Bedrock Edition — XUID & Floodgate UUID
Bedrock players don’t have a Mojang UUID. Convert an Xbox gamertag to its XUID and the Floodgate UUID that Geyser/Floodgate servers use for whitelists and bans.
Username ↔ UUID, and why it matters
Every Minecraft account has a permanent UUID. Because players can change their username, servers key everything — whitelist entries, bans, permissions (LuckPerms), economy and player data files — to the UUID instead. When you need to whitelist or ban someone who isn't online, or edit a playerdata/<uuid>.dat file, this is how you find the right ID.
Dashed vs undashed
The undashed form is 32 hex characters; the dashed form groups them 8-4-4-4-12. Some plugins/config files expect dashes and others don't — both are provided so you can copy the exact format you need.
A note on name history
Mojang removed the public name-history API in September 2022, so no lookup tool can reliably show a player's previous usernames anymore — only the current name resolves to a UUID.
FAQ
What is a Minecraft UUID?
A UUID is the unique 32-hex-digit identifier Mojang assigns to every account. Servers use it instead of the username, because usernames can change but the UUID never does — so bans, permissions and player data stick to the right person.
How do I convert a username to a UUID (or back)?
Type a username or a UUID into the box above and search — you land on that player’s page with the username, the undashed UUID and the dashed UUID, plus their skin.
What’s the difference between the dashed and undashed UUID?
They are the same value. The dashed form (8-4-4-4-12) is used by some plugins and config files; others want it without dashes. Both are shown so you can copy whichever you need.
Do offline / cracked servers use the same UUID?
No. Offline-mode servers generate a UUID from the name (an MD5 of "OfflinePlayer:<name>"), so it differs from the player’s official online UUID. Use the offline UUID generator for those.
Why isn’t name history shown anymore?
Mojang shut down the public name-history API in September 2022. No tool can reliably list a player’s past usernames now — only the current name resolves.
Can I use the skin images directly?
Yes — the head, body, raw skin and cape texture URLs are copyable and can be hot-linked, e.g. on a website or scoreboard service.
Can a Minecraft UUID change?
No — a UUID is permanent for the life of the account, even when the player changes their username. That’s exactly why servers tie whitelists, bans and permissions to the UUID instead of the name.
How do I find a Bedrock player’s UUID?
Bedrock uses an Xbox XUID, and Geyser/Floodgate servers derive a Floodgate UUID from it. Use the Bedrock Edition box on this page to convert a gamertag to its XUID and Floodgate UUID.
