Bro, they have your proper record. We had a lahore number car since 2005 which we bought zero meter. And now, he also registered our new car from lahore. We are from faisalabad. I don't know much about NOC but yes, they keep record your of car
Record is maintained at that time when you pay at ur registered post office. If u pay in City B with some jack, jugar, tout or kind of sifarish or bribe record will be not updated until n unless you get NOC from your last Post office.
