A Brief History of India Post and the Pincode System
India Post traces its origins to Warren Hastings, who established the first post office in Kolkata (then Calcutta) in 1774. Over centuries the network expanded to serve every corner of the subcontinent. The modern Postal Index Number (PIN) system was introduced on 15 August 1972 by Shriram Bhikaji Velankar to streamline mail sorting by replacing name-based sorting with geographic numeric codes. Each of India's nine zones received a dedicated first digit, sub-zones received two-digit identifiers, and individual offices received unique three-digit suffixes — culminating in the 6-digit PIN 573121 that identifies exactly the delivering office for Hakkihalli in Hassan, Karnataka. This system has remained the country's primary postal addressing standard for over five decades.
