Can you check if an EA Online Pass has been activated?

I'm planning to sell or trade in my copy of Dead Space 2 when I am done with it. I haven't used the online code, which should work in favor of the resale value... BUT, is there a way to verify if the code has been used or not? If I take it to the store, do they simply have to take my word for it, or can they check?

They most likely can't check it, so you should sell it to a person, not a store.
