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, but every change after that costs 1,000 Robux — the in-game currency you buy with real money. You can change your username once every 30 days, and the name you pick must follow Roblox's content policy (no slurs, no impersonation, no sexually explicit words).

The change takes effect when ready once you confirm it. Your old username becomes available for someone else to claim after a short period. Any games you've played, items you own, and friends you've made stay with your account — they're tied to your account ID, not your username.

Key Takeaways

  • Your first username change is free; every change after costs 1,000 Robux, which you must purchase with real money.
  • You can only change your username once every 30 days, so plan ahead if you want a specific name.
  • Your account, friends list, inventory, and game progress stay the same when you change your username.
  • Roblox rejects usernames that contain profanity, impersonation, or hateful language, and you'll find out when ready if your choice violates the policy.

Where to change your username in Roblox

Log into your Roblox account on the website or app. Click the gear icon in the top right corner to open Settings. Select "Account" from the left menu, then look for "Username" near the top of the page. Click the "Change" button next to your current username.

Type the new username you want. Roblox will tell you right away if the name is already taken, contains banned words, or breaks the content policy. If it passes, you'll see the cost: free for your first change, or 1,000 Robux for any change after that. Confirm the change, and it's done.

What the 1,000 Robux cost actually means

If you've already used your free username change, you need Robux to change again. One thousand Robux costs money — the exact amount depends on which package you buy, but it typically runs between $10 and $12 USD. Roblox sells Robux in bundles: 400 Robux for about $5, 800 Robux for about $10, and larger packages for more.

You cannot earn 1,000 Robux for free through normal gameplay. Some games let you earn small amounts of Robux, but those are usually limited and require you to be a Roblox developer. For a username change, you're paying out of pocket.

The 30-day waiting period between changes

Once you change your username, you cannot change it again for 30 days. This applies whether your first change was free or you paid for it. If you change your mind when ready after, you're locked in for a month. Plan your new username carefully before you confirm.

The 30-day timer starts the moment you confirm the change, not when you first click the change button. If you're unsure about a name, don't confirm it yet — you can back out of the change screen without losing anything.

What happens to your old username

Your old username doesn't disappear when ready. Roblox holds it for a grace period — usually a few weeks — before it becomes available for someone else to take. During that time, if someone tries to add you by your old name, they'll see that the account no longer uses that username and may be directed to your new one.

Your account ID stays the same forever. Friends, game developers, and anyone who has bookmarked your profile can still find you because Roblox uses your account ID internally, not your username. If someone has you added as a friend, you'll still appear in their friends list under your new username.

Usernames Roblox will reject

Roblox has a content filter that blocks usernames containing profanity, slurs, hateful language, or references to drugs and alcohol. It also blocks names that impersonate famous people or Roblox staff members. The filter is automated, so you'll know when ready if your choice is rejected — you won't have to wait for a human to review it.

Names that are too similar to existing usernames may also be rejected, though Roblox is usually lenient here. Numbers, underscores, and common variations are usually allowed. If your first choice is blocked, try a slight variation or a different name altogether.

If you share your account or have parental controls

If a parent or guardian set up parental controls on your account, they may have restricted username changes. Check your account settings to see if "Account Restrictions" is turned on. If it is, you'll need the parent or guardian to change the setting before you can modify your username.

If you share your account with someone else, changing your username affects everyone who uses that account. Make sure anyone else using it knows you're making the change, since it will be visible when ready to all their friends and in all their games.

Frequently Asked Questions

Can I change my username back to my old one?

Yes, but only after the 30-day waiting period ends and you have the Robux to pay for it (unless it's your first change). Your old username becomes available after a grace period, so you could theoretically claim it again. However, someone else might take it first, so there's no may provide.

Do my friends see my old username or my new one?

Your friends see your new username when ready. In their friends list, your name updates right away. If they're playing a game with you, they'll see your new username in the game as well. Your old username is no longer associated with your account.

What if someone else takes my old username?

Once the grace period ends, your old username is fair game. If someone else claims it, you cannot get it back unless they change their username later and it becomes available again. This is why you should not share your old username with others after you change it.

Can I change my username if I'm under 13?

Yes, the process is the same. However, if your account has parental controls enabled, your parent or guardian may have restricted username changes. Check your settings or ask the account owner to adjust the restrictions.

Does changing my username affect my Robux or game progress?

No. Your Robux balance, inventory, game progress, and all achievements stay exactly the same. The username is just a display name — everything else is tied to your account ID, which never changes.
