How to Add Admins to Your American Truck Simulator Server

Published June 9, 2026 · By Host Havoc Technical Support Team

Admins on your American Truck Simulator server are defined as moderators in server_config.sii. Each moderator is identified by their Steam64 ID.

This guide also applies to Euro Truck Simulator 2 servers.

Find a player's Steam64 ID

Use a lookup tool such as steamid.io to find the Steam64 ID of each player you want to add.

Add moderators to the server

  1. Log in to the Game Control Panel and navigate to your server.
  2. Click Stop to stop the server.
  3. Click Configuration Files, then find server_config.sii and click Config Editor.
  4. Scroll down to the Moderator List section.
  5. Set moderator_list to the total number of admins you want to add:
    moderator_list: 3

    moderator_list[1]: 76985544003244
    moderator_list[2]: 79981032165441
