The 76th Independence Day coincides with another milestone in the country’s history.
It was on August 15, 1972, 50 years ago, the Postal Index Number (PIN) was introduced in India.
According to the Department of Posts, there were 23,344 post offices, primarily in urban areas, in India at the time of Independence.
The PIN code was meant to ease the process of mail sorting and delivery in a country where different places, often, have the same or similar names, and letters are written in a wide variety of languages.
The PIN is made up of six digits.
The first number indicates the postal region — Northern, Eastern, Western, Southern; and number 9, which signifies the Army Postal Service.
The person behind the initiative was Shriram Bhikaji Velankar, the then additional secretary in the Union Ministry of Communications.
Globally, in the US, the Zone Improvement Plan (ZIP) code was introduced July 1, 1963.
