Why did I Lose my Sims 3 serial code?

I lost my Sims 3 Serial code. [SOLVED] I wanted to install my Sims 3 game again, which is on CD, because I bought Sims 3 pets on Origin. Although, I do have the Sims 3 disc and case, but I lost my booklet that contained the serial code. And I didn’t register it on the Sims 3 website, so I can’t get it from here.
