From what I know, you need to send whole file to someone in Quetta, he will than go to excise department for verification of documents, which again will be asked with a bit of Quaid-e-Azam as without vehicle verification is impossible. Than an NOC, for what purpose you need that? Inter-provincial transfer or what?
This whole process can take a month or months! depending on Quaid-E-Azam chacha color
