A Postal Index Number (PIN) code is a six-digit code used by India Post in the Indian postal code system. Also referred to as Zip codes or area codes, every digit in these codes indicates a specific meaning. Shriram Bhikaji Velankar introduced the PIN code system on 15 August 1972.
The idea behind introducing PIN codes was to make sorting of mail easier as well as accelerate the process of delivering them. These codes have eliminated the confusion caused due to the identical names of regions around the country, the myriad ways in which a place's name may be spelt, and also the usage of numerous languages to write addresses.
The first digit, which ranges from 1 to 9, denotes a postal zone. These nine postal zones are classified into sub-regions which are typically union territories and states. The sub-regions are represented by the second digit. The third digit, when combined with the first two, denotes distinct geographical regions (except for the functional zone for the Army).
This geographical region is called a sorting district, and it is headquartered at the main post office of the region's major city, which is known as the sorting office. The route on which a delivery post office is located in a sorting district is indicated by the third digit. For offices located in the sorting district’s core area, this digit is a 0. The combination of the third and fourth digits focuses on every state's mail-sorting district.
The fifth and sixth digits combined denote a post office under whose jurisdiction the address is located. This numbering is done in a chronological manner beginning with 01, which represents the General Post Office (GPO) or head office (HO) in a region. New delivery offices are denoted by higher numbers. In case a delivery office's mail volume is extremely large, a new delivery office will be formed. This delivery office will be allocated the next available PIN. Thus, any two delivery offices near each other in a given location will have the same first four numbers.
