How to find your Facebook Profile UID
If you need your Facebook profile UID, but you have set a Vanity URL (facebook.com/username), then it’s a little trickier to find if you don’t know where to look. Here’s a really quick way to find it in an instant.
View your Profile
Right-click your profile picture with the right-mouse button
Click “Copy Link Location” with the left-mouse button to copy the full location of your profile image.
Paste Link to Reveal UID
Paste link into your address bar, notepad, or wherever is convenient.
The number at the end of the URL after id= is your Facebook Profile User ID http://www.facebook.com/album.php?profile=1&id=100001328869081
