The History and Evolution of PIN CODEs

The concept of PIN CODEs was introduced in India in 1972 by the Indian Postal Service. Since then, it has become an integral part of the country’s postal system.

A PIN CODE consists of six digits, each representing a particular aspect of the location. The first digit signifies the zone, while the second digit indicates the sub-zone. The third digit represents the sorting district, and the last three digits are assigned to specific post offices within that sorting district.

The Regions and Zones

India is divided into nine postal zones, each denoted by a unique first digit in the PIN CODE. This division helps in the initial sorting of mail and the identification of the general region to which a particular area belongs.

Unique Identification of Post Offices

The last three digits in a PIN CODE are crucial, as they help identify the individual post offices. This level of granularity ensures that the mail reaches the intended recipient with maximum efficiency.

Simplifying Mail Sorting

The logical structure of PIN CODEs simplifies the sorting process significantly, enabling postal services to handle large volumes of mail efficiently.
