In the sorting district, the fourth digit indicates the route on which a delivery office is situated. For offices in the sorting district's core area, this value is 0.
The last two digits indicate the delivery office within the sorting district starting from 01 which would be the Head Office (HO) and the General Post Office (GPO). The delivery offices are numbered sequentially, with higher numbers allotted to newer delivery offices. A new delivery office is created and the next available PIN is assigned if the volume of mail handled at a delivery office becomes too large. Thus, two delivery offices located next to two each other will have the first four common digits.
