Yes, you can change your Roblox username, but it costs Robux and has limits

Roblox lets you change your username through your account settings, but the change is not free. You need Robux — Roblox's in-game currency — to pay for the change. The cost is 1,000 Robux the first time you change your username, and 1,000 Robux each time after that. You can only change your username once every 30 days, so you cannot change it back when ready if you regret the choice.

The username change takes effect right away once you pay. Your old username becomes available for other players to claim after 30 days. Any games, items, or friends you had under your old name stay with your account — the change only affects what other players see when they look at your profile or encounter you in a game.

Key Takeaways

  • Changing your username costs 1,000 Robux and can be done from your account settings under "Change Username".
  • You must wait 30 days between username changes, so plan your new name carefully.
  • Your account, friends list, inventory, and game progress all stay the same when you change your username.
  • Robux can be purchased with real money, earned through game development, or received as a gift from other players.
  • Your old username becomes available for others to use 30 days after you change it.

Where to find the username change option

Log into your Roblox account on the website or mobile app. Click the gear icon in the top right corner to open your settings menu. Select "Account" from the left sidebar. Look for the option labeled "Change Username" — it appears as a button or link in your account details section.

Click on "Change Username" and type in the new name you want. Roblox will tell you right away if the name is already taken or if it breaks the site's naming rules. If the name is available, you will see the price: 1,000 Robux. Confirm the purchase, and the change happens when ready.

How much Robux you need and where to get it

One username change costs 1,000 Robux. If you do not have Robux in your account yet, you can buy it directly from Roblox using real money. A package of 1,000 Robux typically costs around $10 USD, though prices vary by country and payment method. You can also buy larger packages at different price points.

If you do not want to spend money, there are other ways to get Robux. Players who create games on Roblox can earn Robux when other players spend money in their games. Some players also receive Robux as gifts from friends. However, earning Robux through game creation takes time and effort, and gifts depend on someone else choosing to send them to you.

What happens to your old username

When you change your username, your old name does not disappear right away. For 30 days, no one else can claim it — it stays reserved under your account. After 30 days, the old username becomes available for any other player to take. This means if you change your mind and want your old name back, you would have to wait for someone else to stop using it, which may never happen.

Your account history does not change. Games you played, achievements you earned, and items you own all stay attached to your account. Friends who had you added will still see you on their friends list, though your name will now show as your new username. In games, your old chat messages and creations will display under your new name.

The 30-day waiting period between changes

Roblox enforces a 30-day cooldown between username changes. This means once you change your username, you cannot change it again for a full month. The timer starts the moment you complete the purchase. If you change your username on January 15th, you cannot change it again until February 14th.

This rule exists to prevent spam and account abuse. It also gives you time to decide whether you like your new username before paying to change it again. If you are unsure about a new name, think it through before you buy the change.

Usernames that Roblox will not allow

Roblox has rules about what usernames you can choose. You cannot use usernames that contain profanity, slurs, or hateful language. You also cannot impersonate famous people, celebrities, or Roblox staff members. Usernames that are just numbers or that look like they are trying to scam other players (like "Free_Robux" or "Admin_Account") will be rejected.

Usernames must be between 3 and 20 characters long. They can include letters, numbers, and underscores, but not spaces or special characters like hyphens or periods. If you try to create a username that breaks these rules, Roblox will show you an error message and let you try a different name.

What stays the same when you change your username

Your account ID — a number that Roblox uses internally — never changes. This is why all your progress, items, and friends stay with you. Games you created, Robux you own, and any badges or achievements you earned are all tied to your account ID, not your username. The username is just what other players see.

Your email address, password, and two-factor authentication settings do not change. Your account security stays exactly the same. If you had parental controls set up, those remain active. Your game library, purchase history, and any subscriptions like Roblox Premium all continue without interruption.

Frequently Asked Questions

Can I change my username for free?

No. Every username change costs 1,000 Robux, whether it is your first change or your tenth. Roblox does not offer free username changes. The only exception is if you created your account very recently and have not set a username yet — in that case, you can choose your initial username without paying.

What if someone else takes my old username after 30 days?

Once the 30-day period ends, your old username becomes available for anyone to claim. If someone takes it, you cannot get it back unless they change their username and it becomes available again. There is no way to reserve or reclaim a username you no longer use.

Do my friends know when I change my username?

Your friends will see your new username the next time they look at their friends list or encounter you in a game. Roblox does not send a notification to your friends when you change your name. They will just notice that your name is different.

Can I change my username if my account is banned or suspended?

If your account is suspended or banned, you cannot change your username until the suspension or ban is lifted. You also cannot change your username if you do not have enough Robux to pay for it.

What if the username I want is already taken?

Roblox will tell you when ready if a username is already in use. You will need to choose a different name. You can try adding numbers or underscores to a name you like — for example, if "Alex" is taken, you might try "Alex_123" or "Alex1".
