The Basic Steps to Change Your Username

To change your Roblox username, you log into your account on the Roblox website, go to your account settings, find the username field, and enter a new name. Roblox charges 1,000 Robux for each username change — that's the in-game currency you buy with real money. The change takes effect when ready once you confirm it, and your old username becomes available for someone else to claim after a short delay.

The process itself takes less than a minute, but you need to own enough Robux before you start. If you don't have 1,000 Robux in your account, you'll need to buy some first through the Roblox website or the Roblox app on mobile.

Key Takeaways

  • Changing your username costs 1,000 Robux, which you must own before you attempt the change.
  • You make the change through your account settings on the Roblox website, not through the game itself.
  • Your new username takes effect right away, but you can only change it once every 30 days.
  • Your old username becomes available for others to use after a few days, so claim your new one carefully.
  • Usernames must be between 3 and 20 characters and cannot contain spaces or most special characters.

Where to Find the Username Change Option

Open a web browser and go to www.roblox.com, then log in with your email and password. Once you're logged in, look for the circular icon in the top right corner of the page — this is your account menu. Click it and select Settings from the dropdown.

In Settings, you'll see a list of options on the left side. Click Account. On the Account page, you'll see a section labeled Username with your current name displayed. Next to it is a button that says Change or Change Username — click that button to open the change form.

What Happens When You Enter a New Username

When you click the Change button, a box appears asking you to type your new username. As you type, Roblox checks whether that name is already taken. If the name is available, you'll see a green checkmark. If it's taken, you'll see a red X and a message saying the username is unavailable.

Roblox also enforces rules about what characters you can use. Your username must be 3 to 20 characters long and can only contain letters, numbers, underscores, and hyphens. No spaces, no periods, no other symbols. If you try to use a character that isn't allowed, the system won't let you proceed.

Once you've entered a name that's available and follows the rules, you'll see the cost displayed: 1,000 Robux. At this point, you haven't spent anything yet — you're just seeing what it will cost. Read the name one more time to make sure it's what you want, because you can't undo the change without paying again.

Confirming the Change and Spending Robux

After you've typed your new username and confirmed it's available, click the button to proceed. The system will ask you to confirm that you want to spend 1,000 Robux. This is your final note to back out without losing money. If you click confirm, the Robux are deducted from your account when ready and your username changes.

The new username is yours right away. You can use it to log in, and other players see it in games and on your profile. Your old username is not deleted — it just becomes inactive and available for someone else to claim after a few days.

The 30-Day Waiting Period Between Changes

After you change your username, you cannot change it again for 30 days. This rule applies whether you paid for the change yourself or someone else changed it for you. If you try to click the Change button during this 30-day window, you'll see a message telling you when you can change it next.

This waiting period exists to prevent people from rapidly switching names to avoid being identified or to confuse other players. It also protects accounts from being changed by someone who gains temporary access to them.

How to Get Robux if You Don't Have Enough

If you don't have 1,000 Robux, you need to buy some. On the Roblox website, click the Robux icon in the top right corner (it looks like a gold coin with an R on it). This takes you to the Robux purchase page, where you can choose how many Robux to buy.

The amount of real money you spend depends on which package you choose. Roblox offers different bundles — for example, 400 Robux, 800 Robux, 1,700 Robux, and larger amounts. To change your username, you need at least 1,000 Robux, so you'd need to buy one of the larger packages. You can pay with a credit card, debit card, gift card, or other payment methods depending on your country.

On mobile, you can also buy Robux through the Roblox app using your phone's payment method (Apple Pay, Google Play, or your carrier billing).

Rules About What Usernames Are Allowed

Roblox has a content policy that applies to usernames. Your username cannot contain words that are offensive, hateful, or sexually explicit. It also cannot impersonate a real person, a celebrity, or a Roblox employee. If your username violates these rules, Roblox may force you to change it without refunding your Robux.

Usernames that look like they're trying to scam people — for example, "RobloxSupport" or "RobloxAdmin" — are also not allowed, because they could trick other players into thinking you work for Roblox. If you're unsure whether a name breaks the rules, it's safer to pick something else rather than risk losing your Robux.

Frequently Asked Questions

Can I change my username on mobile?

You can buy Robux on mobile through the Roblox app, but you need to go to the website on a web browser to actually change your username. The username change option is not available in the mobile app itself.

What if someone else takes my old username?

Once you change your username, your old one becomes available after a few days. If someone claims it before you can, you cannot get it back. You can only change your username again after 30 days have passed, and it will cost another 1,000 Robux.

Do I lose anything when I change my username?

No. Your account, your games, your friends list, your Robux balance, and everything else stays the same. Only the name changes. Other players will see your new username, but your account history and progress remain tied to you.

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

Yes, but only after 30 days have passed and only if no one else has claimed that old username in the meantime. You would need to pay another 1,000 Robux to change it back.

What if I enter a username and it says it's taken, but I've never seen that player?

Roblox has millions of accounts, including many that are inactive or rarely used. A username can be taken even if the account hasn't logged in for years. You cannot see a list of taken usernames — you can only check one at a time by trying to change to it.
