You can change your Roblox username once every 30 days without paying

Roblox lets you change your username for free once per month. You do this through your account settings on the Roblox website or mobile app — no payment required, and no special permission needed. The change takes effect when ready, though some games may take a few minutes to show your new name.

If you have changed your username within the last 30 days, you will have to wait until that 30-day window closes before you can change it again. Roblox counts from the date of your last change, not from the calendar month. If you changed your name on March 15, you can change it again on April 15.

Key Takeaways

  • You can change your username once every 30 days at no cost through your account settings.
  • The change happens when ready in most places, though some games may take a few minutes to catch up.
  • If you have already changed your name this month, you will see a countdown timer showing when you can change it again.
  • Changing your username does not affect your Robux balance, game progress, or friends list.
  • If you want to change your name more than once per month, you would need to pay Robux, but the free monthly change is always available.

Steps to change your username on desktop

Go to the Roblox website and sign into your account. Click the gear icon in the top right corner of the page, then select "Settings" from the menu that appears.

In the Settings page, look for the "Account" tab on the left side. Click it, then find the field that shows your current username. Click the "Change Username" button next to it. Type your new username into the box that appears and click the checkmark button to confirm.

Roblox will tell you right away if the name is already taken or if it breaks the site's naming rules. If your new name is available, the change is done. You will be signed out and asked to sign back in with your new username.

Steps to change your username on mobile

Open the Roblox app and tap the three horizontal lines (menu icon) in the bottom right corner. Scroll down and tap "Settings."

Tap "Account" at the top of the Settings screen. Find your username and tap "Change Username." Type your new name and tap the checkmark to confirm. The app will check whether the name is available and let you know if there is a problem.

Once the change is confirmed, you will be signed out. Sign back in with your new username to finish.

What happens to your account when you change your username

Your Robux balance, game progress, friends list, and inventory all stay exactly the same. Your account ID — the number Roblox uses to track you behind the scenes — never changes. Games you have played, items you own, and people who follow you will all still be connected to your account.

People who were your friends before the change will still see you as a friend after. If someone bookmarked your profile or sent you a message, they can still find you by your new username. The only thing that changes is the name itself.

What to do if you cannot change your username yet

If you see a message saying you cannot change your username, it means you have already changed it within the last 30 days. The Settings page will show you a countdown timer with the exact date and time when you can change it again.

There is no way to speed up this timer. You have to wait the full 30 days. If you want to change your username more than once per month, Roblox does offer paid username changes using Robux, but the free monthly change is always your first option.

Rules for choosing a new username

Your new username must be between 3 and 20 characters long. You can use letters, numbers, and underscores. Roblox will not let you use spaces, special characters like hyphens or periods, or words that violate the site's community standards.

If you try a name and Roblox rejects it, the site will tell you why — usually because it is already taken, too short, too long, or contains a word that is not allowed. You can try as many names as you want during the change process. You only use up your one free monthly change once you confirm a name that Roblox accepts.

Frequently Asked Questions

What if someone else took the username I want?

Usernames on Roblox are first-come, first-served. If the name you want is already taken, you cannot use it. Try a variation — add a number, an underscore, or a short word to make it unique. You can try different names as many times as you want before you confirm one.

Can I change my username back to what it was before?

Yes, if no one else has taken your old username. You can change back to any previous name as long as it is still available. This still counts as your one free change per month, so you will have to wait 30 days before changing again.

Do my friends see my old username or my new one?

Your friends see your new username when ready. In their friends list, in games, and in messages, you will appear with your new name. Old messages you sent them will still show your old name, since those are part of the message history.

Will changing my username affect my game progress or items?

No. Your progress, items, Robux, and everything else tied to your account stays the same. The username is just the name people see — it does not affect anything you own or have done in games.

What if I see an error message when I try to change my username?

Common errors mean the name is taken, too short or too long, or contains words Roblox does not allow. Try a different name. If you see a different kind of error, sign out and sign back in, then try again. If the problem continues, check the Roblox status page to see if there are any site-wide issues.
