Register sims 3 bought on Steam on the Sims Store

@Panda14616  Yes, you need an Origin account to purchase points now, as the Sims 3 store no longer has the ability to handle cash transactions.  But it's easy enough to link your store account to Origin, in which case your registered content would be added to your Origin account.  (In fact, Origin may already recognize your account credentials without your having to re-register, but I'm not sure.)

You can buy EA cash cards and add them to your Origin account without needing to provide any credit card information, and then you can use the money to buy points, or worlds that require cash instead of points.  I've seen the cards on sale at Best Buy; google says they're also offered by Walmart and Target, among other places.

I did that and it didn't work

@kayla20618  What exactly are you trying to do?

How did you register it to sims3.com?

@talksic3  If you already have an account on the site (www.thesims3.com ), sign in, scroll down to the bottom of the page, click "Register a game," and add the product key.  If you don't have an account, you'll be asked to input a key when you're creating one.

Since this thread is a few years old now, I'll lock it here.  If you still need help, please create a new thread describing the issue, as well as where you bought the code.
