The history of the Indian postal system is a remarkable journey that reflects the evolution of communication across one of the world’s largest and most diverse countries. From ancient courier systems to one of the largest postal networks in the world, India Post has played a vital role in connecting people, businesses, and governments.
Today, India has over 1.5 lakh post offices spread across urban and rural areas, making it the largest postal network globally. Understanding its history helps appreciate how the modern PIN Code system and delivery structure developed over time.
