First, you need to create an Origin account., if you don't have such account 
Download Origin from here.
http://origin.com/download
Create your account using your e-mail address. Write down this mail address because if you lost it you will be lost the game also.
Then log in on your account and go to the "My games library"
On the top right you will find options: "add game" Enter the game code there.

I don't work for EA
