Player Lookup
Look up a Minecraft Java player by name or UUID: trimmed and full UUID, offline UUID, skin model and skin download.
Look up a Java player by name or UUID
Online and offline UUIDs
Every Java account has a permanent UUID that stays the same when the player changes their name, which is why plugins store UUIDs rather than names. Servers in online-mode=true use this UUID.
Servers in offline mode can’t ask Mojang, so they generate a UUID from the name instead: a version 3 UUID of OfflinePlayer:<name>. It is case-sensitive and changes if the player renames, so data stored under it doesn’t carry over when you switch a server to online mode.
Player heads
Since 1.20.5, item data uses components, so the head is given with [profile=…]. Older versions use the SkullOwner NBT tag. The head shows the player’s current skin, so it changes when they change skin.
