Roblox gives you one free username change, then charges for the rest
You get one free username change on Roblox. After that, each change costs 1,000 Robux, which is Roblox's paid currency. If you have not used your free change yet, you can do it through your account settings without spending money. If you have already used it, you will need to buy Robux to change your name again.
The free change does not expire — you can use it whenever you want. But once you spend it, future changes are not free. This guide walks you through using your free change and explains what happens after.
Key Takeaways
- Your one free username change lives in your account settings under the "Change Username" option and works when ready after you confirm it.
- After you use your free change, each additional change costs 1,000 Robux, which you must buy with real money or earn through Roblox games that pay out Robux.
- You cannot undo a username change once it is confirmed, so think through your new name before you submit it.
- Your old username becomes available for other players to claim after you change it, usually within a few minutes.
How to use your free username change
Log into your Roblox account on a computer or phone. Go to your account settings by clicking the gear icon in the top right corner of the page (on computer) or tapping the three-line menu (on phone), then select "Settings."
Look for the "Account" tab and scroll down until you see "Change Username." Click or tap it. Type your new username into the box. Roblox will tell you right away if the name is already taken or if it breaks the site's rules. If your new name is available, click "Change Username" to confirm. That is it — the change takes effect when ready, and your free change is now used up.
What you need to know before you change your name
Your new username is permanent until you pay to change it again. Roblox does not let you change your mind for free, so make sure you actually want the new name before you confirm. You cannot reserve a username or change it back to your old one without paying.
Your old username becomes available for other players to use after you change it. If someone else claims it quickly, you cannot get it back. Some players change their name and then when ready create a new account with their old username to keep it, but that means managing two separate accounts.
Your display name is different from your username. Your display name is what other players see in games and on your profile, and you can change it as often as you want for free. Only your actual username (the one you log in with) costs Robux to change after your first free change.
If you have already used your free change
Once your free change is gone, you will need 1,000 Robux to change your username again. You can buy Robux through the Roblox website or app using a credit card, debit card, gift card, or other payment methods Roblox accepts in your country. The cost varies slightly by region, but 1,000 Robux typically costs around $10 USD.
Some Roblox games let you earn Robux if you are a Roblox Premium member, but the amount is small and takes time. This is not a practical way to save up 1,000 Robux just for a username change. If you want to change your name without paying, your only option is to create a new account and start over.
Username rules and what Roblox will reject
Roblox usernames can be 3 to 20 characters long and can include letters, numbers, and underscores. Spaces are not allowed. Usernames cannot contain words that Roblox flags as inappropriate, and the system blocks names that look like they are trying to impersonate Roblox staff or famous players.
If you try to change to a name that breaks these rules, Roblox will show you an error message and will not let you confirm the change. You can try a different name without losing your free change — you only lose it when you successfully complete a change.
Keeping track of your username across games
Your Roblox username is the same across every game on the platform. When you change it, your name changes everywhere at once — in every game you play, on your profile, and in messages. Friends will see your new name when ready, though some games might take a few minutes to update their display.
If you are worried about friends not recognizing you after a name change, you can update your display name to something familiar and change your actual username to something different. Your display name shows up in most places, so friends will still recognize you even if your username is new.
Frequently Asked Questions
Can I get my free username change back if I used it a long time ago?
No. Roblox gives each account one free change, and once you use it, that is it. There is no way to get another free change, even if years have passed. If you want to change your name again, you will need to buy Robux.
What happens to my old username after I change it?
Your old username becomes available for other players to claim. This usually happens within a few minutes. If you want to keep your old username, you would need to create a second account and change that account to your old name before someone else does.
Is there a way to change my username without using my free change?
No. The free change is the only way to change your username without paying. If you have not used it yet, that is your only cost-free option. After that, every change requires 1,000 Robux.
Can I change my display name for free instead of my username?
Yes. Your display name is separate from your username and can be changed as many times as you want for free. Your display name is what most players see in games. Only your actual username (the one you log in with) costs Robux to change after your first free change.
How long does a username change take to go through?
A username change takes effect when ready after you confirm it. You will see your new name right away on your profile and in games, though some games might take a few minutes to update their display of your name.
