First 10 People To Sign Up For Facebook.

How To Find Your Facebook Number

Go to facebook.com and log in.

Click on “Profile” or if you’re using the new version, click on your name.

The URL now contains something that ends with id=123456789. The number at the end is your profile ID

Example My Profile ID is

http://www.facebook.com/100000287487742

ID numbers 1-3 were tests that Mark Zuckerberg used to initially test Facebook; the profile pages no longer exist.

The first real Facebook user starts at ID #4. It belongs to — you guessed it — Mark Zuckerberg.
