There are a handful of games out there that require you have your “Steam ID” number and Steam doesn’t make it really that easy to find. So I thought I would list the steps here.
Step 1:
Open your Steam console from your desktop and click on “View” from the top menu.
Step 2:
Click on settings and then click on Interface
Step 3:
From the interface menu: Check mark “Display Steam URL address bar when available” and hit “Ok.”
Step 4:
Once, you hit ok, the menu will close out. Go to your profile. Your ID number will appear at the very end of web link.
