Minecraft UUID Lookup
Enter any Java Edition username to get the player's UUID and current skin — instantly, no sign-up.
Bulk lookup
Resolve a whole whitelist in one go — lookups run one at a time (300 ms apart) against the same Mojang profile data as the single lookup above.
How to use
- Type a Minecraft Java Edition username (or paste an existing UUID) into the box.
- Press Look up or hit Enter.
- Click the UUID to copy it — both dashed and trimmed formats are shown, plus the player's current skin.
About this tool
Every Minecraft account has a UUID (universally unique identifier) — a 32-character code like 069a79f4-44e9-4726-a5be-fca90e38aaf5 that never changes, even when the player renames. Servers, plugins and mods use UUIDs instead of names for whitelists, bans, permissions and stats, because names can change but UUIDs can't.
This tool resolves any current username to its UUID using Mojang's public profile data, shows the account's current skin, and gives you both UUID formats: dashed (used in most config files and server commands) and trimmed (used by some APIs and databases).
Typical uses: adding players to a whitelist.json, checking who owns a name, setting up per-player permissions, or grabbing a skin for reference.
FAQ
What is a Minecraft UUID?
A UUID is a permanent unique ID assigned to every Minecraft account. Unlike usernames, it never changes — so servers use it to track players across name changes.
Does this work for Bedrock Edition?
No — Bedrock uses XUIDs (Xbox Live IDs), not Mojang UUIDs. This tool covers Java Edition accounts only.
Can I look up name history?
Mojang removed the public name-history API in 2022, so no site can show verified name history anymore. Current name and UUID are always available.
Why do I need the trimmed UUID?
Some databases and APIs store UUIDs without dashes. They are the same value — this page gives you both so you can paste whichever format the software expects.
