Let us try and understand the meaning and structure of a 6-digit PIN with an example. The example used here is PIN 110001. All the six digits in a PIN have a meaning.
- The first digit indicates a postal zone or region. 1 in our example indicates Northern region.
- The first 2 digits denote the postal circle or sub region. 11 denotes Delhi.
- The third digit 0 stands for the sorting district i.e. Central Delhi
- The last 3 digits stand for the specific post office. In this example 001 means Connaught Place.
- Hence 110001 get decoded as Connaught Place Post Office in Central Delhi sorting district of Northern region.
As per this system, the 6 digit Pincode ‘110001’ for example, gets decoded as Connaught Place Post Office in the Central Delhi sorting district of Northern region.( How to decode the 6 digit code structure is explained subsequently)
Importance of Pincode
- Each PIN code maps one single, unique delivery post office in the India Post network. This uniquely coded delivery post office receives all the mail to be delivered to it and all the lower offices within its jurisdiction, with all of them sharing the same code.
- Post received by a delivery office (General Post Office, Head Office or Sub Office) gets sorted there basis the PIN given in the address and it is then routed to other delivery offices based on their unique PIN codes or it is sent for sub distribution and final delivery to lower offices with their own jurisdiction.
- This is why mentioning PIN code has became an important part of any address in India for India Post and for courier companies
- The PIN code system increases the efficiency of the postal distribution system by ensuring speedy sorting and delivery.
- It reduces confusion and errors created by similar place names, incomplete or incorrect addresses and the myriad of languages and scripts prevalent in India.
- PIN has made life easier for the post man when it was introduced by India Post in 1972.
