Nine (9) PIN regions are there in India. Out of 9 regions, the first eight (8) regions are geographic regions and the 9th digit is reserved for the armed forces Postal Service.  

The first digit of PIN refers to one of the zones. The second digit of the PIN indicates sub-zone. The third digit of PIN indicates the sorting district. The last three digits indicate the individual Post Office. 

 

Why Need PIN Codes?

The PIN-code system aims to make it easy for the post office staff to manually sort and deliver letters and parcels by avoiding confusion over the similar names of places and incorrect addresses. 

As we all are aware of the fact that India is a big country having 29 states, at least 720 districts containing about six lakh villages, and more than 8200 towns and cities. So remember the entire PIN codes of every location in the country, city, town, or village or to detect a place with its PIN code is not easy. 

So the main reason behind the PIN code system introduction was to provide such a system to the postal department through which they can manually sort and deliver mail (letters, parcels, etc) to the right address and to eliminate the confusion over the similar area names, incorrect addresses and different languages written by people.

The postal index number of India (PIN) is six digits long. PIN codes are generally assigned to geographical areas. But sometimes some institutes and individual addresses like government agencies and big commercial agencies which receive bulk mail are allotted with special codes. An example of such a system is the French CEDEX system.   

Thus PIN code helps the post office to sort mail according to their locations. For a postman, these codes help to deliver the mail to the right people.
