Checking if a last name is legit?

[Skanky]

So I scammed some guy's account, and I have his account name/password, first/last name and zip code, but when I search him on white pages he doesn't show up.

How can I check if the last name he gave me is the actual last name on the account?

Thanks in advance.

Check a something like zabbasearch, or knowx - these will give you info without having to pay any money ~~ anyhelp needed send me a PM

Just call Blizzard and they will ask you for both First and Last name. If they can't find your name in the database just hang up.
