Postal infrastructure refers to the systems and facilities that enable the delivery of mail and packages. This includes post offices, sorting centers, and transportation networks such as trucks and airplanes. These components work together to ensure that letters and parcels are efficiently processed and delivered to their intended destinations. In addition to physical locations, postal infrastructure also involves technology and logistics. Automated sorting machines help speed up the processing of mail, while tracking systems allow senders and recipients to monitor their shipments. Overall, a well-functioning postal infrastructure is essential for effective communication and commerce in society.
