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

To change your username in Roblox, log into your account on the website or app, go to Settings, select the Account tab, and click the button next to your current username. Type your new name, pay the 1,000 Robux fee (the in-game currency), and confirm the change. The new username takes effect when ready, though you can only make this change once per 30-day period.

The 1,000 Robux fee is required every time you change your username — there is no free option. If you do not have enough Robux in your account, you will need to purchase more before you can complete the change. Roblox does not refund the fee if you change your mind within a certain window, so choose carefully before you confirm.

Key Takeaways

  • Username changes cost 1,000 Robux and can only happen once every 30 days, so plan ahead if you want to switch names.
  • You make the change in your account Settings under the Account tab on either the Roblox website or mobile app.
  • Your new username is active when ready, but your old username becomes available for other players to claim after a short delay.
  • Roblox usernames must be between 3 and 20 characters and cannot contain spaces or special characters other than underscores.

Where to find the username change option

On the Roblox website, click the gear icon in the top right corner of the page and select Settings. On the mobile app, tap the three horizontal lines (the menu icon) at the bottom right, then tap Settings. In both cases, look for the Account tab — this is where all your account information lives.

Once you are in the Account tab, you will see your current username displayed near the top. Next to it is a button or link that says "Change" or shows an edit icon. Click or tap this to open the username change window. If you do not see this option, make sure you are logged in and that your account is in good standing (no active bans or restrictions).

What usernames Roblox will and will not allow

Your new username must be between 3 and 20 characters long. You can use letters (uppercase and lowercase), numbers, and underscores, but not spaces or special characters like hyphens, periods, or symbols. Roblox also blocks usernames that contain profanity, impersonate real people or brands, or violate their community standards.

If you try to claim a username that is already taken, Roblox will tell you when ready and ask you to choose a different one. The system checks availability in real time, so you will know right away whether your choice is open. If you are set on a particular name and it is taken, you can check back later — inactive accounts eventually release their usernames, though Roblox does not publish a timeline for when this happens.

How to get Robux if you do not have enough

If your account does not have 1,000 Robux, you will need to purchase some before you can change your username. You can buy Robux directly through the Roblox website or app using a credit card, debit card, gift card, or PayPal. Roblox also offers a subscription called Roblox Premium that gives you a monthly allowance of Robux — the lowest tier is about $5 per month and includes 450 Robux.

Be aware that Roblox frequently runs sales and promotions on Robux bundles, so if you are buying specifically to change your username, it may be worth waiting a few days to see if a discount appears. You can also earn Robux through the Roblox Developer Exchange program if you create games or items, but this requires significant time and effort and is not a practical route for a quick username change.

What happens to your old username after you change it

Your old username does not disappear from Roblox history. Other players will still see it in chat logs, on items you created, and in their friend lists for a short time. However, the username itself becomes available for someone else to claim after a brief holding period — usually a few days to a week, though Roblox does not specify the exact timeline.

If you are concerned about your old username being taken by someone else, you do not need to worry about impersonation in the traditional sense. Roblox usernames are not unique identifiers in the way email addresses are — the system uses a behind-the-scenes user ID to track your account, so changing your name does not affect your friends list, your game progress, or your inventory. Your old username is straightforward released back into the pool.

Why you might want to change your username

Players change their usernames for many reasons: they created an account as a child and want something more mature, they want a name that matches a username on another platform, or they straightforward want a fresh start. There is no penalty for changing your name, and it does not affect your account security or your game progress in any way.

Keep in mind that if you are known in a game community by your current username, changing it might confuse other players who know you. Some players leave their names alone for this reason, while others see it as a chance to rebrand. The choice is entirely yours, and you can change it again in 30 days if you change your mind about the new name.

Troubleshooting common problems with username changes

If the Change button is not appearing in your Account settings, check that you are logged in and that your account is not restricted. Roblox sometimes temporarily locks accounts that have violated community rules, and you will not be able to change your username until the restriction is lifted. If you think your account is restricted unfairly, you can contact Roblox Support through their help center.

If you see an error message when you try to confirm your new username, it usually means either the name is already taken, it contains forbidden characters, or your Robux payment did not go through. Try a different username, double-check that you have enough Robux, and make sure your payment method is valid. If the problem persists, clear your browser cache and try again, or switch to the mobile app if you were using the website.

Frequently Asked Questions

Can I change my username back to my old one?

Yes, but you will have to wait 30 days after your first change, and you will pay another 1,000 Robux. Your old username must also still be available — if someone else claimed it in the meantime, you cannot reclaim it. Plan your username changes carefully to avoid this situation.

What if someone else takes my old username?

There is no way to reserve or protect an old username. Once it is released, it is first-come, first-served. If you are worried about this, you can create a second account and claim your old name on it, though this requires another Roblox account and is not necessary for security reasons.

Do I lose my games, items, or friends if I change my username?

No. Your account ID stays the same, so all your progress, inventory, and friend list remain exactly as they were. Only the display name changes. Your friends will see your new username in their friend list, but they will not be unfriended.

Can I change my username more than once every 30 days?

No. Roblox enforces a 30-day cooldown between username changes. If you try to change it again before 30 days have passed, the system will tell you when you are may be able to access to change it next.

Is there a way to change my username without paying Robux?

No. The 1,000 Robux fee is mandatory for every username change. Roblox does not offer free username changes under any circumstances, though new accounts get a free username choice when you first create them.
