To validate the transactions made electronically either in banking, communications or in the payment process, a secret PIN is used.
In the year 1962, the creation of PIN was initiated first in an ATM in Barclays, London.
Further, the PIN is usually used as a passcode/password while making ATM transactions using an ATM card or shopping using a credit card or a mobile SIM card, etc. However, the PIN number is only known to the user and is a secret for both manufacturer/issuer of card. So, it allows users to make transactions securely, as required.
When you go to Bank or a Post office ATM to draw cash to pay your Recurring deposit or Postal life insurance(PLI) or LIC or any other payment, you need to use this secret PIN to complete the transaction.
The security is ensured by blocking the ATM Card if the PIN is wrongly used or fraudulently used. ATM card gets blocked once three wrong attempts are made with the wrong PIN instead of the correct one. This is an additional feature on security for your money in case any fraudulent attempt is made using probability.

The mail emanated from hamlets or Branch post offices or sub-post offices are sorted and also routed to respective RMS. During the night the RMS does the sorting with reference to PIN code majorly to different Sorting Hubs and is bagged and dispatched through Flights/Trains/buses as per the mail arrangements.
Of course, this swift movement with accuracy is possible only through the 6-digit PIN. So, writing PIN code on any letter posted is mandatory and advantageous for you and the postal department in sorting, dispatching, and delivering at the correct destination.
Indeed, Postal Index Number (PIN) is a 6-digit code system implemented by the Department of Posts for the benefit of the public to ensure prompt delivery of postal articles to the destinations without confusion.
There are 9 PIN regions in the country including APS( 9th Region).
The first digit indicates one of the regions.
The opening 2 digits together indicate the Sub Region/a Postal Circle.
The initial 3 digits shows the Sorting District.
The last 3 digits indicate the delivery Post Office intended for.

You write the name of the country it should reach at the end of the postal address just before PIN CODE.
ZIP Code
A ZIP code is a five-digit code implemented by UPPS w.e.f. 1963 and later on it was extended to ZIP+4 code in 1983. Further, 5 digits denote the ZIP-code followed by a hyphen and 4 digits denoting a specific location to understand better the destination.

How to write the correct Address not to miss the delivery?
Many tend to write in a rush when they are supposed to write address in an application for ATM or application for an exam or any other Driving license or basically any letter. But, the result finally will panic you sometimes as you leave out basic things in writing an address.

In addition, the headquarters of a sorting district lies at the largest city in the region often called a sorting office. Based on the mail volume, a state may have one or more sorting districts also.

Fourth Digit: Service route
Similalrly, the fourth digit denotes the route on which a delivery office is positioned in the sorting district. However, in the case of offices lying in the core area of the sorting district, it is represented as zero.
Fifth and sixth Digits: Delivery office
Finally, in the PIN code, the last 2 digits denote the office where delivery of the letters takes place. Meanwhile, for a General Post office(GPO) or a Head Post office(HO), it would be 01. Particularly, the newer offices will be assigned a higher number. Hence, chronological numbering is made for all the delivery offices within the vicinity of the sorting office.
In case a new delivery office is created owing to its handling of a huge volume of mail, it will be assigned with the next PIN code.
As such, there is a also possibility that 2 delivery offices situated next to each other do have only the same first 4 digits in PIN code.
Delivery system
In fact, each PIN is mapped to exactly one delivery post office which receives all the mail to be delivered to one or lower offices within its authority, all of which share the same code. The delivery office can either be a General Post Office (GPO), ahead office (HO), or a sub-office (SO) which are usually located in urban areas. However, Branch Post offices (BOs) do not have a separate PIN code. Hence, they use the PIN code of their respective delivery sub-office under which they are placed. The hamlets under Branch post offices or Sub post offices also carry the same PIN code of that of a delivery SO under whose authority it is placed.
One of the Full forms of PIN Plus:-
Of course, a new concept of PIN plus is derived to augment the delivery efficiency with swiftness. To achieve this, additional 5 digits are also added to the PIN code that denotes the postman beat and delivery point including the provision for the post box even.
Now it is your turn.
In conclusion, whether you understand the importance of the PIN Code now and write the PIN code mandatorily when you write a letter or apply for a job or send any application.
