postal service

A postal service is a system that facilitates the collection, transportation, and delivery of letters, packages, and other mailed items. It operates through a network of post offices, sorting centers, and transportation methods such as trucks, planes, and trains. The service ensures that mail reaches recipients efficiently and securely, often offering additional options like tracked delivery or express services. Postal services are essential for personal communication, business transactions, and the distribution of goods, serving as a reliable infrastructure that connects individuals and organizations across local, national, and international borders.
