How to Find Your Minecraft UUID

Last updated: March 2026 · 4 min read

Your Minecraft UUID is a unique identifier tied to your account that never changes, even when you change your username. There are several ways to find it, from using an online tool to digging through game files. This guide covers all the common methods.

Method 1: Use Our Online Lookup Tool (Easiest)

The fastest way to find any player's UUID is to use the search tool right here on MinecraftUUID.com. Simply type a username into the search box below and press Enter:

The results page will display the player's full UUID (with hyphens), trimmed UUID (without hyphens), account creation date, current skin render, and name history. You can click on either UUID to copy it to your clipboard.

Method 2: In-Game Debug Screen (F3)

If you're currently logged into Minecraft Java Edition, you can find your own UUID using the debug screen:

  1. Launch Minecraft Java Edition and load into any world (singleplayer or multiplayer).
  2. Press F3 on your keyboard to open the debug screen (on some laptops, you may need to press Fn + F3).
  3. Look at the top-left section of the debug overlay. Your UUID is displayed on one of the first few lines, typically in the format UUID: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.

Note that the debug screen only shows your own UUID. To find another player's UUID, you'll need to use one of the other methods.

Method 3: Minecraft Launcher Files

Your UUID is stored in a file on your computer by the Minecraft launcher:

  1. Navigate to your .minecraft folder:
    • Windows: %appdata%\.minecraft
    • macOS: ~/Library/Application Support/minecraft
    • Linux: ~/.minecraft
  2. Open launcher_profiles.json in a text editor.
  3. Find the "id" field under your account entry. This is your UUID (it may appear without hyphens).

Method 4: Server Player Data Files

If you're a server administrator, player UUIDs are stored in player data files:

  • Player data is stored in world/playerdata/ as <uuid>.dat files.
  • The server's usercache.json file maps usernames to UUIDs for all players who have joined the server.
  • The whitelist.json and banned-players.json files also contain UUID-to-username mappings.

Method 5: Query the Mojang API Directly

For developers or technical users, you can query the Mojang API directly using any HTTP client:

# Get UUID from username

GET https://api.mojang.com/users/profiles/minecraft/<username>

The response will include the player's UUID (in trimmed format) and current username.

Tips and Notes

  • UUIDs are not case-sensitive - 069A79F4 and 069a79f4 refer to the same account.
  • If you recently changed your username, your UUID stays the same. Servers and tools using UUIDs will still recognize you.
  • This tool and the Mojang API only work for Java Edition accounts. Bedrock Edition uses Xbox Live gamertags and XUIDs instead.
  • Some servers run in "offline mode" and generate their own UUIDs based on usernames. These offline UUIDs won't match the Mojang-assigned UUID.
