What a Minecraft UUID is

Every Minecraft account has a UUID (universally unique identifier): a 32-character token that stays the same even if the player changes their username. Servers, plugins and whitelists identify players by UUID rather than name precisely because the name can change but the UUID does not.

Convert a username to a UUID and back

Enter a username to get the account's current UUID, or enter a UUID to see the name attached to it. The tool shows both the hyphenated (8-4-4-4-12) and the trimmed form. Plugins and config files often require one specific format.

When you need a UUID

A UUID is needed for whitelist.json and ops.json, for ban and permission systems, and for moving per-player data (like inventories and stats) between servers. Name-based identification can break when a player renames. The UUID stays put.
