Decode PIN Code

An Indian PIN (Postal Index Number) code is a six-digit numeric format where the first digit represents the zone, the second the sub-zone, and the third the sorting district. The last three digits identify the specific delivery post office within that district.  

First digit: Represents the postal zone (e.g., the northern zone starts with '1'). 

Second digit: Indicates the sub-region or postal circle. 

Third digit: Identifies the sorting or revenue district. 

Last three digits: Pinpoint the specific delivery post office within that district. 

For example, the PIN code 110001 for New Delhi works as follows: '1' is the northern zone, '10' is the sub-zone, and '001' specifies the Connaught Place post office.
