When you setup a page on Facebook the URL will be something like www.facebook.com/your-page-name-1248972121.
This looks pretty ugly if you were to include it on any material like a business card or email signature!
But once you’ve got 25 people liking your page you can apply for your a URL that reflects your name or business name (also called a Facebook vanity URL).
Claiming a friendly username makes your Facebook page easier to find and looks more professional. Try and come up with one that is appropriate for your brand name but easy to remember and read.
Once you claim your username YOU CAN'T CHANGE IT – so choose carefully! *
