Minecraft UUID lookup

Type a Java Edition username to get its UUID, the permanent ID servers use for whitelists, ops and player data.

The exact username of a Java Edition account. Capital letters do not matter.

How this works

Every Java Edition account has a permanent UUID. Servers use it for whitelists, ops and player data, because usernames can change but the UUID never does. This tool asks Mojang for the UUID that goes with a username. Servers in offline mode make up their own UUIDs, so those will not match.
