Best Minecraft Seeds for Java 26.3 (Checked In-Game)

Most seed round-ups give you a number and a promise. This one gives you the number, the version it was tested on, and the coordinates of every structure being claimed, so you can check the claim yourself in about two minutes of spectator flight.

Every seed below was loaded in a fresh world on Java 26.3, the current release, on 30 September 2026, and every landmark was checked with /locate in the game itself. The same checks on 26.2 gave the same positions. Where a published coordinate was wrong, the list gives the position the game reported, and claims the game did not confirm were cut.

Read this before you paste a seed

Java Edition stopped using the 1.x scheme. Mojang moved to a year . drop . hotfix numbering system, so the version after 1.21 is not 1.22: it is 26.1, then 26.2 and 26.3. There is no 1.22. Mojang explained the change on the official version numbering announcement.

That matters here because a seed is not a world. It is an input to a world generation algorithm, and when the algorithm changes, the same number produces different terrain. The Minecraft Wiki puts it plainly: whenever world generation is updated, usually by adding biomes, the same seed no longer generates the same terrain. So a seed list is only as good as the version it was checked on.

How to use a seed in Java Edition

On a single player world you set the seed at creation time and never again. There is no command that changes the seed of a world that already exists.

One detail nobody mentions: a purely numeric seed is used exactly as typed, but any seed containing a letter or symbol (other than a leading minus or plus) is hashed through the Java string hash before use. That is why "cheese" and "Cheese" give completely different worlds.

1. 1Click Singleplayer, then Create New World.
2. 2Open the World tab and paste the seed into the Seed for the World Generator field.
3. 3Leave the world type on Default unless a seed says otherwise. Amplified, Large Biomes and Superflat all generate different terrain from the same number.
4. 4Create the world, then press F3 to read your coordinates and navigate to the landmarks below.

Java seeds and Bedrock seeds are not the same thing

This is the single most repeated mistake in seed lists. The truth is more specific than either "they are the same now" or "they are completely different". For 64-bit seeds, terrain and biomes generate the same in both editions, but structures, features, carver caves and mob spawns do not. So a Java seed pasted into Bedrock will usually give you the same mountain and the same mushroom island, and will almost never give you the village at the same coordinates.

That is exactly why the coordinates in our Bedrock seed list are different numbers for similar features. If you play on console, mobile or the Windows version, use that list instead of this one. Everything below is Java only.

Best all-round survival spawns

These are the seeds to pick if you want one world to carry a whole playthrough: food and wood at spawn, a village for beds and trades, and enough underground content that you are never short of a project.

Seed -7417157268905316998: village, ruined portal and trial chamber together

The strongest all-round spawn on this list. A village, a ruined portal about 20 blocks from it and a trial chamber under 60 blocks away, which means beds, trades, your first obsidian and your first real fight are all in the same corner of the map.

The trial chamber is the only one of the four landmarks with a Y value, because it is underground. The other three are on the surface or the sea floor, so X and Z are all you need.

• Version tested: Java 26.3 and 26.2
• Village: X 315, Z 343
• Ruined portal: X 297, Z 340
• Trial chamber: X 294, Y 2, Z 290
• Ocean ruins: X 435, Z 661

Seed -281032838528851848: cherry grove spawn with a village and a trial chamber

You spawn in a cherry grove, so your first wood is not brown. A plains village and a trial chamber sit within about 45 blocks of each other, both about 80 blocks from spawn, with a mineshaft further out.

• Version tested: Java 26.3 and 26.2
• Plains village: X 76, Z 6
• Trial chamber: X 64, Z 48
• Mineshaft: X 17, Z 156

Village and trading hall starts

If the plan is a trading hall, what you want is not one village but several close together, because you need a surplus of villagers to breed from and enough professions to cover mending, protection and the tool enchantments you actually use.

Two villages 200 blocks apart are worth more than one large village, because you can move villagers between them by boat or rail without a nether tunnel. If you have never moved villagers before, our guide to breeding villagers in Minecraft covers the bed and food mechanics that make the hall work.

Seed 302304127329527063: four villages ringing spawn

The best trading hall start here. Four taiga villages sit within about 230 blocks of spawn, close enough that you can walk between them without a compass. A mineshaft, a shipwreck and cold ocean ruins fill in the loot side.

The first village is almost on the spawn point, and all four positions are in the list, so you can walk them in order.

• Version tested: Java 26.3 and 26.2
• Taiga village 1: X 32, Z 16
• Taiga village 2: X -144, Z 0
• Taiga village 3: X 16, Z -160
• Taiga village 4: X -160, Z -160
• Mineshaft: X 32, Z 128
• Shipwreck: X 256, Z -176
• Cave entrance: X -96, Y 8, Z -48
• Cold ocean ruins: X 80, Z -320

Seed 486362209: villages and desert temples in one cluster

A desert start with four villages and two desert pyramids packed into a small area, with mineshafts running underneath. Desert villages give you a quick opening: the houses are sandstone rather than wood, there is no forest cover to clear before you can light the area, and the pyramid TNT is an early source of explosives.

The fourth village is the one you spawn next to, at X 0, Z 0.

• Version tested: Java 26.3 and 26.2
• Village 1: X -192, Z 32
• Village 2: X -144, Z -176
• Village 3: X 48, Z -144
• Village 4: X 0, Z 0
• Desert temple 1: X -136, Z 24
• Desert temple 2: X 24, Z -232

Seed -3361685360695458093: a quad village that reads as one town

Four villages generate at the corners of a square 144 blocks on a side, close enough to join into one town. Useful if you would rather build a town than manage a logistics network between four of them. There is a trial chamber within 200 blocks of spawn and an ancient city about 1,000 blocks out for the endgame.

• Version tested: Java 26.3 and 26.2
• Quad village: X -144 Z 0, X 0 Z 0, X -144 Z -144, and X 0 Z -144
• Trial chamber: X 185, Y -27, Z 71
• Ancient city: X 807, Y -51, Z 567
• Ruined portal: X 23, Z 364
• Buried treasure: X -1031, Z -727

Strongholds and end portals: what is actually possible

Every few months a list promises a "stronghold at spawn" in Java. It is not possible. Java generates exactly 128 strongholds arranged in 8 concentric rings around the world origin, and the innermost ring starts at 1,280 blocks out. Nothing generates closer. Any Java seed advertising an end portal within a few hundred blocks of spawn is either a Bedrock seed relabelled or simply wrong.

So the honest framing is not "stronghold at spawn" but "shortest realistic walk to an end portal". Here is the ring layout, which also tells you how far you need to throw eyes of ender before you should worry:

Seed -4496590507308278848: stronghold, ancient city and igloo together

The most efficient end portal run on this list. About 1,600 blocks from a bamboo jungle spawn, a basement igloo sits about 100 blocks from a stronghold, and an ancient city is 200 blocks south of the stronghold, so one trip gets you the portal room, the echo shards and the disc fragments. A nether fortress sits about 100 blocks from the Nether side of a portal built at the stronghold.

The stronghold at X 548, Z 1540 is about 1,630 blocks from origin, which puts it near the inner edge of ring 1 in the table above. That is roughly as close to spawn as a Java stronghold can generate.

• Version tested: Java 26.3 and 26.2
• Stronghold: X 548, Z 1540
• Ancient city: X 548, Z 1736
• Igloo with basement: X 648, Z 1544
• Nether fortress: X 126, Z 274 in Nether coordinates

Rare biome clusters

Mushroom fields, cherry groves and ice spikes are the three biomes people restart worlds looking for. Mushroom fields are worth the most: it is the only biome where hostile mobs do not spawn naturally on the surface, which makes it the safest base location in the game and the one place you can skip lighting entirely.

Seed 4405134068028: mushroom fields and seven other biomes near spawn

The widest biome spread on this list. Eight distinct biomes fall inside about 1,260 blocks of spawn, and four of them are inside 600.

Pick this one if you want spruce, dark oak and cherry wood, terracotta, sand and mooshrooms in one region instead of behind a nether highway. All positions are X and Z only.

• Version tested: Java 26.3 and 26.2
• Mushroom fields: X -288, Z -112
• Dark forest: X 192, Z 112
• Old growth pine taiga: X 150, Z 150
• Cherry grove: X 752, Z 81
• Swamp: X -240, Z -662
• Desert: X 950, Z -777
• Badlands: X 819, Z -891
• Snowy plains: X -731, Z 971

Seed 69420018030897796: a village in a lake basin below cherry groves

A plains village sits in a bowl of water, with cherry groves on the high ground around it. You spawn in one of them, about 125 blocks from the village, and a second grove is about 90 blocks away on the other side.

• Version tested: Java 26.3 and 26.2
• Plains village: X 64, Z 48
• Cherry grove: X 128, Z 112

Seed 105849523: snowy village beside ice spikes

A snowy village start with ice spikes about 70 blocks away. You spawn essentially on top of the village, with frozen ocean beyond, a spider dungeon underneath and a lava pool cave for early obsidian.

• Version tested: Java 26.3 and 26.2
• Snowy village: X 2, Z -9
• Ice spikes: X 64, Z 32
• Spider dungeon: X -50, Y -16, Z -39
• Lava pool cave: X 144, Y -56, Z -32
• Igloo with basement: X 8, Z 568
• Ruined portal: X 64, Z -336

Seed 1606377695512438131: an ancient city directly under spawn

You spawn on top of a deep dark: the world spawn point is at Y -21, and the ancient city fills the space directly below it, from Y -52 to Y -22. That makes this the shortest run to echo shards, disc fragments and armor trims on this page.

Treat it as a loot target, not a horror set piece. If atmosphere is what you are after instead, our scariest Minecraft seeds list picks worlds for how they feel rather than what they contain.

• Version tested: Java 26.3 and 26.2
• Ancient city: X 0, Z 0, directly under spawn from Y -52 to Y -22
• Cherry grove village: X 173, Z -12
• Mineshaft: X -80, Y -36, Z -33
• Trial chamber: X -238, Y -16, Z -20

Seed 934598: sulfur caves breaking through the surface

The only seed here that comes from Mojang's bug tracker rather than from a seed list. Sulfur caves are new in 26.2: a cave biome of sulfur, cinnabar and sulfur spikes, generating in the same depth band as lush caves and dripstone caves. They are configured for weirdness values between -1.1 and -0.85, and no other biome uses anything below -1.0, so where the noise dips far enough the sulfur cave has nothing to compete with and takes over the surface.

Someone filed that as a bug on Mojang's issue tracker with a one-line reproduction: create a world with seed 934598 and teleport to 0, 70, 0. Mojang closed it as Works As Intended, and the behaviour shipped in the release, so surface sulfur caves are a rare find rather than a defect.

• Version tested: Java 26.3 and 26.2, reported against 26.2 snapshots
• Surface sulfur caves: teleport to X 0, Y 70, Z 0

Structure-rich seeds

If you have played enough survival worlds that the early game bores you, structure density is the thing to optimise for. Two facts make these seeds easier to read.

An ancient city generates at Y -51. That depth is a property of the structure, not of the seed, which is why almost every ancient city coordinate you have ever seen lands within a block or two of the same number. Published figures that read -52, -49 or -48 are people quoting the block they were standing on. A figure nowhere near it is describing something else, and one below Y -64 is describing nothing at all, because that is the bottom of the world.

Trial chambers are on a fixed grid. Added in 1.21, they place roughly one per 34 by 34 chunk region measured from X 0, Z 0, in any Overworld biome except the deep dark. The starting room generates between Y -40 and Y -20 and most other rooms sit between Y -20 and Y 0, so if you are at the right X and Z and finding nothing, you are usually at the wrong depth rather than the wrong place. They are also the only place breezes spawn naturally.

Seed 111111111111111111: 40 ancient cities within 5,000 blocks

Forty ancient cities generate within 5,000 blocks of spawn, which is enough sculk, echo shards and armor trims for an entire server. The nearest two are both about 785 blocks out, and at that density you will trip over the rest.

A practical warning: sculk shriekers summon the Warden, and 40 cities means 40 chances to get that wrong. Carry a stack of wool. Sculk sensors cannot hear you walk on wool, and a wool block between a sensor and the chest you open blocks that vibration too, which is the difference between looting a city and leaving it.

• Version tested: Java 26.3 and 26.2
• Ancient city: X -672, Z 400
• Ancient city: X -320, Z -720
• Village: X 0, Z -464
• Mineshaft: X -203, Y -26, Z -653

Seed 184290855362048334: six ancient cities plus a cheese cave

A smaller version of the above with more variety on the way down: six ancient cities within about 650 blocks of spawn, a cheese cave for a base, a trial chamber and a zombie dungeon for a spawner farm.

• Version tested: Java 26.3 and 26.2
• Ancient city: X -157, Y -48, Z -148
• Cheese cave: X -32, Y 40, Z 192
• Trial chamber: X 265, Y -17, Z 57
• Zombie dungeon: X 69, Y -28, Z -29

Seed 844424960210770: woodland mansion on top of spawn

Woodland mansions normally generate far from spawn, which is why most players see their first one only after trading for an explorer map. This one straddles a river essentially at spawn.

The value is the totem of undying from the evokers, and the fact that a cleared and lit mansion is a finished multi-floor base you did not have to build. There is a trial chamber and a mineshaft nearby for the rest of the loot loop.

• Version tested: Java 26.3 and 26.2
• Woodland mansion: X 24, Z 8
• Trial chamber: X 55, Y -22, Z 281
• Mineshaft: X 264, Z -104
• Village: X 256, Z -960

Seed -9215772017318341931: four witch huts around a mansion

Four swamp huts generate in a rough ring around a woodland mansion. Witches spawn inside swamp huts, so each hut can hold a witch farm, and the mansion in the middle gives you the totems. Redstone, glowstone dust and gunpowder from one build, with an evoker source next door.

• Version tested: Java 26.3 and 26.2
• Woodland mansion: X 504, Z 456
• Witch huts: X 360 Z 376, X 376 Z 520, X 536 Z 536, and X 536 Z 344

Seed 8110137054462309706: pillager outpost between two villages

A savanna village east of spawn, a pillager outpost a few hundred blocks south of it, a ruined portal past that, and a second village beyond. Outposts near villages mean raids are easy to trigger and easy to farm, and this layout gives you two raid targets and an outpost for the ominous bottles that start them.

• Version tested: Java 26.3 and 26.2
• Savanna village: X 225, Z 0
• Pillager outpost: X 215, Z 261
• Ruined portal: X 347, Z 242
• Second village: X 523, Z 266
• Cherry grove: X 202, Z -382
• Bamboo jungle: X 524, Z -299

Speedrun-friendly seeds

A speedrun seed is not a seed with good loot. It is a seed where the three fixed bottlenecks (obsidian, blaze rods, ender pearls) and the stronghold are all short walks apart.

Seed -4496590507308278848, covered above, is the strongest current-version option on this page: the igloo basement, the stronghold and the ancient city sit within about 220 blocks of each other, and the nether fortress is about 100 blocks from a portal built at the stronghold. That is the whole run without a search phase.

The famous set-seed runs are 1.16 seeds, not 26.3 seeds

Two seeds appear on nearly every speedrun list, including several that label them as current. They are not. Both are 1.16-era seeds, and 1.16 world generation predates the cave and cliffs rewrite, the deep dark, trial chambers and sulfur caves. Checked in 1.16.1, every coordinate below holds there; in 26.3 only the second seed's Nether fortress is still in place.

They are still worth running if you want to race the same world the record runs used. Just set your launcher to 1.16.1 first.

Every coordinate on this page in one table

All checked in Java 26.3 and 26.2. Where a cell reads n/a, only X and Z were confirmed, which is all you need for a structure on the surface. Nether coordinates are labelled in the landmark column, and are not interchangeable with Overworld ones.

Using a chosen seed on a multiplayer server

On a server the seed lives in server.properties, in the level-seed field. It is blank by default, and a blank field means a random seed. The companion setting is level-type, which stays on minecraft:normal unless you want large biomes or superflat.

The critical part: level-seed is read only when the world is generated for the first time. Setting it on a server that already has a world does nothing at all. The server reads the existing world folder, ignores the property, and you will spend an hour convinced the seed is broken.

One more operational detail specific to the current versions. Minecraft 26.1 and newer require Java 25, not Java 21. If you are running your own hardware, check your runtime before blaming the seed for a server that will not start.

Applying a seed to a new server

On a fresh server this is three steps and takes about a minute. If you have not set a server up before, our guide to making a Minecraft server covers the rest of the process.

1. 1Create the server but do not start it yet.
2. 2Open server.properties and set the seed, exactly as written.
3. 3Start the server. The world generates from your seed on that first boot.

Regenerating an existing server on a new seed

Because the property is ignored once a world exists, changing seeds on a live server means deleting the world first. This destroys everything anyone has built, so take a backup before you touch anything, and tell your players.

Do this in order. If you delete the Overworld folder but leave world_nether in place, you get a Nether that no longer lines up with the Overworld above it, and portals start linking to the wrong places.

1. 1Stop the server. Do not do this while it is running: the world is written on shutdown and you will get a half-saved folder.
2. 2Take a full backup. On CraftLands you make one from the Backups section of the panel, covered in creating a server backup.
3. 3Delete or rename the world folder, plus world_nether and world_the_end. Renaming is safer than deleting if you might want the old world back.
4. 4Set level-seed to your new seed and save the file.
5. 5Start the server. Watch the console: the world generates from scratch, which takes longer than a normal boot.

Pre-generate before you let people in

Worth doing on any server, and especially on the structure-dense seeds above, because those are the ones where players sprint 2,000 blocks in a straight line on day one. Generating chunks while players explore makes the server build terrain on the fly, and generating them in advance lets it load that terrain from disk instead. How to pre-generate a Minecraft world walks through it. If the console still prints "Can't keep up! Is the server overloaded?" while people explore, paste a spark profile into our spark report analyzer to see what is using the tick time.

Also lock your server version. Each drop can change world generation for chunks that do not exist yet: a 26.2 world updated to 26.3 can grow dappled forests and abandoned camps at its edges while the explored area keeps its old terrain. Changing your server version is a deliberate action for exactly this reason.

If you want the world to exist whether or not your computer does, our Minecraft server hosting runs on the AMD Ryzen 9 9950X with NVMe storage and deploys in under a minute. You set level-seed before first boot and the world is the one you picked.

How to check a seed before you commit to it

Ten minutes of verification saves a restart forty hours in. The process that actually works:

1. 1Create a throwaway world on the seed in creative mode with the same version you plan to play.
2. 2Fly to the coordinates you care about in spectator. Structures load at render distance, so fly high.
3. 3Confirm the two or three landmarks you actually care about, not all of them. If the village and the stronghold are where they should be, the rest of the list is probably fine.
4. 4Delete the throwaway world and create your real one on the same seed.

A note on seed map sites

Online seed maps are the fastest way to check a claim, and Chunkbase updated its map for 26.3 on 15 September 2026. Use them, with one caveat that its own developers state: many features are not 100 percent accurate, and locations can be wrong or missing, dungeons and world spawn positions among them.

So a seed map is a good way to disprove a claim quickly and a mediocre way to prove one. If the map shows nothing at all where a village should be, the seed is probably wrong. If it shows one, still fly there.

Frequently Asked Questions

Where to go next

Pick one seed, verify the two landmarks you actually care about in a throwaway creative world, then start for real. Chasing a perfect spawn is how worlds get restarted rather than played.

If the plan is a world with friends in it, set level-seed before the first boot, pre-generate the area around spawn, and keep the server on one version so the seed keeps generating the world you chose.
