101 never ask pin everywhere in world ( US include )
Better Credit and Use dumps from same states to get better profit !)
about Zipcode etc ... i cant help too much but i have already seen there some article about store who ask it or no ( try search option forum to find it )
Best bet is Mix Pack. As Varanu Said most stores now do require last 4 digits on plastic to match track2. A lot of larger stores have alot of bins blocked, so best bet is local bins. Local Credit Unions/Banks is a great place to start.
