postal networks
Letter routing infrastructure
Postal networks are systems for collecting, transporting, and delivering mail across geographic areas.
The term encompasses both the physical infrastructure—post offices, sorting facilities, delivery routes—and the organizational structure that coordinates them.
National postal services form networks linking cities and towns; international mail relies on interconnected networks spanning borders.
The postal network extends to even the most remote villages.
