Decoding the Pincode - Logic behind the Pincode and its significance


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:

First Digit

States Covered
1

2
Northern

3
Western

Eastern

Army Postal Service

In our Example (600017), First digit 6 represent Southern Region.

     2. SECOND DIGIT(First Two Digits) : State / Circle

The first two digits together used to represent the State / Postal Circle.  We have 28 such categories which is given below:

Conclusion:

Until we know the importance of something, we will not take those things seriously. Same thing applies to the pin code as well. I didn’t know about the importance and significance of these pincodes and happened to see a poster explaining the importance of pincode,  in velachery post office while sending a speed post there. Mentioning the correct pin code makes the sorting officials task more easier and would lead to a speedy delivery of the posts. Same is applicable in case of Couriers as well.

Thanks for your patience in reading my post, hope it is helpful in some way or other. Do drop in your suggestions and feedback to innovativedeepak87@gmail.com . Meet you all in the next post very soon.
