The alphanumeric string represents a specific physical location. This location is defined by a numerical street address (8403), a street name (Colesville Road), a municipality (Silver Spring), a state (Maryland, abbreviated MD), and a postal code (20910). This combination provides a unique identifier for a property or building within a defined geographical area.
Such an identifier is fundamental for various purposes, including mail delivery, emergency services response, property assessment, business registration, and navigation. Its accuracy and unambiguous nature are crucial for efficient and reliable location-based services. Its historical context lies in the evolution of addressing systems designed to organize and manage urban and suburban environments.
