@iamairhair , I am guessing that you redeemed these codes sometime ago. Sims 3 should be registered on Origin already and all you need to do is to simply download and install the game and any additional DLC you registered. If games do not show up as available for download, you should be able to redeem those on Origin.
For Sims 2, I'm afraid if you didn't register the game on Origin prior to October 2018, you will not be able to get the game in your Origin Library and Customer Support no longer has the option to add the game either. It may show up in your Library and be available to download and install though. You'd need to check.
I redeemed the Sims 3 code without Origin in the last quarter of 2020, and when I try to redeem it WITH Origin now, it says the code has already been redeemed. Do I email Customer Support and ask them to add the game?
@iamairhair , Yes, you will need to contact Customer Support.
