The Department of Posts (DoP), trading as India Post, is a government-operated postal system in India, which is a subsidiary of the Ministry of Communications. Generally called "the post office" in India, it is the most widely distributed postal system in the world.
Founded in 1854 by Lord Dalhousie who laid the foundation for the modern Indian postal service. Dalhousie introduced uniform postage rates (universal service) & passed the India Post office act 1854 which significantly improved upon Lord William Bentinck's 1837 act which had introduced Post offices in India. It created the position Director General of post for the whole country.
It is involved in delivering mail (post), remitting money by money orders, accepting deposits under Small Savings Schemes, providing life insurance cover under Postal Life Insurance (PLI) and Rural Postal Life Insurance (RPLI) and providing retail services like bill collection, sale of forms, etc.
The DoP also acts as an agent for Government of India in discharging other services for citizens such as old age pension payments and Mahatma Gandhi National Rural Employment Guarantee Scheme (MGNREGS) wage disbursement. With 155,015 post offices, India Post has the most widely distributed postal network in the world.
