How to Find a Person From Their Facebook ID

Facebook assigns each new user a unique identification number. You use this identification number in the Facebook URL to find a user. The user's profile displays, and you can submit a Facebook friend request or read the user's Wall posts using the identification number in the URL's "ID" querystring.
