Code in the post office numbering or post code system used by India Post

A Postal Index Number (PIN; sometimes redundantly a PIN code)Sometimes incorrectly written as "Pin code", "Pincode", "PINcode", or "pincode". refers to a six digit code in the Indian postal code system used by India Post. On 15 August 2022, the PIN system celebrated its 50th anniversary.

The PIN system was introduced on 15 August 1972 by Shriram Bhikaji Velankar, an additional secretary in the Government of India's Ministry of Communications. The system was introduced to simplify the manual sorting and delivery of mail by eliminating confusion over incorrect addresses, similar place names, and different languages used by the public.

The first digit of a PIN indicates the zone, the second indicates the sub zone, and the third, combined with the first two, indicates the sorting district within that zone. The final three digits are assigned to individual post offices within the sorting district.

The fourth digit represents the route on which a delivery office is located in the sorting district. Thus, two delivery offices situated next to each other will only have the first four digits in common.

The pin code of Dakshin Gangotri in Antarctica is 403001, which is of the pin code of Panaji, Goa.

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 jurisdiction, all of which share the same code. The delivery office can either be a General Post Office (GPO), a head office (HO), or a sub office (SO) which are usually located in urban areas. The post from the delivery office is sorted and routed to other delivery offices for a different PIN or to one of the relevant sub offices or branch offices for the same PIN. Branch offices (BOs) are located in rural areas and have limited postal services.
