Yes, you can change your Roblox username, but there are limits and costs

Roblox lets you change your username, but not as often or as freely as you might think. Your first username change is free. After that, each change costs 1,000 Robux — the in-game currency you buy with real money. The price stays the same whether you change it once a year or once a month, but Roblox does not let you change your username more than once every 30 days.

The change takes effect when ready once you confirm it. Your old username becomes available for someone else to claim after 30 days. Friends, game servers, and your profile all update to show your new name right away, but some places in the Roblox ecosystem — like old forum posts or screenshots — will still show your old username because those records do not update automatically.

Key Takeaways

  • Your first username change is free; every change after that costs 1,000 Robux, which you must buy with real money.
  • You can only change your username once every 30 days, even if you have enough Robux to pay for it.
  • The change happens when ready on your profile, friends list, and in active games, but old posts and screenshots keep your old name.
  • You cannot reserve a username before you change to it, so if someone else claims it while you are saving up, you will have to pick something else.

How to change your username step by step

Log into your Roblox account on a computer or phone. Click the gear icon in the top right corner to open Settings. Select "Account" from the left menu. Look for the "Username" section — it will show your current name and a button labeled "Change Username" next to it.

Click that button. Type the new username you want. Roblox will tell you when ready if the name is already taken or if it breaks the content policy — usernames cannot include certain words, and they must be between 3 and 20 characters long. If your choice is available, you will see a green checkmark. If this is your first change, you can proceed for free. If you have changed your username before, the screen will show the cost in Robux and ask you to confirm the purchase. Click the button to complete the change.

What happens to your old username

Your old username does not disappear when ready. For 30 days after you change it, no one else can claim that name — it stays reserved under your account. After 30 days, it becomes available for any other player to take. If you regret your change and want your old name back, you have that 30-day window to change back to it for free, since you are only charged for changes after your first one.

This 30-day hold is important if you have a username you care about. If you change away from it and then change your mind, you can reclaim it without paying, but only if you act within the month. After that, someone else may have already claimed it.

Games and friends will see your new name right away

When you change your username, the update spreads across Roblox almost when ready. Your friends list shows your new name. Games you are playing or have played will display your new username in chat, leaderboards, and game data. Servers do not need to do anything — they pull your current username from Roblox's system every time they need it.

However, anything stored outside the live game system keeps your old name. Old forum posts, comments you left months ago, screenshots other players took, and archived chat logs will still show your old username. Roblox does not go back and rewrite history. If you were known by your old name in a community, some people may not when ready connect your new name to you.

The 30-day waiting period between changes

Even if you have 1,000 Robux saved up, Roblox will not let you change your username again until 30 days have passed since your last change. This limit applies whether you paid for the change or used your free one. The timer starts the moment you confirm the change, not when you click the button to begin.

This rule exists to prevent spam and account takeovers. If someone gains temporary access to your account, they cannot rapidly cycle through usernames to hide their activity. For you, it means you should think through your new username before you confirm, because you are stuck with it for at least a month.

Robux costs and where to buy them

If you have already used your free change, you will need 1,000 Robux to change your username again. Robux is Roblox's premium currency, and you buy it with real money. The cost varies slightly by region, but in the United States, 1,000 Robux costs around $10. You can also earn Robux through Roblox's creator program if you build games or items, but that takes time and is not a quick path to a username change.

You buy Robux directly from Roblox through the website or the mobile app. You can use a credit card, debit card, gift card, or PayPal. Once you buy Robux, it sits in your account until you spend it. There is no expiration date, so you can save up for a username change without rushing.

Why Roblox charges for username changes

Roblox charges for username changes after the first one to reduce spam and impersonation. If usernames were free to change at will, someone could take a name similar to a popular player or creator, cause confusion, and then switch to a different name to avoid consequences. The cost and the 30-day wait make it harder to abuse the system.

The free first change is meant to let you fix a username you chose in a hurry or that no longer fits you. After that, Roblox treats username changes as a premium feature. This also generates revenue for the company, which funds the platform's operation and development.

Frequently Asked Questions

Can I change my username if I have not played in a long time?

Yes. Your ability to change your username does not depend on how recently you have played. As long as your account is active and you have the Robux (or are using your free change), you can change it whenever you want. The 30-day rule between changes is the only timing restriction.

What if the username I want is taken?

You will need to pick a different name. Roblox does not have a waitlist or reservation system for usernames. If someone else has claimed the name you want, it is unavailable. You can check if a name is taken by trying to change to it — the system will tell you when ready whether it is available.

Can I change my username back to my old one for free?

Yes, but only within 30 days of changing away from it. If you change your username and then change your mind, you can switch back to your old name without paying Robux, as long as you do it before the 30-day hold expires. After 30 days, your old username becomes available to others, and if someone has claimed it, you cannot get it back.

Do my Robux or game progress change when I change my username?

No. Your Robux balance, games you own, items in your inventory, and progress in games all stay exactly the same. Only your display name changes. Your account ID — the number behind the scenes — never changes, so the system knows it is still you.

Can I change my username on mobile?

Yes. The process is the same on the Roblox mobile app as it is on the website. Open Settings, go to Account, find Username, and click Change Username. You can pay with the payment method linked to your mobile device.
