- The 75th Independence Day coincides with another milestone in the country’s history — it was on August 15, 1972, that the Postal Index Number (PIN) was introduced in India.
Why was the PIN code introduced?
- According to the Department of Posts, there were 23,344 post offices, primarily in urban areas, in India at the time of Independence. But the country was growing rapidly and the postal network had to keep pace.
- 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.
How does the PIN code work?
- 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 second number denotes a sub-region,
- The third represents the sorting district.
- The remaining numbers narrow the geography further to the specific post office making the delivery.
The person behind the initiative:
- The person behind the initiative was Shriram Bhikaji Velankar, additional secretary in the Union Ministry of Communications and a senior member of the Posts and Telegraphs Board.
- Velankar was also a Sanskrit poet of eminence who had been conferred the President’s Award for Sanskrit in 1996, three years before he died in Mumbai.
- Velankar was also the chairman of the World Philatelic Exhibition, called Indipex, which was held in New Delhi in 1973 and featured 120 countries.
Some parallel systems followed world over:
- Globally, in the US, the Zone Improvement Plan (ZIP) code was introduced July 1, 1963, under the aegis of the Postal Service Nationwide Improved Mail Service plan to improve the speed of mail delivery.
- Japan created its postal code address system in July 1968.
