You can change your username once every 30 days through your account settings

To change your Roblox username, log into your account on the Roblox website, go to your account settings, find the username field, and enter your new name. The change takes effect when ready. You are allowed one username change every 30 days, and each change costs 1,000 Robux — the in-game currency you can buy with real money or earn through certain activities.

The process is the same whether you play on a computer or mobile device, though you will need to use the website to make the change itself. If you have never changed your username before, your first change still costs 1,000 Robux and follows the same 30-day waiting period as any other change.

Key Takeaways

  • Changing your username costs 1,000 Robux and you can only change it once every 30 days.
  • You must log in through the Roblox website to change your username — you cannot do it from the mobile app.
  • Your new username takes effect right away, but other players may still see your old name briefly in some places due to the game updating its records.
  • Roblox checks new usernames against a filter for inappropriate content, and rejected names will be flagged when ready so you can try again.

Step-by-step: changing your username on the Roblox website

Start by going to www.roblox.com and logging in with your email and password. Once you are logged in, look for the circular icon in the top right corner of the page — this is your profile menu. Click it and select "Settings" from the dropdown menu that appears.

In Settings, look for the "Account" tab on the left side of the page. Click it. You will see a section labeled "Username" with your current name displayed. Click the "Change" button next to it. A text box will open where you can type your new username. Enter the name you want, then click "Change Username" to confirm.

Roblox will check your new name against its content filter. If the name is rejected, you will see an error message explaining why — usually because it contains words the filter blocks. If your name is accepted, the change is complete and your new username is active when ready. You will not be able to change it again for 30 days.

What happens if your new username is rejected

If Roblox rejects your username choice, the system will tell you the name does not meet community standards. This usually means the name contains profanity, references to drugs or alcohol, or other content the filter blocks. You are not charged Robux for a rejected attempt — you can try again with a different name at no cost.

If you are unsure why a name was rejected, try removing numbers, special characters, or any words that might be borderline. Usernames with underscores, numbers, and straightforward words tend to pass the filter more easily. You can try as many times as you want until you find a name that works, and you will only be charged the 1,000 Robux once the name is accepted.

How to get Robux to pay for the username change

The most direct way to get Robux is to buy them with real money through the Roblox website. Go to the Robux page, select the amount you want (packages range from 400 Robux for about $5 to 10,000 Robux for about $100), and complete the purchase through your payment method. The Robux appear in your account when ready.

You can also earn Robux through Roblox games if you are a Roblox Premium member — some games let you trade in-game currency for Robux, though this varies by game. Premium membership costs money as well, so this route is only worth it if you plan to play games that offer Robux rewards. For a one-time username change, buying Robux directly is usually faster.

What to expect after you change your username

Your new username is active when ready in your account settings and on your profile page. However, other players may still see your old username in some places for a few hours or even a day — this happens because Roblox's servers take time to update everywhere the username appears. In games you are already playing, you might see your old name until you rejoin.

Your friends list, chat history, and game progress all stay the same. Changing your username does not affect anything you own, any games you have played, or your account history. People who know your old username can still find you by searching your new one, and you can change it again after 30 days have passed.

Why Roblox charges for username changes

Roblox charges 1,000 Robux per change to prevent spam and protect usernames from being cycled rapidly. Without a cost, players could change their names constantly to evade moderation, impersonate others, or confuse their friends. The fee also discourages people from reserving popular usernames just to keep them from others.

The 30-day waiting period serves the same purpose — it slows down rapid name changes and gives the community time to recognize who you are. Together, the cost and the cooldown make username changes intentional rather than casual.

Frequently Asked Questions

Can I change my username if I just created my account?

Yes. There is no waiting period before your first username change. You can change it as soon as you have 1,000 Robux in your account. After that first change, you must wait 30 days before changing it again.

What if someone else has the username I want?

If the username is taken, Roblox will tell you it is unavailable when you try to change to it. You will need to choose a different name. There is no way to claim or reserve a username that another player is using.

Can I change my username on the mobile app?

No. You must use the Roblox website to change your username. The mobile app does not have this feature. Log in on a computer or mobile browser, go to Settings, and follow the steps from there.

Do I lose anything when I change my username?

No. Your games, items, friends, and account history all stay the same. Only your display name changes. People can still find you by your new username, and you keep everything you owned under your old name.

What if I change my mind right after changing my username?

You have to wait 30 days before you can change it again. There is no way to undo a username change when ready. Plan your new username carefully before you confirm the change.
