Understanding India Postal Index Number (PIN Code) System

A Postal Index Number (PIN Code) is a 6-digit numeric code used by India Post for sorting and delivering mail accurately. The PIN system was introduced on August 15, 1972, to simplify postal operations across urban and rural regions.

  • Digit 1: Represents the specific Postal Region in India (1 of 9 regions).
  • Digit 2: Represents the sub-region or state circle.
  • Digit 3: Represents the sorting district.
  • Digits 4-6: Indicates the specific Post Office location responsible for final delivery.
