The Basic Process: What You Need to Know

You can change your Roblox username through your account settings on the Roblox website or mobile app. The process takes about two minutes, but there are a few rules: you can change your username once every 30 days, and each change costs 1,000 Robux (Roblox's in-game currency). If you have never changed your username before, your first change is free.

The username you choose must be between 3 and 20 characters long, contain only letters, numbers, and underscores, and cannot be already taken by another player. Roblox will reject usernames that violate their community standards, so avoid anything offensive or that impersonates a real person or brand.

Key Takeaways

  • Your first username change is free; every change after that costs 1,000 Robux and can only happen once per 30 days.
  • You change your username in account settings on the Roblox website or mobile app, not in-game.
  • Your new username must be 3 to 20 characters, use only letters, numbers, and underscores, and cannot already belong to another player.
  • Your old username becomes available for other players to claim after you change it, so choose carefully if you want to keep it reserved.

Changing Your Username on the Website

Go to www.roblox.com and sign into your account. Click the gear icon in the top right corner to open your settings menu, then select Account Settings.

In Account Settings, find the Username field on the main page. Click the pencil icon next to your current username to edit it. Type your new username into the box that appears, then click Change Username or Confirm depending on whether this is your first change (free) or a later one (costs Robux).

If you are paying Robux, you will see a confirmation screen showing the cost. Click to confirm, and your username changes when ready. If the name is already taken or violates community rules, Roblox will tell you and ask you to try a different one.

Changing Your Username on Mobile

Open the Roblox app on your phone or tablet and tap the three horizontal lines (menu icon) in the bottom right corner. Tap your profile picture or avatar at the top of the menu to go to your profile page.

Tap the gear icon to open settings, then scroll down and tap Account Settings. Find the Username field and tap the pencil icon next to it. Type your new username and tap Change Username or Confirm. If you are paying Robux, confirm the purchase on the next screen.

The mobile process is the same as the website — your username changes right away once confirmed, and you cannot change it again for 30 days.

What Happens to Your Old Username

When you change your username, your old one becomes available for any other player to claim. This happens when ready, so if you want to keep your old username reserved or think you might want it back later, do not change it. There is no way to hold a username or get it back once someone else takes it.

Friends and other players will see your new username right away. Any games, items, or Robux you own stay with your account — only the name changes. Your profile history and past activity remain tied to your account under the new name.

Troubleshooting Common Problems

If you see a message that your username is unavailable, it means someone else already has it. Try adding a number or underscore to make it unique. If Roblox rejects your username without saying it is taken, the name likely violates their community standards — try something different.

If you do not see the username change option in your settings, you may not have permission to change it yet. New accounts sometimes have a waiting period before the first change is allowed. If you changed your username recently, you must wait 30 days before changing it again — Roblox will show you the exact date you can change it next.

If you changed your username but it did not go through, refresh the page or close and reopen the app. Sometimes the change takes a few seconds to show up. If the problem continues, sign out completely, wait a minute, and sign back in.

Understanding the 30-Day Waiting Period

After you change your username, you cannot change it again for 30 days. This timer starts the moment you confirm the change, not when you first tried to change it. The 30 days is a calendar rule — Roblox counts it as exactly 30 days from the time and date you made the change.

You can still play games, earn Robux, and use all other features during the waiting period. The restriction only applies to changing your username again. If you made a mistake and want to change it back, you have to wait the full 30 days.

Frequently Asked Questions

Can I change my username without spending Robux?

Yes, but only once. Your first username change is always free. Every change after that costs 1,000 Robux. If you have never changed your username, use that free change wisely.

What if someone took my old username right after I changed it?

Unfortunately, there is no way to reclaim it. Once you change your username, the old one is open to everyone. If you think you might want it back, do not change your username in the first place.

Can I change my username if I am under 13?

Yes, the process is the same. However, if your account is under 13, Roblox may have additional restrictions on what usernames are allowed. If your chosen name is rejected, try a different one that does not include personal information or contact details.

Does changing my username affect my games or friends list?

No. Your games, items, Robux, and friends list all stay the same. Your friends will see your new username, but they do not have to re-add you or do anything on their end.

How long does it take for my new username to show up everywhere?

Your new username appears in your account settings and profile when ready. It may take a few minutes to show up in games, chat, and other places across the platform, but usually it is when ready or within seconds.
