You get one free username change every 30 days

Roblox lets you change your username once per month at no cost. After you make a change, you must wait 30 days before changing it again. If you try to change it sooner, Roblox will show you the exact date when your next free change becomes available.

The free change applies whether you are changing to a completely new name or reverting to an old one you used before. You do not need to spend Robux (the in-game currency) or real money to use this monthly allowance.

Key Takeaways

  • You can change your username once every 30 days without paying anything.
  • Go to your account settings, find the username field, and type your new name to see if it is available before confirming.
  • Roblox checks your new username against a filter for inappropriate words, and the change takes effect when ready after you confirm.
  • If you want to change your username more than once per month, you must pay 1,000 Robux each time you exceed your free monthly change.
  • Your old username becomes available for other players to claim after you change it, so you cannot reserve it by switching back and forth.

How to change your username through account settings

Open Roblox in your web browser and log in to your account. Click the gear icon in the top right corner of the page to open the settings menu, then select Account Settings from the dropdown.

On the Account Settings page, look for the Username field on the left side. Click in the text box next to your current username and delete it, then type your new username. Roblox will when ready show you whether that name is available or already taken by another player. If it is available, you will see a green checkmark. If it is taken, you will see a red X and a message telling you the name is unavailable.

Once you have typed a name that is available, click the Change Username button. Roblox will process the change when ready, and your new username will appear across your profile, in games, and on your friends' lists right away.

What happens if your username contains filtered words

Roblox runs all new usernames through an automatic filter that checks for profanity, slurs, and other words the platform does not allow. If your chosen name contains a filtered word, Roblox will reject it and tell you the name is unavailable, even if no other player is using it.

The filter sometimes catches words that are not actually offensive — for example, common words that contain letters that spell something inappropriate when read together. If you believe your username was rejected by mistake, you can try slight variations, such as adding a number at the end or using a different spelling. There is no formal appeal process for filtered usernames, so experimenting with alternatives is the fastest way forward.

Checking when your next free change is available

If you have already used your free monthly change, the Account Settings page will show you a message instead of the Change Username button. This message will display the exact date and time when you can make your next free change.

The 30-day timer starts from the moment you confirm your previous change, not from the start of the calendar month. So if you changed your username on March 15, your next free change will be available on April 14.

What happens to your old username after you change it

When you change your username, your old name is released back into the pool of available usernames. Any other player can claim it when ready. Roblox does not hold old usernames in reserve, and you cannot get yours back by switching to a different name and then switching back.

If you are attached to your old username and think you might want it again later, do not change it. Once it is gone, it is gone unless the new owner decides to change their name and releases it again — which is unlikely.

When you have to pay to change your username

If you want to change your username more than once in a 30-day period, each additional change costs 1,000 Robux. You must purchase Robux with real money through the Roblox website or mobile app before you can pay for extra changes.

The paid change follows the same process as the free one: go to Account Settings, type your new username, and click Change Username. Roblox will deduct 1,000 Robux from your account and process the change when ready. The 30-day timer for your next free change resets after any change you make, whether it was free or paid.

Frequently Asked Questions

Can I change my username back to an old one I used before?

Yes, you can change to any available username, including one you used in the past. However, if another player claimed your old username after you changed it, you cannot use it unless they change theirs first. Your old usernames are not reserved for you.

What if I change my username and then regret it when ready?

You cannot undo a username change, but you can change it again once your 30-day waiting period is over. If you want to change it sooner, you must pay 1,000 Robux. There is no refund option for accidental changes.

Does changing my username affect my game progress or items?

No. Your username is just the name other players see. All your game progress, Robux balance, inventory items, and account data stay exactly the same when you change your username.

Why is my username being rejected even though no one else has it?

Roblox filters usernames for inappropriate content automatically. If your name is rejected, it likely contains a word or letter combination the filter flagged. Try adding a number, using a different spelling, or choosing a different name entirely.
