Decoding the Pin Code
The concept of letter, posts are declining as the day
progresses. Those are the golden days where we write a letter to our grandma staying
the other place and eagerly waiting for their reply. The post cards and the way
we write a big letter within the space provided by the postal authority is
still a big task than posting a tweet in the twitter. The creativity which we
showcase in our 25paise post card can never be replaced with the ones which we
share in FB / WhatsApp / any other medium.
Hand painted customized greetings
for Diwali, Pongal etc in the normal post card brings a lot more joy. We have
to bring back those moments by reviving the post card tradition atleast during
the festivals & occasions .
Ok, coming to the subject matter of this post. While sending a letter, it is customary to write the PIN CODES in the
address field. All that we have learnt is the PIN is the acronym of POSTAL INDEX
NUMBER. But quoting the PIN CODE has a lot more significance that what we think
of.
The PIN CODE consists of 6 digits and there is logic behind
these 6 digits. For all my examples below, I will be using the PIN CODE 600 017
(T.Nagar) since it is easier for us to remember.
The six digits of the pin code can be divided into 4
categories:
1
1. FIRST DIGIT : Region
All the states have been categorized into 8
regions and a separate region for Army Postal Service. Given below the list of
regions:
