What happens to the mail when it gets close to its destination?
Once mail travels close to its destination, it is unloaded at another postal sorting office. A bar code–reading machine scans the letters again, separating them further for delivery to districts, neighborhoods, and streets. The letters are sent to local post offices, where carriers are given the mail for their delivery areas. Routes may include homes, shops, and office buildings. Carriers who work in farm country, where people live very far apart, may have to travel many miles to deliver the mail each day.
