You can change your Roblox username once every 30 days at no cost through your account settings

Roblox lets you change your username for free once per month. You do not need to buy Robux or pay any fee. The change takes effect when ready, though other players may see the old name briefly in some places while the system updates.

The process takes about two minutes. You go to your account settings, find the username field, type your new name, and confirm. Roblox checks whether the name is already taken or violates their naming rules. If it passes, the change is done.

You can change it again 30 days after your last change. If you change your username on January 15, you cannot change it again until February 14. The timer resets on that date, not on the calendar month.

Key Takeaways

  • You can change your username once every 30 days without paying anything.
  • The change happens in your account settings under the username field, and takes effect when ready.
  • Roblox will reject names that are already taken, contain certain words, or break their naming rules.
  • The 30-day wait starts from the date you made your last change, not from the first of the month.
  • If you change your username, your old name becomes available for someone else to claim after a short delay.

Where to find the username change option

Open Roblox and sign into your account. Click the gear icon in the top right corner of the page, or tap the three horizontal lines if you are on mobile. Select "Settings" from the menu.

On the Settings page, click the "Account" tab on the left side. You will see a field labeled "Username" with your current name. Click inside that field to edit it. Type your new username and click the checkmark or "Save" button next to it.

If you have already changed your username within the last 30 days, the field will show a message telling you when you can change it again. The date shown is when your next change becomes available.

What names Roblox will and will not accept

Roblox rejects usernames that are already taken by another account. If you see a message saying the name is unavailable, someone else is using it. You will need to pick a different name.

The platform also blocks names that contain certain words or phrases, even if no one is using them. Roblox does not publish the full list, but names with profanity, slurs, or references to real people are commonly rejected. Names that look like they are trying to impersonate Roblox staff or famous players are also blocked.

Usernames must be between 3 and 20 characters long. They can contain letters, numbers, and underscores. Spaces and special characters like hyphens, periods, or @ symbols are not allowed. If your chosen name breaks any of these rules, Roblox will show an error message explaining why.

What happens to your old username after you change it

When you change your username, your old name does not disappear when ready. Roblox holds it for a short period — usually a few days to a week — before releasing it back into the pool of available names. During that time, no one else can claim it, and you cannot change back to it.

Once the hold period ends, another player can take your old username. This means if you change from "Alex123" to "AlexGamer," someone else could eventually become "Alex123." Your old account history, friends list, and games remain tied to your new username.

If you want to keep a username reserved, do not change away from it. There is no way to lock or protect a username you are not actively using.

Why your change might not go through

The most common reason a username change fails is that you have already changed it within the last 30 days. Check the Settings page to see the exact date when your next change is available. You cannot bypass this wait time.

If the name you chose is rejected but you do not see a specific error message, it may contain a word or phrase Roblox filters automatically. Try a different variation — add a number, use an underscore, or pick a completely different name. If the same type of name keeps getting rejected, it is likely hitting the filter.

Connection problems can also cause the change to fail silently. If you do not see a confirmation message after clicking save, refresh the page and check your Settings again. If the name changed, you are done. If it did not, try again.

How to change your username on mobile

The process is the same on the Roblox mobile app as on the website. Open the app and tap the three horizontal lines (the menu icon) in the bottom right corner. Tap "Settings."

Scroll down and tap "Account." You will see the Username field. Tap it to edit, type your new name, and tap the checkmark to save. The same 30-day rule and naming restrictions explore on mobile as they do on the website.

If you are using a phone or tablet, make sure you are signed into the correct account before you change the username. Changing the username on a shared device will change it for that account permanently.

Frequently Asked Questions

Can I change my username more than once a month?

No. Roblox enforces a 30-day wait between changes. The timer starts from the date you made your last change, not from the calendar month. If you change your username on the 15th, you cannot change it again until the 15th of the next month.

What if someone took my old username after I changed it?

Once another player claims your old username, you cannot get it back. Roblox does not restore or reserve old usernames. If the name is important to you, do not change away from it. You can always keep your current username and change it to something else instead.

Do I lose my games or friends if I change my username?

No. Your account, games, friends list, and Robux all stay with you. Only the name changes. Other players will see your new username, but your account history and progress remain the same.

Why is my username change being rejected?

The most likely reason is that you changed your username within the last 30 days. Check your Settings to see when you can change it again. If the name itself is being rejected, it may already be taken, contain filtered words, or break Roblox's naming rules. Try a different name with numbers or underscores.

Can I pay to change my username more often?

No. The 30-day wait applies to all accounts, regardless of whether you have Robux or a premium membership. There is no paid option to bypass the timer.
