You get one free username change, then paid changes only
Roblox lets you change your username once without paying anything. After that first change, each additional username change costs 1,000 Robux — the in-game currency you buy with real money. There is no way around this fee for subsequent changes, and Roblox does not offer exceptions or refunds.
The free change is a one-time benefit tied to your account, not something that resets. Once you use it, you cannot get another free change on that same account, even if you change back to your original name.
Key Takeaways
- Your first username change on Roblox is free, but you only get one free change per account for life.
- After your free change, each new username costs 1,000 Robux, which requires spending real money.
- You can change your username through your account settings on the Roblox website or mobile app.
- Your new username takes effect when ready, but you cannot change it again for three days.
- Usernames must be between three and twenty characters and cannot contain spaces or special characters.
How to use your free username change
Go to the Roblox website and sign into your account. Click your profile icon in the top right corner, then select Settings. On the left side, click Account, and you will see a section labeled Username with your current name displayed.
Click the Change Username button next to your current name. Type your new username into the text box. Roblox will tell you when ready if the name is already taken or breaks the naming rules. If the name is available, click Change Username to confirm. The change happens right away, and you will be logged out and asked to sign back in.
If you are using the mobile app, the process is the same: tap your profile icon, go to Settings, select Account, and tap Change Username. The mobile version works identically to the website.
What happens after you use your free change
Once your free change is used, the Change Username button will show a price: 1,000 Robux. This is the only way to change your username again. You cannot negotiate this price, and Roblox does not offer discounts or alternative methods.
To pay for a username change, you need Robux in your account. You buy Robux through the Roblox website using a credit card, debit card, gift card, or other payment method Roblox accepts in your region. The amount of real money 1,000 Robux costs varies depending on the bundle size you purchase — buying in larger quantities gives you more Robux per dollar, but the smallest purchase option is usually around $5 USD or equivalent in your currency.
After you spend the Robux to change your username, you must wait three days before changing it again. This three-day cooldown applies whether you paid or used your free change.
Rules for your new username
Your username must be between three and twenty characters long. It can contain letters (uppercase and lowercase), numbers, and underscores only — no spaces, hyphens, periods, or other special characters. Roblox will reject any name that violates these rules or that contains words the platform considers inappropriate.
Your username is different from your display name. Your display name is what other players see in games and on your profile, and you can change your display name as often as you want without paying. Your username is your account login and appears in your profile URL — this is what costs Robux to change after your first free change.
If you regret your free change
Roblox does not reverse username changes or restore your free change if you change your mind. Once you use it, it is gone. If you changed to a name you no longer like, your only option is to pay 1,000 Robux for another change.
Before you use your free change, think carefully about the name you want. Test it out by saying it aloud, imagining it on your profile, and checking whether you will still like it in a few months. Many players regret rushing their free change and wish they had planned it better.
Common mistakes to avoid
Do not assume you can change your username back to your original name for free. Once you change away from it, your original username is treated like any other name change — it costs 1,000 Robux. Some players change their username, then want their old name back and are surprised to learn it is not free.
Do not try to change your username more than once every three days. Roblox enforces a three-day waiting period between changes, and you cannot bypass it by paying extra or contacting support. If you try to change before the three days are up, the button will be grayed out and show a countdown timer.
Do not spend your free change on a temporary name you think you will change soon. Treat your free change as a one-time decision. If you are unsure about a name, wait until you are certain before using your free change.
Frequently Asked Questions
Can I change my username back to my original name for free?
No. Once you change away from your original username, it is treated like any other name change. Changing back to it costs 1,000 Robux, just like changing to any other name. Your original username is not protected or special after you change it.
What is the difference between username and display name?
Your username is what you use to log in and appears in your profile URL. Your display name is what other players see in games and on your profile. You can change your display name as often as you want for free, but your username costs Robux after your first free change.
Can I change my username if I have not spent any Robux?
Yes. Your free username change is available to all accounts, regardless of whether you have ever bought Robux. You do not need to spend money to use your one free change.
What if someone else takes the username I want?
If another player takes the name you wanted, you cannot get it unless they change their username later and it becomes available again. Roblox does not reserve usernames or hold them for players. Your only option is to choose a different name.
Do I lose my free change if I do not use it right away?
No. Your free change does not expire. You can use it whenever you want, even years after creating your account. However, once you use it, you cannot get it back.
