Basically, PIN stands for Postal Index Number. It is a kind of numerical cipher assigned to post offices. The Indian postal system uses these numbers in the postal code system. It helps to identify the particular location where a letter or shipment will be delivered.

If we stick to the pages of history, we will see that the Pin Code system was started on August 15, 1972 by Shriram Bhikaji Velankar, Additional Secretary of the Union Ministry of Communication. It was introduced to simplify manual sorting and mail delivery by eliminating confusion about wrong addresses, similar place names, and different languages ​​used by the people of the country.

For better management, 9 PIN zones have been created in India. In addition, it contains eight regional zones and a functional zone for the Indian army.

Important fact: Today, there are 1.54 lakh post offices in India.

PIN code understood with precision of six digits. The first digit indicates the region. The second digit shows the sub-region and the third digit indicates the ranking district within the region. The last three digits are assigned to the individual post office. Of the last 3 digits, the last two digits represent the delivery office within the classification district starting from 01, which would be the GPO (General Post Office) or HO (Central Office) or SO (Sub-Office).
