What is Pin (Postal Index Number) ?

While sending a letter or a parcel via the Indian postal system or by courier, do you wonder if it will safely reach its destination? The chances of your letter reaching its intended recipient are increased every time you remember to include the PIN Code of the destination.

India is such a vast country with so many cities, towns and villages that finding the right place or person can be a real challenge for the Indian Postal Service (and for courier services). In order to make the process of delivering letters and parcels more efficient, the Indian Postal service introduced the 6-digit Postal Index Number (PIN) Code on 15 August 1972.

The Indian Postal Service has designated 9 specific PIN regions across the country, out of which 8 are geographical regions and the 9th is reserved for the Indian Army.

What is the Structure of Pin Code (Postal Index Number) ?

Each digit in the 6-digit number has a specific meaning. The first digit designates which is the overall geographical region, and the first 2 digits designate the postal circle or sub-region. The third digit designates the sorting district. Thus, the first 3 digits collectively designate the postal district while the last 3 digits indicate the specific post office within the district.
