What is a PIN Code? (Postal Index Number)
A Postal Index Number or PIN or pin code is a code in the post office numbering or post code system used by India Post, the Indian postal administration. The code is six digits long.
The PIN Code system was introduced on 15 August 1972. The system was introduced to simplify the manual sorting and delivery of mail by eliminating confusion over incorrect addresses, similar place names, and different languages used by the public.

Let us check the above example Pin code. The pin code 456001 is from Ujjain, Madhya Pradesh. The first three digits of the PIN represent a specific geographical region called a sorting district that is headquartered at the main post office of the largest city and is known as the sorting office. So in this case it’s in Ujjain. A state may have one or more sorting districts depending on the volumes of mail handled.
The fourth digit represents the route on which a Delivery office is located in the sorting district. This is 0 for offices in the core area of the sorting district.
The last two digits represent the delivery office within the sorting district starting from 01 which would be the General Post Office or Head Office. The numbering of the delivery office is done chronologically with higher numbers assigned to newer delivery offices. If the volume of mail handled at a delivery office is too large, a new delivery office is created and the next available PIN is assigned. Thus two delivery offices situated next to each other will only have the first four digits in common.
