How To Change The Seed On Your Terraria Server - Terraria Guide

This guide will help you modify the world seed on your Terraria server. Seeds determine how the world generates, allowing you to share or replay specific world layouts, or enable secret world modifiers.

Changing The World Seed

Changing a world seed requires the creation of a new world!

Log in to the GhostCap Panel and Stop your Terraria server.
Navigate to File Manager and open config.txt.
Locate the seed setting, modify it to your desired seed, and save.
In the sidebar, access Server Options.
Under Basic, change World Name to generate a new world.
Go to Console and Start your server.

Special World Seeds

Terraria has several special world seeds that generate unique worlds with modified mechanics and features. These seeds work on dedicated servers and can be entered exactly as shown below.

Seed	Description
`5162020`	Drunk world. Generates both Corruption and Crimson with both ore variants.
`not the bees`	Replaces most of the world with Jungle, Hive, and Honey Blocks.
`for the worthy`	Drastically increases difficulty with modified boss AI and enemy stats.
`celebrationmk10`	Paints the world in bright colors with increased rare item drop rates.
`the constant`	Don't Starve crossover. Adds hunger, darkness mechanics, and a darker shader.
`no traps`	Despite the name, generates significantly more traps than a normal world.
`dontdigup`	Flips the world, spawning the player in the Underworld.
`getfixedboi`	Combines all secret seeds into one world with upscaled difficulty.

Secret World Seeds (1.4.5+)

Terraria 1.4.5 added a large set of secret world seeds. A full list can be found on the Terraria Wiki.

Caution

Secret world seeds will not work if you only type the seed name. On a dedicated server, the World Size, Difficulty, and the entire seed code including the version prefix (for example 3.1.2.0.winteriscoming|1378921490) must all match what the Terraria menu generates, otherwise world generation will conflict or fall back to a normal world.

Using A Secret Seed On Your Server

Open Terraria on your PC, go to Single Player > New, and start creating a world with your desired World Size and Difficulty.
Enter the secret seed name in the seed field, then copy the full seed code that Terraria shows (it will look like 3.1.2.0.winteriscoming|1378921490).
Log in to the GhostCap Panel and Stop your Terraria server.
In the sidebar, go to Server Options and set World Size and Difficulty to the same values you chose in step 1.
Paste the full seed code into the World Seed setting (this is the same value as seed in config.txt), and change World Name so a new world is generated.
Go to Console and Start your server.

If you would rather avoid world generation issues entirely, create the world with your desired seed in singleplayer and then upload the save to your server using our Upload Save guide.

You can also unlock every secret seed in singleplayer at once by entering the following code, provided by the Terraria Wiki, in the seed field:

1.1.1.0.abandoned manors|arachnophobia|beam me up|bring a towel|double daring dangers|fish mox|hocus pocus|how did i get here|i am error|invisible plane|jagged rocks|jingle all the way|mole people|monochrome|more traps please|negative infinity|night of the living dead|planetoids|pumpkin season|purify this|rainbow road|royale with cheese|does that sparkle|too easy|water park|what a horrible night to have a curse|winter is coming|xray vision|truck stop|sandy britches|save the rainforest|such great heights|the care bears movie|toadstool|we don't even test for that|
