You get one free username change every 30 days

Roblox lets you change your username once every 30 days at no cost. After you change it, you must wait a full month before changing it again. If you change your username and then want to change it back within that 30-day window, you can do so for free — the 30-day timer resets each time you make a change.

The change takes effect when ready. Other players will see your new name right away in games, on your profile, and in chat. Your user ID (a number assigned when you created your account) never changes, so your friends can still find you even if they search for your old name.

Key Takeaways

  • You can change your username once every 30 days without paying anything.
  • The change happens when ready and shows up everywhere — in games, on your profile, and in messages.
  • Your friends can still find you by your old username in some places, because your account ID stays the same.
  • If you change your mind within 30 days, you can change back to your old name for free.
  • Changing your username does not affect your Robux balance, inventory, or game progress.

Steps to change your username on computer

Open Roblox in a web browser and sign into your account. Click the circular icon in the top right corner of the page — this opens a menu with your account options. Select Settings from that menu.

On the Settings page, click the Account tab on the left side. You will see a section labeled Username with your current name displayed. Click the Change button next to it. Type your new username into the text box that appears. Roblox will tell you when ready if the name is already taken or contains words that break the rules. Once you enter a name that works, click Change Username to confirm.

The page will refresh and show your new username. You are done — the change is live across all of Roblox.

Steps to change your username on mobile

Open the Roblox app and tap the three horizontal lines (the menu icon) in the bottom right corner. Tap your username or profile picture at the top of the menu. This opens your profile page. Tap the gear icon in the top right to open Settings.

Scroll down and tap Account Info. You will see your current username with a Change button next to it. Tap Change, type your new username, and tap Change Username to save it. The app will refresh and show your new name.

What happens if your chosen name is taken or blocked

Roblox checks your new username against two things: names already in use and words on its content filter. If the name you want is taken, the system tells you when ready and you must choose a different one. There is no waitlist or way to reserve a name — you have to pick something else.

If your name contains words Roblox flags as inappropriate, you will see an error message. The rules are strict and sometimes catch words that seem harmless. If this happens, remove or change the word and try again. You can include numbers and underscores to make a name work — for example, if "Shadow" is taken, "Shadow_2024" or "Shadow42" might not be.

The 30-day waiting period explained

After you change your username, the next change is locked for 30 days. This timer starts the moment you confirm the change. If you change your mind on day 5, you can change back to your old username for free — but once you do, another 30 days starts. You cannot change again until that second timer runs out.

The timer is per account, not per username. If you change from "Alice" to "Bob" and then back to "Alice" within 30 days, both changes are free. But you cannot change to a third name until 30 days have passed since your most recent change.

Paid username changes and what they cost

If you do not want to wait 30 days, you can pay Robux (Roblox's in-game currency) to change your username when ready. The cost is 1,000 Robux. This does not give you an extra free change — it just lets you bypass the waiting period. After a paid change, you still have to wait 30 days before your next change, whether that change is free or paid.

Robux costs real money. The exact price varies by how many you buy at once, but 1,000 Robux typically costs between $10 and $12 USD. Some players earn Robux by creating games or items, but most have to purchase it.

What does not change when you change your username

Your Robux balance stays the same. Your inventory — all the items, clothing, and accessories you own — stays the same. Your game progress, achievements, and stats do not reset. Friends can still find you because your account ID never changes. Any games you created or items you uploaded remain yours.

The only thing that changes is the name other players see. Internally, Roblox still knows you by your account ID, so nothing breaks when you change your name.

Frequently Asked Questions

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

No. The 30-day waiting period applies whether you change for free or pay 1,000 Robux. Paying only lets you change when ready instead of waiting — it does not let you change again sooner after that.

What if I change my username and then get hacked?

If someone hacks your account and changes your username, contact Roblox Support through the Help page on the website. Explain what happened and provide details about your account. Support can sometimes restore your old username or help you regain control of your account, but response times vary.

Can I see what my old username was after I change it?

Not directly in the app or website. However, other players who knew you by your old name can still search for it and find your profile, because Roblox keeps a record of past usernames tied to your account ID. Your old name will not show on your profile, but it is not deleted from the system.

Do I lose my friends if I change my username?

No. Your friends stay on your friends list because the connection is based on your account ID, not your username. They will see your new name, but the friendship does not break.

Can I change my username if my account is banned or suspended?

If your account is suspended or banned, you cannot change your username until the suspension or ban is lifted. Contact Roblox Support if you believe your account was suspended by mistake.
