Once you get 25 likes on your Facebook page you are eligible for a vanity username. A client just asked me how to do this so I am writing it up for quick reference later.
1. First, log into your Facebook account and go to the fan page in question.
Just below the fan page title and above the status update box there is little link that says “Edit Info” Go ahead and click on that.
2. After you click on “Edit Info” you will be redirected to a page of Basic Information. If you don’t land on the Basic Information page, you should be able to click the link on the left side.
Then click on the words “Create a name for this page? Learn more”
3. Now, you’ll have the opportunity to try out usernames. Chances are your name will be available, but if it isn’t you’ll have to play around with it a bit. Just type names into the field that Facebook Directs you to and if the name is unavailable Facebook will give you the opportunity to try again.
4. Once you do that, Facebook will give you a success message and you are good to go!
