You can change your Roblox username once every 30 days through your account settings

To change your username on Roblox, log into your account, go to Settings, select the Account tab, and click the "Change Username" button. You'll see your current username and a field to enter a new one. Type the new username you want, check that it's available (Roblox will tell you if it's taken), and confirm the change. The new username takes effect when ready, but you won't be able to change it again for 30 days.

The process is the same whether you're on a computer or mobile device, though the mobile app's Settings menu is sometimes easier to navigate than the website version. If you're under 13, your account may have restrictions that prevent username changes — Roblox applies these limits to accounts flagged as belonging to younger players.

Key Takeaways

  • You can change your username once every 30 days by going to Settings > Account > Change Username on the Roblox website or app.
  • Roblox will tell you when ready if your chosen username is already taken, and you can try a different one without penalty.
  • Your new username takes effect right away, but your old username becomes available for others to claim after a short delay.
  • Accounts flagged as belonging to players under 13 may not be able to change usernames at all, depending on account restrictions.
  • You do not need Robux (Roblox's paid currency) to change your username — the feature is free.

Where to find the username change option

On the Roblox website, click the gear icon in the top right corner of any page while you're logged in. This opens a dropdown menu. Select "Settings" from that menu, then click the "Account" tab on the left side. Scroll down until you see "Change Username" — it's a blue button or link depending on your browser.

On the Roblox mobile app, tap the three horizontal lines (the menu icon) at the bottom right, then tap your username at the top of the menu. This takes you to your profile. Tap the gear icon to open Settings, then look for "Account" and scroll to find "Change Username." The button location can shift slightly between app updates, but it's always in the Account section.

What happens when you enter a new username

When you click "Change Username," a text field appears with your current username highlighted. Delete it and type your new username. As you type, Roblox checks in real time whether that username is available. If someone else has already claimed it, you'll see a message saying the username is taken. If it's available, you'll see a checkmark or confirmation message.

Usernames on Roblox can be 3 to 20 characters long and can include letters, numbers, and underscores. Spaces are not allowed. Roblox filters out usernames that contain profanity or references to real-world violence, so if your chosen name gets rejected, try removing numbers or changing a word.

Once you've entered a username that's available and meets the character rules, click the confirm button (usually labeled "Change" or "Confirm"). The change is when ready — your new username appears on your profile, in games you're playing, and on your friends' lists when ready.

The 30-day waiting period between changes

After you change your username, Roblox locks the username change feature for 30 days. If you try to click "Change Username" before that period ends, you'll see a message telling you when you can change it again. This timer starts from the moment you confirm the change, not from when you first clicked the button.

The 30-day rule applies to every account, with no exceptions. If you change your username and when ready regret it, you cannot change it back right away — you have to wait the full month. This is why it's worth taking a moment to think about your new username before confirming.

What your old username becomes after you change it

When you change your username, your old one doesn't disappear forever. Roblox releases it back into the pool of available usernames after a delay of several days to a few weeks. During that time, no one else can claim it, and if you change your mind within that window, Roblox support cannot restore it for you — you have to wait until the 30 days are up and change back yourself.

Friends and other players who knew your old username will see your new one everywhere once the change takes effect. Their friend lists update automatically. Any messages or posts you made before the change still show your old username, because Roblox doesn't rewrite your history — it only updates your current name going forward.

Restrictions that might prevent you from changing your username

If your account is flagged as belonging to a player under 13, Roblox may disable the username change feature entirely. This is part of Roblox's compliance with child privacy laws. You can check whether your account has this restriction by looking at your Account settings — if "Change Username" doesn't appear, your account likely has age-based restrictions.

If your account has been suspended or banned, you won't be able to change your username until the suspension is lifted. Accounts that have violated Roblox's community standards are sometimes locked from making changes as part of the enforcement action.

Why you might want to change your username

Players change their usernames for many reasons: they've outgrown an old name, they want something that matches a new gaming identity, or they're concerned about privacy and want to distance themselves from an old online presence. Some players change their names to match usernames they use on other platforms, making it easier for friends to find them.

Keep in mind that changing your username doesn't change your user ID — the number Roblox assigns to your account when you create it. Games and friends lists use your user ID behind the scenes, so changing your name won't affect your progress in games or your ability to play with friends. It's purely a cosmetic change to how your name appears.

Frequently Asked Questions

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

Yes, but only after 30 days have passed since your last change. You'll need to wait for the full month, then go back to Settings > Account > Change Username and enter your old name — assuming no one else has claimed it in the meantime. If someone else took it, you cannot get it back.

Do I need Robux to change my username?

No. Changing your username is completely free and does not cost Robux or any real money. Roblox offers this feature to all players at no charge.

Will changing my username affect my games or my progress?

No. Your progress, inventory, and game data are tied to your user ID, not your username. Changing your name won't affect anything you've earned or built in any game.

What if the username I want is taken?

Try a variation: add numbers, use an underscore, or change one word. Roblox will tell you when ready if your choice is available. You can try as many usernames as you want during the change process — you only lock in the 30-day timer once you confirm a change.

Can I change my username if my account is under 13?

It depends on your account settings. Some accounts flagged as belonging to younger players have the username change feature disabled. If you don't see the "Change Username" option in your Account settings, your account has this restriction, and you cannot change your name until the restriction is lifted or your account is updated.
