Every game on Steam has a different Game ID (also known as App ID). For instance, looking on my own computer, Portal has an ID of 400, and FTL: Faster Than Light is 212680.

How do I find this ID for a specific game on Steam?

I added an answer I came across when searching for this information. The answer will work for most people, however, it does not work in my case as I'm currently in Linux browsing a Windows file system. – IQAndreas Jan 7 '14 at 16:12

Go to the game's store page and check the URL. The last number in the URL is the application ID. All the store URLs are in format, so for Wasteland 2, the URL is, and appID 240760.

Another reliable way is to search for the program on steamdb, which will show you the info for games removed from the store as well. The appid is clearly labelled in the search results.

What is this, an answer that has freehand circles and no upvotes? I shall rectify this injustice! – kotekzot Jan 7 '14 at 16:19
So simple, Que magnifique! Thanks for also editing in the additional information such as a sample game URL and the screenshot. – IQAndreas Jan 7 '14 at 16:21
This won't work for games that have been removed from the store, or games which have never had a store page (which is a surprising number). It also does not work for DLC or packages which do not have their own store page. – BlueRaja - Danny Pflughoeft Jan 9 '14 at 23:01
@BlueRaja-DannyPflughoeft good point, updated the answer – 3ventic Jan 10 '14 at 0:00

Many of the methods above work but I am going to show you an offline version. I am using Windows and uncertain if it works with other systems. If you head into your Steam directory and open SteamApps, and then open common. There you will find a list of games. Open your chosen folder and find "steam_appid". Open it, and it will show the ID in a text document.

many games lack that file steam_appid.txt – Sam Watkins May 2 '14 at 17:07
@SamWatkins Would you have any evidence to support that? – LameBrains May 10 '14 at 11:39
Not sure how to provide evidence to you. I have 395 games installed by steam, of which 88 have steam_appid.txt in the right place, one of those is an empty file. 31 more games have steam_appid.txt in a different location. Only 30% of my games have any steam_appid.txt file anywhere in the installation. Ok here is some evidence you might be able to check. Neither Team Fortress 2 nor DOTA 2 (free games) have any steam_appid.txt (on Linux at least). I can give you one or two windows games without steam_appid.txt if you don't believe me: Jolly Rover, and Cthulhu Saves the World. – Sam Watkins May 11 '14 at 14:30

There is an answer for this in the Steam Support, however, it requires you to be running both Steam and Windows.

Taken from Steam Support: Finding the Application ID for a Steam Game:

This process can also be used for Demos, Media, and other products on Steam:

  1. Login to the Steam account
  2. Go to your Library
  3. Right click the installed game and choose "Create desktop shortcut"
  4. Go to your Desktop and locate the new shortcut
  5. Right-click on the shortcut and select Properties
  6. Look at the target path for the number following steam://rungameid/. This number is the Application ID for the game.

Right click on a game in your library and select Properties. It's in the title of the window that pops up.

I am using a skin but I don't think this works. – LameBrains Jan 9 '14 at 22:30
What language? It could be omitted in a translation of that dialog title. – Ben Jackson Jan 9 '14 at 23:46
I didn't change my language, I just changed my skin to Metro. – LameBrains Jan 12 '14 at 0:10
