A postal system is a network that allows people to send and receive letters and packages. It includes various services like mail delivery, post offices, and postal workers who ensure that items are transported safely and efficiently. Each country has its own postal system, which may offer different services, such as express delivery or international shipping. The history of postal systems dates back thousands of years, with ancient civilizations using messengers to deliver messages. Today, modern postal systems use technology to track packages and improve delivery times. They play a crucial role in communication and commerce, connecting people across the globe.
