Facebook is now offering ‘Custom Usernames’ to each and every FB user. This means that now your profile will look like:
www.facebook.com/people/custom.username
instead of
www.facebook.com/uid=?749202….
However, there are certain things that you must keep in mind while choosing your username.

These usernames cannot be edited or changed ever, once you signed up for them.
They cannot be transferred in any case.
They will be displayed in your profile link and will stick to it permanently.
Once chosen, it’s final and will be permanent.
Usernames are on first come, first served basis. So you will have to rush before …
