The United States Postal Services (USPS) is planning a dramatic overhaul of its services, in an attempt to participate in an increasingly competitive market.
According to a report by the Washington Post, postmaster general John Potter explains that to combat the falling volumes of mail, the post service will become more flexible and implement necessary changes.
This could lead to the end of Saturday deliveries, alongside longer delivery times for letters and packages.
USPS will use a survey, conducted by June Gallop, which showed that 52 per cent of Americans backed five-day deliveries, when presenting its recommendations to Congress.
Mr Potter was positive when discussing the future: "At the end of the day, I'm convinced that if we make the changes that are necessary, we can continue to provide universal service for Americans for decades to come."
"We can turn back from the red to the black, but there are some significant changes we need to make."
It is expected that online services will also be utilized more by USPS.
Currently, mail customers can use online services such as ZIP Code verification to be sure they are posting mail to the correct address.
