"Minecraft" names, also known as usernames, are invented by individual players or generated by websites such as SpinXO.com. Entering any data in the six boxes of the site, then clicking "Spin" generates a list of 30 names suited for a unique "Minecraft" username. Prior to registering a username with Mojang AB, the owner of the game, the NameMC.com website allows users to check the availability of a specific name.
A "Minecraft" username is initially created when registering a PC game copy after purchasing or redeeming a gift code. The mobile version of the game, "Minecraft: Pocket Edition," doesn't require a username. Video game console players use either an XBox gamertag or a Sony PlayStation Network ID, depending on the system used.
Mojang requires players to wait 30 days after initially registering or changing a username before they are allowed to change it again. The old username in a change is held for 37 days until the new username is confirmed, then released for re-use.
Players banned from a multiplayer server for misbehavior in-game cannot evade the ban by changing usernames. The server system tracks banned players based on a unique identification number assigned at initial game registration that can't be altered by players.
