when did the first postal start in india? who was the governer at that time?

Answer 1

The East India Company established post offices in Mumbai, Chennai and Kolkata from 1764-1766, each serving the Bombay, Madras and Calcutta presidencies. During Warren Hastings' governorship, postal service was made available to the general public. A letter would cost 2 annas (one-eighth of a Rupee) for distances upto 100 miles.

Although there was a complex messenger service existing in India for centuries before the British arrived.
