Offline UUID converter

Offline UUID converter

Offline mode servers do not ask Mojang who you are, so they generate a UUID from your name instead. This is that UUID.

Minecraft username

Up to 16 characters, letters, numbers and underscores.

When you need this

Whitelists, operator files, permission plugins and ban lists all key on UUIDs. On an offline mode server those UUIDs are derived from the username, so you can work one out without the player ever joining.

How it is calculated

It is a version 3 UUID, an MD5 hash of the text OfflinePlayer: followed by the username, with the version and variant bits set. Case matters, so Notch and notch give different UUIDs.

This is not a premium UUID

An account that owns Minecraft has a different UUID issued by Mojang. If your server runs in online mode, this tool is not the value you want.

Nothing you type here is stored or sent anywhere. See the other tools.
