So you got a matchmaking key on your Nintendo Switch. Nice! That usually means someone invited you to join a private game. Or maybe you created a key and want others to join you. Either way, it is easier than it sounds. Let’s break it down in a simple and fun way.
TLDR: A matchmaking key lets you join a private online game on Nintendo Switch. You usually enter it inside the game’s online or multiplayer menu. Make sure you have Nintendo Switch Online if the game requires it. Enter the code correctly, confirm, and you are in!
Now let’s go step by step.
What Is a Matchmaking Key?
A matchmaking key is like a secret password.
It connects you to a specific game session. Not a random one. Not a public one. A private one.
Different games call it different things:
- Matchmaking Key
- Room Code
- Lobby ID
- Dodo Code (Animal Crossing)
- Link Code (Pokémon)
But they all work in a similar way.
What You Need Before Joining
Before you try entering the key, make sure you have the basics ready.
- Your Nintendo Switch
- The game that uses the matchmaking key
- A stable internet connection
- Nintendo Switch Online membership (for most online games)
If your game has free online play, you may not need the membership. But most popular games do.
You can check your membership by going to:
- Home Screen
- Nintendo Switch Online icon (bottom left)
If it says active, you are good to go.

Almost every game has an Online or Multiplayer option in the main menu.

You’re searching for something like:

Select it.
Step 4: Enter the Matchmaking Key
You will see a text box.
Type the code exactly as given.

One small mistake can block you.

If the code works, you will connect to the session.

What If the Code Does Not Work?
Don’t panic. It happens.

Try asking the host to send a fresh code.

Usually from a friend.
Here are common ways people share keys:
