app completely and opening it again. This refreshes the app and usually shows your updated username. If the change still does not appear after that, check your internet connection — a weak connection can sometimes prevent the change from saving.

What you cannot do with a username

Usernames on Roblox are permanent in one sense: once you change to a new name, your old name becomes available for someone else to claim within a few minutes. You cannot reserve an old username or get it back later. If you change from "OldName" to "NewName" and then decide you want "OldName" back, someone else may have already taken it.

You also cannot change your username to something that is already in use by another active player, and you cannot use certain words or phrases that Roblox blocks for safety reasons. If you try to use a blocked word, the red X will appear and you will need to choose something else.

Frequently Asked Questions

Does changing my username affect my game progress or items?

No. Your game progress, Robux balance, inventory, and friends list all stay exactly the same. Only your display name changes. Other players will see your new username, but everything you own and have earned remains yours.

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

Only if no one else has claimed it. After you change your username, your old name becomes available to other players within a few minutes. If someone takes it, you cannot get it back. If no one has claimed it yet, you can change back to it, but it will cost 1,000 Robux (since it is not your first change).

What if I see an error message when I try to change my username?

Common errors happen when your internet connection is weak or when Roblox servers are temporarily busy. Close the app, wait a minute, and try again. If the error keeps happening, check that you are connected to WiFi or mobile data and that your connection is stable. If it still does not work, try the change on the Roblox website instead of the app.

How long does the username change take to show up to my friends?

Your new username appears to your friends almost when ready. They will see it the next time they look at your profile or see you in a game. If a friend is already in a game with you when you change your name, they may need to leave and rejoin the game to see the new name appear.
