Online code does not accept, then I stepped gives error how do I solve this problem

First ensure that you are accruately typing the code and that you purchased a brand new sealed game and not a pre-owned game.  If you purchased a new game and are still getting an error you will need to speak with a game advisor who can verify the code here at EA Customer support:  https://help.ea.com/contact-us

I recommend that you use the telephone option and the “call me” option so you don't have to stay on hold for a long time.
