Until recently, Facebook required pages and individual users to have at least 25 friends in order to claim a customized address extension. That meant any new users had to accept an ugly URL usually including a long number.
No one can remember URLs like this and they’re too long to put on your marketing materials.
Now you no longer need 25 friends for your profile or page to get an easier-to-remember address.
Go to facebook.com/username to choose custom URLs for your pages.
