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.

Frequently Asked Questions

What does the Minecraft UUID converter do?
It converts a Minecraft username into the player's UUID, or a UUID back into a username. You get both the dashed and trimmed UUID formats plus a preview of the player's skin.
Is the UUID converter free to use?
Yes, the UUID converter is completely free and requires no account or sign-up. You can run as many lookups as you like.
What is the difference between a dashed and trimmed UUID?
Both identify the same player. The dashed format (8-4-4-4-12) is the standard readable form, while the trimmed format is the same identifier without hyphens, which some plugins and files expect.
Where can I get a Minecraft server to go with this?
ValueGameNode hosts Minecraft servers from €3.99/mo for both Java and Bedrock, including mod and plugin support. See live pricing at /buy/.
Does the converter work with new Minecraft accounts?
Yes. The converter pulls data directly from Mojang's official API, so it works with any valid Minecraft username or UUID.
