Postal communication refers to the system of sending letters, packages, and other forms of mail from one location to another. This service is typically provided by government agencies, such as the United States Postal Service (USPS) or private companies like FedEx and UPS. Postal communication allows individuals and businesses to share information and goods over long distances. The process involves placing items in an envelope or package, addressing them correctly, and affixing the appropriate postage. Once collected, the mail is transported through various means, including trucks and airplanes, to reach its destination. This method of communication has been essential for personal correspondence, business transactions, and official documents.
