What is PIN Code

Postal Index Number (PIN or PIN Code) is a 6 digit code of Post Office numbering used by India Post. The PIN was introduced on August 15, 1972. There are 9 PIN regions in the country. The first 8 are geographical regions and the digit 9 is reserved for the Army Postal Service.

This gives relevant information like Circle Name, Region Name, Division Name, Office Name, Pincode, Office Type, Delivery, District, State Name. The PIN Code is made up of four parts:

  • The first digit indicates one of the regions.
  • The first 2 digits together indicate the sub region or one of the postal circles.
  • The first 3 digits together indicate a sorting or revenue district.
  • The last 3 digits refer to the delivery Post Office.

An example of a Postal Index Number 456001, from Ujjain in Madhya Pradesh. 4 indicates the West postal zone, 5 indicates a postal sub-zone in Madhya Pradesh, 6 indicates the Ujjain sorting district, 0 indicates the Ujjain core area service route, 01 indicates the Ujjain Head Office as the delivery office.

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.
