What is a Minecraft Seed?
A Minecraft seed is a numeric or alphanumeric value used to generate a specific world in Minecraft. The seed controls the procedural terrain generation algorithm, determining biome placement, structure locations (villages, temples, strongholds), ore distribution, and landscape features. The same seed will always generate the same world, making seeds perfect for sharing interesting worlds or speedrunning.
Minecraft Java Edition uses 64-bit signed long integers (range: -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807), while Bedrock Edition uses 32-bit signed integers (range: -2,147,483,648 to 2,147,483,647). Our generator creates cryptographically random seeds compatible with both editions. For other random data needs, try our number generator or UUID generator.

[STEP 1] Paste Seed
Paste the copied seed into the "Seed" field and click "Create New World" to generate that specific world.
Common Use Cases for Minecraft Seeds
- _ Exploration & Discovery: Generate random seeds to discover unique biomes, terrain features, and structures
- _ Speedrunning Practice: Generate multiple seeds quickly for speedrun attempts and finding optimal spawn locations
- _ Creative Building: Find seeds with specific terrain features perfect for building projects (mountains, islands, valleys)
- _ Multiplayer Servers: Generate unique seeds for server worlds, ensuring fresh experiences for players
- _ Content Creation: Streamers and YouTubers use random seeds for "blind playthrough" videos and challenges
- _ Seed Sharing: Share interesting generated seeds with the Minecraft community via Reddit, Discord, or forums
Technical Details: Minecraft Seed Generation Algorithm
Our Minecraft seed generator uses cryptographically secure random number generation (CSPRNG) to produce seeds within the valid ranges for Java Edition (64-bit long) and Bedrock Edition (32-bit int). The generator ensures uniform distribution across the entire range, meaning every possible seed value has equal probability of being selected. This guarantees maximum terrain variety and prevents any bias toward specific world generation patterns.
// Java Edition Seed Generation (64-bit signed long) Range: -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 Algorithm: CSPRNG with uniform distribution seed = random_long_int(-2^63, 2^63 - 1) // Bedrock Edition Seed Generation (32-bit signed int) Range: -2,147,483,648 to 2,147,483,647 Algorithm: CSPRNG with uniform distribution seed = random_int(-2^31, 2^31 - 1) // Minecraft uses these seeds in procedural generation: World world = new World(seed); // Terrain generation uses seed as input to: // - Perlin noise for terrain height // - Simplex noise for biome distribution // - Structure placement algorithms // - Cave/ravine generation // - Ore distribution Security: CSPRNG ensures unpredictable, non-repeating seeds Distribution: Uniform across entire valid range Compatibility: Java 1.7+, Bedrock all versions

Can I use the same seed on different devices? ▶
How do I find the seed of my current world? ▶
/seed in the chat (requires cheats enabled or operator permissions). In Bedrock Edition, open Settings → Game → Show Coordinates (scroll down to see seed). Alternatively, check the world creation screen or use third-party tools like NBTExplorer to view the seed in your save files.
