Minecraft Usernames

This article covers Minecraft usernames for Minecraft: Java Edition. Minecraft on other platforms do not require usernames, but if you play multiplayer on these platforms you will use a Xbox Gamertag.

Are there any requirements in creating a username?


  • Needs to consist of 3-16 characters
  • No spaces

Allowed characters:

  • A-Z (upper and lower case)
  • 0-9
  • The only allowed special character is _ (underscore)

It is no longer possible to create a username with less than three characters.

Where can I find my username?
If you have a Mojang account, your username can be found and changed on your Mojang account page.

Can I change my username?
Users who have a Mojang account (the default account type for all accounts registered after November 2012) can change their username for free at account.mojang.com/me by clicking the (Change) link next to your profile name.

If you sign in with your username, as older accounts do, you'll first need to migrate to a Mojang account before you can change your username.

How often can I change my username?
If you've changed your username already, you'll need to wait 30 days to be able to make another change.

If you change your username, your old name is held for 37 days. This gives you an extra week to change back if you've made a mistake or changed your mind before your previous username becomes available to anyone else.

Is the profile name you want to have unavailable?

If the username you want is unavailable, you will need to choose another name. Mojang support will not be able to help you get a username that is unavailable.  

If I change my username, can someone see my previous usernames?

Yes. Username changes are set up so that you can get a username that you prefer, and are not designed to circumvent bans or anything of that sort. Previous usernames are recorded and visible to anyone.

If my old username had my name in it, can I have this name removed from my username history?Yes. If your current or past usernames have any personally identifiable information in them. You can contact customer support and have it removed from your history. This is strictly limited to personally identifiable information.

After I changed my username, I get error message “not authenticated with Minecraft.net”, what do I do? You’ll need to fully log out and log back in again. This refreshes your profile's authentication and connection with our servers.

To fully log out and log back in:

- In the Minecraft game launcher, click on your username or email address in top right corner

- Click "Log Out"

- Log back in with your account credentials

If I ban someone on my server, and they change their username, do they stay banned?
Yes, and the same is true for whitelisted, or OP'd players. Account-level features on an unmodified server stay the same because the system is using your profile's unique ID instead of the username. This does not include the scoreboard feature, which uses usernames, and is not meant to store lots of long-term player data.

Will Mojang Support help me change my username?
No. The system is set up so that users can change their usernames. If you don't like your username, you can change it again in 30 days. Neither will we help you get a username that is already unavailable nor a name with less than three characters.

What about username moderation? Can I report someone?
Mojang has always had a pretty relaxed stance on usernames. Someone who chooses an inappropriate username is often banned by the servers that they join. Even though username changes are now a feature, people have been able to register questionably appropriate usernames since 2009, and the community has self-regulated. Implementing a comprehensive username filter is quite difficult, and doing so would diminish the openness that has made the game so popular. We would prefer not to have players constantly reporting each other via this help site; instead, please contact your server administrator. That said, we reserve the right to change particularly offensive names to something more cheerful, as needed.
