A PIN code (Postal Index Number) is a 6-digit code used by India Post to identify every post office in India. Introduced on 15 August 1972, it helps sort and deliver mail accurately across all states and union territories.
An Indian PIN code has exactly 6 digits. The first digit represents the postal zone (1–9), the second the sub-zone, the third the sorting district, and the last three digits identify the specific post office.
