What to do if the username you want isn't available on Facebook
If the username that you want isn't available, you'll need to pick a new one that's not taken yet. You can take a look at our guidelines for usernames to help you create a custom username.
Usernames are generally given to the first individual or business who requests the name. A username may be unavailable if it's already claimed, even if the Page or profile it's associated with isn't published yet. You can learn more about policies for usernames in our Terms.
Bear in mind that you must be an administrator to set a username for your Page.
