What you need to know before you change your Minecraft name

You can change the name that appears in-game on a Minecraft Java Edition account once every 30 days through the official Minecraft launcher. The change takes effect when ready in single-player worlds and on servers, though some servers may cache your old name for a few hours. If you play Minecraft Bedrock Edition (the version on Windows 10, Xbox, Nintendo Switch, or mobile), your in-game name is tied to your Microsoft account and cannot be changed separately — you would change your Microsoft account display name instead, which affects all Microsoft services.

The process is straightforward and free. You do not need to buy anything or contact support unless something goes wrong. The main thing to understand is the 30-day waiting period: once you change your name, you cannot change it again for a full month, so choose carefully the first time.

Key Takeaways

  • Java Edition players change their name through the Minecraft launcher by clicking their profile name and selecting "Change Name," and the change takes effect when ready in-game.
  • You can only change your Java Edition name once every 30 days, so you cannot switch back quickly if you change your mind.
  • Bedrock Edition players cannot change their in-game name separately — the name comes from your Microsoft account, which you can change in Microsoft account settings.
  • Servers may show your old name for a few hours after you change it, but this is temporary and does not affect your ability to play.
  • Your UUID (the unique identifier behind your account) never changes, so servers and worlds will still recognize you as the same player.

How to change your name in Minecraft Java Edition

Open the Minecraft launcher on your computer. Log in with your Microsoft account if you are not already logged in. Look for your account name or profile picture in the top right corner of the launcher window and click it.

A dropdown menu will appear. Select "Change Name" from the options. You will see a text field with your current name highlighted. Type your new name — it can be up to 16 characters long and can include letters, numbers, and underscores. Click "Change Name" to confirm. The launcher will tell you whether the name is available. If someone else has already taken it, you will need to choose a different one.

Once the change is confirmed, close and reopen the launcher, then launch the game. Your new name will appear in the main menu and in-game. The change is permanent until you change it again, and you must wait 30 days before making another change.

How to change your name in Minecraft Bedrock Edition

Bedrock Edition does not have a separate name-change feature in the game itself. Instead, your in-game name comes directly from your Microsoft account. To change it, you need to change your Microsoft account display name, which will update your name across all Microsoft services (Outlook, OneDrive, Xbox, and others).

Go to account.microsoft.com in a web browser and sign in with the Microsoft account linked to your Bedrock game. Click "Your info" or "Edit profile" (the exact wording varies). Find the field labeled "Display name" or "Name" and click "Edit." Type your new name and save the change. The next time you launch Minecraft Bedrock, your new name will appear in-game.

Be aware that changing your Microsoft account display name affects everything you do on Microsoft services, not just Minecraft. If you use the same account for work email or other purposes, your new name will show there too.

What happens to your old name and your worlds

When you change your name, your old name becomes available for someone else to take. This usually happens within a few hours. Your UUID — the unique identifier that Minecraft uses to track your account behind the scenes — never changes. This means your single-player worlds, achievements, and server accounts all stay linked to you, even though your visible name is different.

On multiplayer servers, you may see your old name in chat or on signs for a few hours after you change it, depending on how the server caches player data. This is temporary. If you have built structures or placed items, they will still belong to you under your new name once the server updates. Some servers may require you to log out and back in for the change to take effect when ready.

The 30-day waiting period and what it means

Java Edition enforces a 30-day cooldown between name changes. This means if you change your name on January 1st, you cannot change it again until January 31st. The timer starts the moment you confirm the change in the launcher, not when you next log in.

This waiting period exists to prevent account takeovers and name-squatting. If someone gains temporary access to your account, they cannot rapidly cycle through names to hide their activity. For you as a player, it means you should be confident in your choice before you confirm. If you change your name and when ready regret it, you will have to wait the full month before you can change it back.

Troubleshooting: name changes that do not work

If you click "Change Name" and nothing happens, make sure you are logged into the launcher with the correct Microsoft account. Close the launcher completely and reopen it. If the button is greyed out or missing, you may have already changed your name recently — check whether your 30-day cooldown is still active by looking at your profile page on minecraft.net.

If you see an error message saying the name is unavailable, someone else has taken it. Choose a different name. If you see a message about your account not being may be able to access to change names, your account may be too new or may have restrictions. In that case, contact Minecraft support through the official website.

For Bedrock Edition, if your name does not update in-game after you change your Microsoft account display name, sign out of the game completely, close the app, and reopen it. If the change still does not appear, restart your device.

Why you might want to change your name

Players change their Minecraft names for many reasons: they want a name that better matches their current username on other platforms, they have outgrown an old name, or they want to start fresh on a new server. Some players change their name to match a new streaming identity or to distance themselves from old in-game drama.

The name change is purely cosmetic — it does not reset your progress, delete your worlds, or change your account in any way. Everything you have built and earned stays with you. The only real consequence is that your old name becomes available for someone else, and you cannot change your name again for 30 days.

Frequently Asked Questions

Can I change my name more than once every 30 days?

No. Java Edition enforces a strict 30-day cooldown between name changes. If you try to change your name before the cooldown expires, the launcher will tell you when you are may be able to access to change it again. There is no way to bypass this waiting period.

Will changing my name affect my worlds or achievements?

No. Your UUID stays the same, so all your single-player worlds, achievements, and server accounts remain linked to you. Other players will see your new name, but your progress and builds are unaffected.

What if someone takes my old name after I change it?

Your old name becomes available for others to claim, usually within a few hours. If someone takes it, you cannot reclaim it unless they change their name or the account is deleted. This is why you should not share your old name with people you do not trust.

Can I change my name on servers or realms?

No. Your in-game name is controlled by your Minecraft account (Java) or Microsoft account (Bedrock). Servers and realms cannot change your name for you. When you change your account name, it updates everywhere you play.

Is there a cost to change my Minecraft name?

No. Changing your name is free. Minecraft does not charge for name changes, and no third-party service can do it for you.
