XUID lookup

An XUID (Xbox User ID) is the number Xbox Live gives every account. Minecraft Bedrock uses it to tell players apart. It never changes, even when the player changes their gamertag, so servers use it for bans, whitelists and stats.

Floodgate lets Bedrock players join Java servers through Geyser. It gives each Bedrock player a Java-style UUID built from their XUID: the first 16 hex digits are zeros and the last 16 are the XUID in hexadecimal, for example 00000000-0000-0000-0009-01f063c12ed3.

Yes. Paste the XUID (decimal or hex) or the Floodgate UUID into the box and the tool shows the gamertag the account has today.

Type your gamertag here. The result shows your XUID in decimal and hex, and your Floodgate UUID.

Minecraft shows spaces in a gamertag as underscores, so Gongju Yuna appears as Gongju_Yuna. Both forms work in this tool.
