The Postal Index Number (PIN), commonly known as the PIN code, is a unique numerical code used by the Indian postal system to efficiently sort and deliver mail across the country. Introduced on August 15, 1972, by the Indian Postal Service, the PIN code system simplifies the process of identifying locations, reducing errors, and speeding up mail delivery.
Structure of a PIN Code
A PIN code in India consists of six digits, each representing specific geographical information:
First Digit: Indicates the region (Northern, Southern, Western, Eastern, or North-Eastern).
Second Digit: Represents the sub-region (states within the region).
Third Digit: Specifies the sorting district within the state.
Last Three Digits: Denote the specific post office within the district.
For example, in the PIN code 110001:
1 represents the Northern region.
10 corresponds to Delhi as the sub-region and sorting district.
001 identifies the Connaught Place post office.

Mail Sorting and Delivery: Ensures accurate and swift mail distribution.
E-commerce and Online Shopping: Helps businesses determine service availability and estimated delivery time.
Banking and Government Services: Required for official documentation, addresses, and financial transactions.
