A geographical index displays postal code boundaries within a specific borough of New York City. This visual tool delineates areas designated by numerical identifiers for mail delivery and statistical tracking purposes within the aforementioned region. As an example, specific areas in the northern part of the borough are differentiated from those in the southern region, each represented by a unique code and defined boundary lines on the referenced index.
Such a resource offers several advantages. It facilitates efficient mail sorting and delivery by providing a clear visual representation of postal divisions. Furthermore, it is valuable for demographic analysis, urban planning, and market research, as postal codes often correlate with socioeconomic data. Historically, the development of these indices reflected the increasing complexity of urban areas and the need for improved logistical organization.
