This system was introduced by Shriram Bhikaji Velankar in 1972. The information of Pin code is necessary to the point that is the reason pin code week is commended. The full name of the PIN is Postal Index Number.
The pin code week is commended each year from 15th of January to the 21st of January to disperse the message about pin code significance. Each document has a little rectangular box which again has six allotments to top off the pin code number of the specific place. This box is large disregarded by the general population and left unfilled. This little box speaks to a guiding wheel of the letter for the postal office.
