How to Find Your Minecraft UUID: Complete Guide 2025

Published on December 29, 2025 by seth

Every Minecraft player has a unique UUID (Universally Unique Identifier). Understanding UUIDs is essential for server owners, plugin developers, and players managing their accounts.

What is a Minecraft UUID?

A UUID is a 32-character hexadecimal string that uniquely identifies your Minecraft account. Unlike usernames, UUIDs never change—even if you change your name.

UUID Format

Full UUID: 069a79f4-44e9-4726-a5be-fca90e38aaf5
Trimmed:   069a79f444e94726a5befca90e38aaf5

Why UUIDs Matter

For Server Owners

• Track players across name changes
• Manage permissions and bans correctly
• Store player data reliably
• Whitelist/blacklist management

For Players

• Verify your identity across servers
• Recover data after name changes
• Check if you’ve been banned
• Link accounts to services

Java vs Bedrock UUIDs

Java Edition

Uses online UUIDs from Mojang servers. Format: Version 3/4 UUID.

Bedrock Edition

Uses Xbox Live GamerTag and XUID instead of traditional UUIDs.

Offline Mode Servers

Cracked/offline servers generate UUIDs from usernames—different from your real UUID!

Common UUID Issues

Lost Data After Name Change?

If a server uses usernames instead of UUIDs, your data might be lost. Good servers always use UUIDs for data storage.

Multiple Accounts?

Each Minecraft account has a unique UUID. Alt accounts have completely different UUIDs.

UUID Mismatch on Servers

If you’re having issues, the server might be in offline mode, generating a different UUID.

UUID for Server Admins

Converting Commands

Many commands accept both formats:

/ban 069a79f4-44e9-4726-a5be-fca90e38aaf5
/whitelist add Notch

Storing Player Data

Always store data by UUID, not username:

playerdata/
  069a79f4-44e9-4726-a5be-fca90e38aaf5.dat
  853c80ef-3c37-49fd-aa49-938b674adae6.dat

Security Considerations

• UUIDs are public information
• Don’t share session tokens
• Verify players with UUID, not just names
• Use UUID for permission systems

Quick Reference

✅ UUIDs are permanent and unique
✅ Usernames can change, UUIDs cannot
✅ Use trimmed UUIDs for URLs/storage
✅ Both formats (dashed/trimmed) are valid
✅ Offline servers use different UUIDs
