How to Find a Facebook Friend's ID Number

By Carolyn Luck

All Facebook users receive a unique URL, which can be given to friends or posted on external sites on the Web. Made up of a user name and a user identification number, a user's profile URL is visible to anyone with profile-viewing capability. You can easily locate a friend's user ID in a few quick steps.

Step 1

Log in to your Facebook account.

Step 2

Click on the name of a friend, which will bring you to that friend's home page. Choose the "Profile" option.

Step 3

Locate the URL at the top of the profile page. The user ID is the set of digits at the end of the URL following "id=."
