Yes, you can change your Roblox username, but only once every 30 days

Roblox lets you change the name on your account through your account settings. The change takes effect when ready, and your old username becomes available for other players to claim after a short time. However, there is a waiting period: you must wait 30 days after your last username change before you can change it again.

The process itself takes less than five minutes if you already know what name you want. You do not need to contact Roblox support or pay a fee — the feature is built into every account. The main limitation is that your new username must follow Roblox's naming rules, which means no profanity, no impersonation of real people or celebrities, and no usernames that are already taken by another player.

Key Takeaways

  • You can change your username once every 30 days through your account settings on the Roblox website or app.
  • Your new username must be between 3 and 20 characters and cannot contain spaces, special characters, or numbers at the start.
  • Roblox rejects usernames that include profanity, impersonate real people, or are already claimed by another account.
  • Your old username becomes available for others to use after a waiting period, so choose a name you plan to keep.
  • If your username change is rejected, Roblox will tell you why and you can try a different name when ready.

How to change your username on the Roblox website

Start by logging into your Roblox account on the website. Click the gear icon in the top right corner of the page — this opens your account menu. Select Settings from the dropdown list.

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 pencil icon or the Change button next to your username. A text box will appear where you can type your new username.

Type the name you want, then click Verify or Save. Roblox will check whether the name is available and follows the naming rules. If it passes, the change happens right away. If it fails, you will see an error message explaining why — usually because the name is taken, contains banned words, or breaks the character rules.

How to change your username on the Roblox mobile app

Open the Roblox app and log in if you are not already signed in. Tap the three horizontal lines (the menu icon) in the bottom right corner. Scroll down and tap Settings.

Tap Account to open your account settings. Look for the Username section and tap the pencil icon next to your current name. Type your new username in the box that appears, then tap Verify or Save. The app will check the name and confirm the change if it is valid.

Rules for choosing a new Roblox username

Your username must be between 3 and 20 characters long. It can contain letters and numbers, but numbers cannot be the first character — so "Player123" works, but "123Player" does not. Usernames cannot contain spaces, underscores, hyphens, or any special characters.

Roblox automatically rejects names that contain profanity or slurs, even if you try to disguise them with numbers or symbols. The system also blocks usernames that impersonate real celebrities, public figures, or Roblox staff members. If you try a name and it is rejected, the error message will usually tell you which rule it broke, so you can adjust and try again.

Keep in mind that usernames are case-insensitive on Roblox — "PlayerOne" and "playerone" are treated as the same name. If you want a name that is similar to your current one but with different capitalization, that will not work.

What happens to your old username

Once you change your username, your old name does not disappear when ready. Roblox holds it for a period of time — usually several days to a few weeks — before releasing it back into the pool of available names. During that holding period, no one else can claim your old username, and your old name will not appear on your profile.

If you change your mind shortly after a username change, you cannot straightforward change back to your old name right away because of the 30-day waiting period between changes. You would have to wait until the 30 days are up, and even then, your old username might already be taken by someone else if the holding period has ended.

The 30-day waiting period between changes

After you change your username, you must wait 30 days before you can change it again. This timer starts from the moment your change goes through, not from when you requested it. If you change your username on January 15th, you cannot change it again until February 14th.

During this waiting period, you can still use your account normally — play games, chat with friends, and join groups. The restriction only prevents you from changing your username again. If you try to access the username change feature before the 30 days are up, Roblox will show you a message telling you when you will be able to change it next.

What to do if your username change is rejected

If Roblox rejects your chosen username, read the error message carefully — it will tell you whether the name is already taken, contains banned content, or breaks the character rules. If the name is taken, you will need to choose something different. If it contains banned words, try removing or replacing those words.

If you are unsure why a name was rejected, try a completely different username to test whether the problem is with specific words or with the format itself. You can attempt as many different names as you want in a single session — the 30-day waiting period only applies after a successful change, not after rejected attempts.

Frequently Asked Questions

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

Not when ready. You must wait 30 days after your most recent change, and even then, your old username might be taken by another player. If you want to keep a username you like, avoid changing it unless you are certain about the new name.

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

No. Your account stays the same — only the display name changes. Your game progress, inventory, friends list, and Robux balance all remain exactly as they were. Other players will see your new username, but your account history does not change.

What if someone else takes my old username after I change it?

Once the holding period ends, your old username becomes available to anyone. If someone claims it before you decide you want it back, you cannot reclaim it. This is why you should only change your username if you are sure about the new one.

Can I change my username if my account is new?

Yes. There is no minimum account age required to change your username. You can change it as soon as you create your account, as long as your chosen name follows Roblox's rules and is not already taken.

Why does Roblox have a 30-day waiting period?

The waiting period prevents players from rapidly cycling through usernames to evade bans, impersonate others, or cause confusion in the community. It also gives Roblox time to release old usernames back into circulation gradually rather than all at once.
