Fortnite Custom Matchmaking 2026
Host a private Battle Royale session with the right creator access, a clean Custom Key, one shared server region and a join flow your players can follow.
The host needs creator-program access; everyone needs the same supported Battle Royale mode, region and exact key.
A host with completed creator setup selects an eligible Battle Royale mode, makes sure all players use the same server region, opens Custom Key and creates a 4-16 character key with no special characters. Participants enter that case-sensitive key, press Play and wait for the host to Start Match.
Creating a Custom Match is not an all-player lobby option.
Epic says hosting Custom Matches is available to active members of its creator or developer programs. Even a program member must complete the account creator setup process before the host flow becomes available.
Creating Custom Matches is currently limited to accounts active in one of Epic's creator or developer programs.
Membership alone is not enough. Epic says the account creator setup must be completed before a member can host.
Players join with the host's Custom Matchmaking Key and must use the same server region and game mode.
Use one simple, private key that every participant can type exactly.
The key is the shared entry point, so its format matters. Epic's current rules are narrow: it must be 4-16 characters long, cannot use special characters and is case sensitive when players join.
Epic reports an error when the key is too long. Use a short, readable string that fits the host's audience.
Keep the key to ordinary letters and numbers. Symbols can prevent the private match from being created.
Custom Matchmaking Keys are case sensitive for participants. Share the key with its intended upper- and lowercase letters.
Epic specifically recommends hiding the key while streaming to keep unwanted guests from joining the match.
Set the mode and region before you create the key.
A Custom Match host has three dependencies to align before players are invited: a supported Battle Royale mode, the same server region as participants and a correctly formatted Custom Key. The sequence below follows Epic's published host flow.
In the lobby, select the Battle Royale game mode. Epic says Custom Matches cannot be created in other game modes.
Confirm that the host uses the same matchmaking region as the participants. A region mismatch can prevent a match from starting.
Scroll down in the game-mode selection screen until the Custom Key button appears at the bottom right, then select it.
Enter a 4-16 character key without special characters and keep the capitalization you expect participants to type.
Select Accept, press Play and wait while participants enter the same key and queue for the session.
When the intended players are ready, select Start Match. Epic says the host can start the game manually at any time.
Joining is simple only when every setting matches the host.
Participants do not need to guess where the session is. They must use the host's server region, select the same game mode and enter the exact Custom Matchmaking Key before the host begins the match.
Open settings and confirm the same matchmaking region as the host. Epic says a wrong region results in an error and prevents joining.
Use Change to open the game-mode menu and select the same supported Battle Royale mode the host selected.
Choose Custom Matchmaking Key in the mode flow to open the entry field for the host's key.
Enter the received key with matching capitalization. The key is case sensitive and special characters are not allowed.
Select Accept, click Play and wait in the queue. The session begins only when the host starts the match.
Do not wait for the host to launch. Epic says players attempting to join after the match has begun receive an error.
A key is not a guaranteed seat once more than 100 players try it.
Epic sets the maximum Custom Match capacity at 100 players. If more than 100 people enter the key at the same time, Fortnite chooses 100 randomly; it is not a first-come, first-served queue.
A Custom Match can contain no more than 100 participants according to Epic's current support guidance.
If more than 100 players submit the key at once, Fortnite randomly selects 100. Entry order does not create priority.
Epic says that being kicked immediately after joining can mean the host's match has already reached the 100-player maximum.
Solve the matching dependency that failed.
Custom Match errors are usually specific: unsupported mode, missing creator access, incorrect region, an invalid key, a late join or a full 100-player session. Check them in that order instead of rotating settings at random.
The match.custom_key_not_supported.401 error means the chosen mode does not support Custom Matchmaking. Select an eligible Battle Royale mode and retry.
Confirm active creator or developer program membership and completed account creator setup. Hosting is not available to every player.
Host and participant must use the same server region. Correct the region before re-entering the Custom Matchmaking Key.
Check length, special characters and capitalization. The key must be 4-16 characters, has no special characters and is case sensitive.
A player trying to join after the host has started receives an error. Set a ready check before starting instead of launching immediately after sharing the key.
Check whether the match reached the 100-player maximum. A full session can explain an immediate removal after joining.
A Custom Key creates a private Battle Royale session, not an island or ordinary party.
Custom Matchmaking Key, Discover island codes, party privacy and matchmaking region touch different systems. Keeping those user intents separate avoids the common mistake of entering an island code in a Custom Key field or changing account country for a private-match region issue.
