The Postal Code of India is defined as a Postal Index Number (PIN) Code, the system used by the Indian postal administration which consists of 6 digit code. The pincode system was introduced in India on 15 August 1972, to make the Indian postal service accessible for people from all regions. Sometimes different places are named similar by the people so that the confusion arises from recognizing the proper postal address. The pin code assists in eliminating confusion over incorrect addresses.
The first digit of Pin code is the identification of the postal region in the country of India, the second one as the postal sub-region / circle; the third one as the postal sorting / revenue district and the last three digits of the zip code is for the delivery post office of India Post. There are nine Postal Index Number (PIN) zones in India. The eight regional postal zones cover all states and union territories of India. The Army Post offices (APO) and Field Post offices (FPO) are coming under the functional postal zone of India Post.
