India Post uses a unique post code system called Postal Index Number (PIN). This system was introduced by Sri. Shriram Bhikaji Velankar in the year 1972 to streamline the sorting and sending of mails. PIN code is a 6 digit code that identifies a particular state or region and helps in the swift delivery of posts. India has 9 PIN regions out of which 8 represent geographical regions and the remaining one is for the Army Postal Service. In addition to this, the first 3 of these 6 digits of code represent the sub region and the helps in sorting the district. The remaining 3 digits signify the exact post office where mails are to be delivered.
It is important to understand that these postal codes do not refer to exact address, as there can be hundreds of houses/homes under one PIN code. It simply means that these codes are used to identify a particular area and the relevant post office of it. Every PIN code is designed to locate only one delivery posts office, which is further responsible of delivering posts to sub-offices located in that region. After the post has reached to the concerned sub-office, it is then delivered to the receiver's doorstep through the postman. Note that, a single incorrect digit number in the PIN code can be confusing and the post might not reach the right door.
