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 have to wait a full month before you can change it again. If you want to change it more often than that, you'll have to pay Robux — Roblox's in-game currency — each time.

The free change resets on the same day each month. If you change your username on March 15, your next free change becomes available on April 15. This applies whether you use the free change or pay for a change — either one starts the 30-day timer.

Key Takeaways

  • You can change your username once every 30 days without paying anything.
  • Paid username changes cost 1,000 Robux if you want to change it before the 30 days are up.
  • You change your username through your account settings on the Roblox website, not in the game itself.
  • Your old username becomes available for other players to claim after you change it.
  • Changing your username does not affect your account, your games, your friends, or your Robux balance.

How to use your free username change

Go to the Roblox website and sign into your account. Click the gear icon in the top right corner and select Settings. On the left side, click Account. You'll see a section labeled Username with a button that says Change or Change Username.

Click that button. Type in the new username you want. Roblox will tell you right away if the name is already taken or if it breaks their naming rules — usernames can't have spaces, can't be only numbers, and can't contain certain words. Once you pick a name that works, confirm the change. It takes effect when ready.

If the button says Change for 1,000 Robux instead of just Change, your 30 days haven't passed yet. You can still change your name, but you'll have to spend Robux to do it.

What happens to your old username

Once you change your username, nobody can see it on your profile anymore. Your old name goes back into the pool of available usernames. Other players can claim it if they want to — there's no holding period. If you had a popular username and you're worried someone else will take it, you might want to have a new name ready before you make the change.

Your account itself doesn't change. Your friends can still find you, your games are still there, and your Robux balance stays the same. The only thing that changes is the name that appears next to your avatar.

When you might want to pay for an extra change

If you need to change your username before 30 days have passed, you can pay 1,000 Robux to do it when ready. This costs real money if you don't already have Robux in your account — 1,000 Robux typically costs around $12.50 USD, though prices vary by region and by how many Robux you buy at once.

Most players use the free change and wait the month if they need to change again. Paying for extra changes makes sense only if you need a different name urgently — for example, if your current name is causing problems with other players or if you're setting up a new gaming identity for streaming or content creation.

Usernames you can't use

Roblox blocks certain usernames automatically. You can't use names that are already taken, names that are only numbers, or names with spaces. The system also blocks names that contain profanity, slurs, or references to real-world violence or illegal activity.

If you try a name and Roblox rejects it, the message will usually tell you why — either it's taken, it has a space, or it violates the naming policy. Try a different variation. Adding numbers to the end of a name, using underscores instead of spaces, or shortening the name usually works.

Changing your username on mobile

You can't change your username through the Roblox mobile app. You have to use a web browser on your phone or computer. Open roblox.com in Safari, Chrome, or whatever browser you use, sign in, and follow the same steps as above — Settings, Account, Username, Change.

This is a limitation of the app, not your account. Your account works the same way whether you access it from a phone or a computer.

Frequently Asked Questions

Can I get my old username back if I change my mind?

Not directly. Once you change your username, the old one goes back into circulation. If someone else claims it, you can't reclaim it. If nobody has taken it yet, you could change your username back to it within the 30-day window, but you'd have to pay 1,000 Robux to do so before your free change resets.

Does changing my username affect my friends list or my games?

No. Your friends can still see you in their friends list, and all your games, items, and progress stay attached to your account. The only thing that changes is the name displayed next to your avatar.

What if my username is reported or banned?

If Roblox removes your username for violating their naming policy, you'll be forced to change it. You won't get a free change in this case — you'll have to pick a new name when ready. After that, your 30-day timer starts fresh.

Can I reserve a username before I change to it?

No. Usernames aren't reserved. You pick your new name when you make the change, and it takes effect right away. If you want a specific name, make sure it's available before you start the change process.

Do I lose Robux or items when I change my username?

No. Your Robux, your inventory, your game progress, and everything else tied to your account stays exactly the same. Only the display name changes.
