Hi SeanB72,
It'd be best to update the email address on your account, so you can get the verification codes and for general account security. The guide below should give you the steps to try yourself, but if you run into any problems, there's a "Contact Us" button at the bottom to put you in touch with EA Help.

I should mention that you might need to actually speak to EA Help as the self-service option will involve sending a security code. However, you might be able to select a different option for it, such as SMS.
