A postal code is a numeric (and sometimes alphanumeric) code used by a postal service to facilitate the sorting and delivery of mail. This system assigns specific geographic regions to unique identifiers, allowing for efficient routing. For example, a five-digit number identifies a particular delivery area within a city or region.
Utilizing these codes ensures mail reaches its destination promptly and accurately. This is vital for businesses, residents, and governmental organizations. The structured system streamlines logistics, enabling efficient distribution of resources and communication across designated locations. The introduction of this system represented a significant advancement in postal efficiency.
