BF4 China Rising code not working

Please verify on your receipt that bought a new and not a used copy of BF4 since often people think they're buying a new copy at a store when it's a pre-owned copy. If it was used the code was already redeemed by the original purchaser and you will need to purchase China Rising if you wish to play it.

If you purchased a new copy of BF4 and the code is coming up as already redeemed you must speak with a game advisor who can audit the code to ensure that it is indeed a new un-redeemed code and if so apply it to your account. You can reach a game advisor here:

1 Click on the following link: https://help.ea.com/contact-us
2 Make sure you are logged in (top right corner)
3 Click on the blue button "Contact a Game Advisor"
4 Enter the name of your game or product (or "Origin" for account-related issues) and click "Find Solutions"
5 Select the type of issue and the platform you play on, and click on "Find Solutions".
6 Click on the blue button "I still need help" if the FAQ articles do not apply to your situation.
7 Select a contact option. Note that you may get different contact options depending on your country.

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 (call back feature available to North America only).
