How to Find Out Your Steam ID Numberby James HollowayUpdated September 22, 2017
Your Steam ID number is a unique string of digits that identifies you as a user. However, it isn't visible either on the Steam website or in the Steam client. It's possible to find, but you must use an online tool or the console of a Valve multiplayer game to look it up.
Know What You're Looking For
Depending on what you need it for, you may be asked to find your Steam ID number or your Steam 64 ID. Although based on the same number, they're expressed in very different formats. Finding your Steam 64 ID is simple; you can then use the Steam 64 ID to find your Steam ID number.
Using the Steam Site
On any page of the Steam site, move your cursor over your username displayed at the top of the page. In the drop-down menu, click "Profile." Highlight and copy the URL of your profile in the browser's address bar. The string of numbers at the end of the URL is the Steam 64 ID number; if you're looking for the older Steam ID number, you'll need to convert it.
Using the Steam Client
In the Steam client, click on your username, then select "Profile" from the menu. On your profile page, the URL of your web profile will appear in the upper left hand corner of the page, just below the menu. This is the same URL as that of your profile on the Steam site and includes the same string of digits. Highlight and copy this link.
Getting the ID Number
Visit a Steam ID site such as steamid.co or vacbanned.com (see links in the Resources section). These sites will help you translate your profile URL into a Steam ID number.
If you're playing a Valve multiplayer game like "Team Fortress 2," you can find your Steam ID by typing "status" in the console. Your Steam ID number will appear behind your name.
