Third Digit of PIN Code:
The third digit of a PIN joined with the initial two digits, speaks to a specific geographical region (except in the case of the functional zone for the Army) called a sorting district that is headquartered at the primary post office of the largest city in the region and is known as the sorting office. A state may have at least one or more sorting districts depending on the volume of mail handled.
Fourth Digit of PIN Code:
The fourth digit represents the route on which a delivery office is located in the sorting district.
Fifth and Sixth Digits of PIN Code:
The last two digits represent the delivery office within the sorting district starting from 01 which would be the General Post Office (GPO) or head office (HO). The numbering of the delivery office is done chronologically with higher numbers assigned to newer delivery offices. On the off chance that the volume of mail handled at a delivery office is excessively enormous, a new delivery office is created and the next available PIN is assigned. Thus, two delivery offices situated close to one another will only have the first four digits in common.IN
