Post (Mail)

The post is a system for sending letters and packages from one person to another. Most countries run their own postal service. In the United States, it is called the United States Postal Service, or USPS. A piece of mail travels through a chain of workers and machines, often across thousands of miles, to reach the right doorstep. The post is one of the oldest forms of long-distance communication still used today.

People have sent messages over long distances for thousands of years. Ancient Persia, around 550 BCE, had a network of riders who carried royal messages between cities. The Roman Empire built a similar system called the cursus publicus. China, Egypt, and the Aztec Empire all had their own message runners. These early systems were mostly for kings and governments, not regular people.

Public mail for everyone is a newer idea. In 1840, Britain started selling the first sticky postage stamp, the Penny Black. Now anyone could pay a small, fixed price to send a letter anywhere in the country. Other countries copied the idea quickly. Mail became cheap, fast, and open to all.

In the United States, Benjamin Franklin set up the colonial postal system in 1775. He became the first Postmaster General. Later, the post helped tie the growing country together. Mail traveled by horse, stagecoach, steamboat, and train. The Pony Express, a famous horseback mail service, carried letters across nearly 2,000 miles between Missouri and California in about 10 days.

How does a letter get to your house today? You drop it in a blue collection box. A postal worker picks it up and brings it to a sorting center. Giant machines read the address and sort thousands of letters per minute. Trucks and planes carry the mail toward its destination. Another sorting center hands it to a local carrier, who walks or drives a route and slides it into your mailbox. The USPS delivers about 116 billion pieces of mail each year. That is more than 300 million pieces every day.

Email and text messages have changed how people use the post. Far fewer letters get sent now than 30 years ago. But package delivery has exploded because of online shopping. Today most mail is bills, ads, and boxes from stores. Even so, a handwritten letter still feels different from a text. Someone sat down, picked the words, found a stamp, and trusted the system to carry it across the country to you.
