In India, a PIN code (Postal Index Number) is a six-digit numeric code used by India Post to identify specific geographic regions and simplify mail delivery.
Structure of a PIN Code:
The PIN code system was introduced on August 15, 1972 by Shriram Bhikaji Velankar, then Additional Secretary in the Union Ministry of Communications.
Each PIN code is made up of 6 digits, with the following structure:
- First Digit – Represents the zone (there are 9 postal zones in India, including 1 functional for the Indian Army).
- Second Digit – Represents the sub-zone or a circle/region.
- Third Digit – Combined with the first two digits, it identifies the district within the region.
- Last Three Digits – Identify the specific post office within the district.
Example:
PIN Code: 110001

- 001 → Connaught Place Post Office
