postal systems
Letter distribution infrastructure
Postal systems are organized networks for collecting, transporting, and delivering mail and packages.
Most countries operate a national postal service—the USPS in America, Royal Mail in Britain.
The term encompasses the infrastructure of post offices, sorting facilities, delivery routes, and carriers that move correspondence from sender to recipient.
