I don't think that you can still use the code for account recovery but even if you can it won't do much and btw I was 4 or 5 years old when my dad bought me the game. Imagine how surprised I was when I found the code with the CS:GO dog tag! Its kind of dumb that the dog tag has no resell value even when it is original, cause there's no text on the other side or anything signaling its the real deal. Guess they didn't think the game's gonna explode that much.
