¿Qué es un UUID de Minecraft?

UUID = Identificador Único Universal — una cadena hexadecimal de 32 caracteres que nunca cambia.

Every Java Edition player has a UUID assigned by Mojang. It looks like 853c80ef3e3740fdaa867b06307a3d4f (no hyphens) or 853c80ef-3e37-40fd-aa86-7b06307a3d4f (with hyphens).

Why it matters: Usernames can change. UUIDs cannot. Servers use UUIDs for banned-players.json, whitelist.json, and ops.json so bans and whitelists stay correct even when a player renames.

Format: Java UUID can be 853c80ef3e3740fdaa867b06307a3d4f (32 hex chars, no hyphens) or 853c80ef-3e37-40fd-aa86-7b06307a3d4f (with hyphens). Both work.

¿Qué es XUID (Bedrock)?

XUID is the unique ID for Bedrock Edition players — Xbox, mobile, Windows 10, Nintendo Switch. It's a long decimal number (e.g. 2535412345678901).

Floodgate UUID: For GeyserMC cross-play servers, Bedrock players get a special Floodgate UUID that starts with 00000000-0000-0000. Our lookup returns both XUID and Floodgate UUID for Bedrock players.

Quick reference: Java = UUID (32 hex). Bedrock = XUID (decimal). GeyserMC = Floodgate UUID (starts with 00000000). All three are different — use the right one for your server type.

Paso a Paso: Encontrar un UUID

Cuatro pasos simples. Sin cuenta, sin clave API, sin límites.

1
Open the Profile Lookup — Go to vrc.lol/player. Our free Minecraft profile lookup. Works for Java and Bedrock.
2
Enter username or UUID — Type the player's Java username (e.g. Notch, Technoblade), Bedrock gamertag, or an existing UUID to reverse-lookup.
3
View the results — See UUID (Java), XUID (Bedrock), Floodgate UUID, name history, skin, and cape. Copy any value with one click.
4
Use the data — For Java: add to banned-players.json, whitelist.json, or ops.json. For Bedrock: use our JSON List Wizard to generate permissions.json, allowlist.json, banned-players-bedrock.json.
Tip: Use our API to fetch UUID programmatically — GET https://vrc.lol/api?username=Notch returns JSON with the UUID.
Consejos
  • Always use UUID for bans — Never ban by username. If a player renames, a username-based ban won't work.
  • Java vs Bedrock — Java uses UUID; Bedrock uses XUID. They're different. Our lookup returns both when available.
  • GeyserMC cross-play — Use the Floodgate UUID for Bedrock players joining Java servers via GeyserMC.
Errores comunes
  • Banning by username — Bans won't persist if the player renames. Always use UUID.
  • Mixing Java and Bedrock IDs — UUID for Java servers, XUID for Bedrock. Don't use them interchangeably.
  • Wrong file format — Java uses banned-players.json; Bedrock uses banned-players-bedrock.json. Different structure.

Casos de Uso

Lo que puedes hacer con un UUID de Minecraft:

  • Ban a player — Add UUID to banned-players.json. The ban persists even if they change their username.
  • Whitelist — Add UUID to whitelist.json so only approved players can join.
  • Ops — Add UUID to ops.json to grant operator permissions.
  • Plugins & mods — Many plugins need UUID to identify players (economy, permissions, etc.).
  • Discord bots — Link Discord accounts to Minecraft via UUID.
  • Leaderboards — Store UUID instead of username so name changes don't break stats.

Listas JSON y Servidores Bedrock

Our JSON List Wizard builds server config files from lookups. No manual editing.

Java Edition

Export to banned-players.json, whitelist.json, or ops.json. One click adds a player with correct UUID format.

Example banned-players.json entry: { "uuid": "853c80ef3e3740fdaa867b06307a3d4f", "name": "jeb_", "source": "Server", "expires": "forever", "reason": "Banned" }

Example whitelist.json entry: { "uuid": "853c80ef3e3740fdaa867b06307a3d4f", "name": "jeb_" }

Where files go: Place in your server's root folder (same level as server.properties). Restart the server or use /whitelist reload / /banlist to apply.

Bedrock Edition

Generate permissions.json (operator, member, visitor), allowlist.json, and banned-players-bedrock.json. Enter Xbox gamertags — we fetch XUIDs automatically. Add Floodgate UUID for GeyserMC cross-play.

Preguntas Frecuentes

¿Qué es un UUID de Minecraft?
A UUID (Universally Unique Identifier) is a 32-character hex string that uniquely identifies a Java Edition player. It never changes, even if the player changes their username.

¿Qué es XUID para Bedrock?
XUID is the unique ID for Bedrock Edition players (Xbox, mobile, Windows 10). Our tool returns it in both decimal and hexadecimal formats.

¿Qué es un UUID Floodgate?
A Floodgate UUID is used by GeyserMC Floodgate to represent Bedrock players on Java servers. It starts with 00000000-0000-0000 and includes the player's XUID. We provide it for cross-play setups.

¿Es gratis?
Sí. La Búsqueda de Perfil Minecraft y el Generador de Listas JSON son 100% gratis. Sin registro, sin clave API, sin límites.

¿Cómo añado un jugador a banned-players.json?
Look up the player at vrc.lol/player, then use the JSON List Wizard to add them with one click. Or copy the UUID and add it manually.

¿Cambia el UUID cuando un jugador cambia su nombre?
No. El UUID de Java nunca cambia. Por eso los servidores usan UUID para bans y whitelists — los nombres pueden cambiar, los UUID no.

¿Debo banear por nombre de usuario o UUID?
Always use UUID. Usernames can change; UUIDs cannot. A ban by username will fail if the player renames. Our JSON List Wizard adds the correct UUID automatically.

¿Y si el jugador no existe?
Revisa la ortografía. Los nombres de usuario de Java tienen 3–16 caracteres. La cuenta puede estar inactiva o ser solo de Bedrock — prueba buscando por gamertag de Xbox.

¿UUID con o sin guiones?
Both work. 853c80ef3e3740fdaa867b06307a3d4f (no hyphens) and 853c80ef-3e37-40fd-aa86-7b06307a3d4f (with hyphens) are valid. Minecraft accepts both.
