Minecraft UUID Lookup
Look up a Minecraft player's UUID from their username using the Mojang API. Get both the trimmed and dashed UUID formats.
How to Use the UUID Lookup Tool
Enter any Minecraft Java Edition username in the search field and click "Look Up UUID" or press Enter. The tool queries the official Mojang API to retrieve the player's UUID (Universally Unique Identifier). Results include the player's current username, their avatar, and the UUID in both standard dashed format and trimmed format without dashes.
Each copy button places the corresponding value directly on your clipboard, ready to paste into server configuration files, plugin configs, whitelists, or ban lists. The dashed format (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx) is used by most server software and plugins, while the trimmed format is what Mojang uses internally and in their API responses.
Common Use Cases
Server administrators frequently need player UUIDs for whitelist management, permission configuration, and player data lookups. Since Minecraft 1.7.6, the game uses UUIDs instead of usernames to track players. This means a player can change their username but their UUID stays the same, so server configs that reference UUIDs will always point to the correct player.
Plugin developers use UUIDs to store player data persistently. Whether you are building a custom economy system, tracking statistics, or implementing a friend list, UUIDs ensure your data stays tied to the right player even after name changes. This tool makes it simple to test and verify UUID lookups during development.
The skin URL output is a bonus for web developers building player profiles or status pages. You can embed the avatar image directly using the provided URL to display player heads on your website, forum, or Discord bot.
