on 15th August-2022. On August 15, 1972, Postal Identification Number, better knows as the PIN-Code system, was introduced in India. The service also called area codes or zip codes and used for sending letters, couriers and other postal items across the country, has turned 50.
The PIN code system in India was introduced by Shriram Bhikaji Velankar, who was additional secretary in the Union Ministry of Communications and was a senior member of the Posts and Telegraph Board, at the time. The need for a PIN code was felt because there was duplication of names in several places across India. The diversity of languages was also another problem as people used to write addresses in scripts, which made it very difficult to trace addresses. A code system helped postmen deliver the address to the right person.
