Postal services have come a long way since the days you posted a letter and
prayed it reached.
The Indian Postal Service is owned and managed by the government. It is a
pretty efficient system and provides a wide range of services. Key among them
include financial services (banking, money transfers, issuing life insurance
policies, distributing mutual funds and securities, electronic clearance services
etc) speed posts and a host of other online services.
