Did you create a custom URL for your Facebook page but wish you had chosen differently? Previously, Facebook page admins were stuck with the URL they chose when setting up the page. Facebook announced today that page admins now have the ability to change the URL for their page, but there is a catch - you can only change it once.
To make the change, go to the top of your Page by the Admin Panel and click Edit Page > Update Info > Basic Information > Change Username. Since this is your one shot to make a change, make sure you choose a URL that is easy to remember and best reflects your business name so customers can easily find you on Facebook.
NOTE: Usernames are single-use, so you won't be able to create a new account with a previously-used name. Facebook doesn't consider case or punctuation, so CompanyName is the same as company-name.
Remember, once you have changed your username/URL, your old one won't work—so keep this in mind if you've already distributed any materials with your Facebook address pre-printed. Also make sure you update any Facebook links on your website.
