Each Minecraft account has a unique identifier called UUID which is used by Minecraft servers to identify a specific user even if the user would change his or her username. Minecraft names or usernames represent Minecraft user profiles that are used when playing Minecraft online on Minecraft servers. You can also check things like UUID, Skin and other information about specific Minecraft profile.
If you're looking for specific Minecraft name or just want to check if Minecraft username is available, you can use our Minecraft name search engine.
