How Can I Get a Unique URL and Username for My Facebook Page?

To get a unique URL for your Facebook page, you have to create a unique username for it. You cannot create a unique username for your Facebook page until 25 people add your page to their lists of pages they like. Once 25 people like your page, you can visit http://www.facebook.com/username to create your page's username. Once you select your page's username, the unique URL for your page becomes http://www.facebook.com/yourpageusername.
