Facebook Providing Usernames

From Saturday, June 13th, you will be getting a unique usernames just like other sites such as LinkedIn. This will help others to find you easily on Google or other search engines. Earlier the profile is identified by the unique number that it has at the end of the url of the pages you visit. The URL was just a randomly assigned number like “id=592952074.” That soon will change. When your friends, family members or co-workers visit your profile or Pages on Facebook, they will be able to enter your username as part of the URL in their browser. This way people will have an easy-to-remember way to find you.

Facebook usernames will be available in basic text forms, and you can only choose a single username for your profile and for each of the Pages that you administer. Your username must be at least five characters in length and only include alphanumeric characters (A-Z, 0-9), or a period or full stop ("."). While usernames are currently available only for Romanized text, we’re looking at how we might support non-Romanized characters in the future.
Think carefully about the username you choose. Once it’s been selected, you won’t be able to change or transfer it. If you signed up for a Facebook Page after May 31 or a user profile after today at 3 p.m. EDT, you may not be able to sign up for a username immediately because of steps we’ve taken to prevent abuse or “squatting” on names.
