Finding custom experiences in Fortnite shouldn't feel like guessing a password. Whether you're hunting for aim training courses, horror maps, or custom 1v1 arenas, entering Fortnite map codes correctly is the key to unlocking millions of player-created islands. If you've ever stared at a blank island code screen wondering where the numbers go, here is the exact, no-nonsense way to use them.
Fortnite map codes (also known as Island Codes) are 12-digit numeric sequences assigned to unique creations built in Creative mode or Unreal Editor for Fortnite (UEFN). When you enter a valid code, the game loads that specific custom map directly into your matchmaking session. Epic Games hosts millions of these islands, ranging from box fights to open-world adventures.
Where to Find the Island Code Menu
Before you can type in a code, you need to open the right menu inside Fortnite. The layout changes slightly depending on whether you're playing solo or with a party, but the destination is always the same.
- Launch Fortnite and head to the main lobby.
- Open the mode selection screen by clicking the Change button above the "Play" button.
- Navigate across the tabs at the top to find the Island Code tab (sometimes listed under "By Epic" or search filters).
- Click on the text box that says Search/Code or Island Code.
You can also access this menu from the Discover tab by clicking the search icon in the top right corner of your screen.
How to Enter and Play a Map Code
Once you have the text box open, entering the code is straightforward, but formatting errors will cause an error message.
- Type the 12-digit code into the search box. Make sure you include the hyphens if the creator formats them that way, though most modern entry fields accept continuous numbers or auto-format them. For example, a standard code looks like
1234-5678-9012. - Press Enter on your keyboard or select Confirm on controller.
- The UI will update to display the title, creator name, and a preview thumbnail of the map. Verify this is the exact map you want.
- Click Favorite if you want to save it for later, or click Play to start loading the session.
- Set your matchmaking to Private if you want to explore alone or practice without random players joining your lobby.
According to Epic Games Creator Guidelines, island creators publish their work through the Island Creator Program, ensuring that official codes link directly to verified server instances.
Troubleshooting Common Map Code Errors
Sometimes a code won't load, leaving you stuck in the lobby. Here is why that happens and how to fix it:
- Typo in the numbers: Even a single digit out of place will result in a "Code not found" error. Double-check your source.
- Outdated map versions: Creators update their maps frequently. If an older version of a map was unpublished or replaced by the creator, the old code stops working.
- Matchmaking restrictions: Some maps require a full lobby or specific player counts to start. If you're trying to launch a squad game solo, the map might block you from queuing.
- Client desync: If the game hasn't updated to the latest patch, newly released maps may fail to appear. Restart your game client to force an update check.
Managing Your Favorite Map Codes
If you find a map you love, you don't need to write the 12-digit code down on a sticky note. Fortnite lets you curate your own library.
- Open the Discover screen and search for the map code.
- Click the heart icon on the map tile to add it to your My Library tab under Favorites.
- To check your saved maps later, simply open the Discover menu and scroll to your personal library category.

No. Custom maps built in Creative and UEFN are entirely free to access for all players, regardless of whether you own the current Battle Pass.
How do I create my own map codes?
