Join a Party with a Code

Enroll in a class with a 6-character join code — from the in-app dialog or a join link — and troubleshoot the common errors.

Demo: partial

Joining a class takes a 6-character join code from your Gamemaster. You can enter it in the app, or open a join link they share — both land you in the same campaign.

Two ways to join

  1. Enter a code in the app

    On Base Camp, switch to the Party Memberships tab on the party card and tap Join with Code. The Join a Party dialog explains: “Enter the 6-character join code provided by your Gamemaster to join the party.” Type the code (it auto-uppercases) into the Join Code field and tap Join Party.

  2. Or open a join link

    If your teacher shares a link like app.rpglms.com/join/ABC123, just open it. You’ll see “Joining with code ABC123…”, and the join runs automatically. If you’re not signed in yet, you’ll sign in first and the join resumes on its own.

  3. Land in the campaign

    On success the app takes you straight to the campaign map for your new class. Next up: Progress through a Campaign.

Why a code might not work

The dialog (or the “Unable to Join” screen, with Retry / Go Home) maps errors to plain messages:

  • Invalid join code — re-check the 6 characters with your teacher.
  • This party has been closed by the Gamemaster.
  • You are already enrolled in this campaign through another party — you can only play a campaign in one party at a time.
  • You must be a member of the organization to join this party — the class is restricted to an organization.
  • This party is full. Please contact your Gamemaster.

Re-joining a class you previously left simply reactivates your membership (your progress is kept).
