A PIN or Postal Index Number also called a PIN code is a six-digit number code used by India Post (the Indian Postal System) to segregate mail and couriers, making delivery more efficient. Each PIN is assigned to a single delivery post office, which receives all mail for distribution to the various offices under its jurisdiction. A postal administration which includes the PIN code system is followed in various nations across the world – it is a universal way of sorting out mail and delivery for many countries and has different names – ZIP codes, postal codes, etc. There are 28 states in India, with at least 720 districts, approximately 6 lakh villages, and over 8200 cities and towns. You can find out the PIN codes for them here on this page.
Every digit in the six-digit number holds a specific meaning. The first digit designates the overall geographical region, with the first two designating the postal circle or sub-region. The third digit represents the sorting district. Therefore, the first three digits represent the postal district as a whole, while the last three digits represent the specific post office within the district.
The Indian Postal Service has designated nine specific PIN regions across the country, eight of which are geographical regions and one is reserved for the Indian Army, called the functional zone. These zones are:
The India Post is spread over 1,55,000 branches across India. It is able to cover around 89 per cent of all rural areas. India is divided into 22 postal circles, each led by a Chief Postmaster General. Furthermore, each of these postal circles is subdivided into regions that are overseen by a Postmaster General, and the regions are further subdivided into divisions, which are further subdivided into subdivisions. In rural areas, the Department of Post serves as a vital link between villages and cities. In addition to mail services, they offer banking services to the rural population, as some of these areas still lack a proper banking facility. The following is the list of postal services provided under India Post: Financial Services: National Savings Certificates (NSC), Kisan Vikas Patra (KSV), and Public Provident Fund (PPF) are some of the services that the post office provides. Further, similar to a banking institution, it allows people to deposit money and provide them schemes related to their monthly income, money order facility, deposit facility in the form of savings bank account, recurring deposit account, and fixed deposit account. Mail Facilities: India Post provides mail services and assists people in sending mail from one location to another. This service includes mail sending, mail registration as security proof, and mail insurance to cover potential risks. Allied Postal Services: These include Direct Post, Speed Post, Media Post, International Money Transfer, Passport facilities, etc.
It was introduced on August 15, 1972, by Shriram Bhikaji, the erstwhile Additional Secretary in the Ministry of Communications.
There are six digits in the PIN code.
There is a total of 19,101 PINs covering 154,725 post offices in India, with the exception of the Army Postal Service, as of 2014.
The primary reason for the implementation of the PIN-code system in India was to assist postal department staff in manually sorting and delivering mail to the correct address, thereby eliminating confusion over similar place names, incorrect addresses, and different languages used by the public.
India has nine (9) Postal zones, eight (8) representing various geographic regions, and the last one is reserved for providing postal services to the armed forces.
