Key Features of Postal Codes:

• Varied Formats: The structure of a postal code can differ greatly from one country to another. For example, Canada uses an alphanumeric system (e.g., M5H 2L3), while France uses a five-digit numeric system.
• Geographic Specificity: Postal codes often delineate specific geographic areas, ranging from entire cities to individual blocks or even buildings.
• Sorting Efficiency: By providing a precise location identifier, postal codes allow postal services to automate mail sorting and delivery processes.

What is a ZIP Code?

ZIP code, an acronym for Zone Improvement Plan, is a postal code system used by the United States Postal Service (USPS). Introduced in 1963, ZIP codes were designed to expedite mail delivery across the United States. The basic ZIP code is composed of five digits, with an additional four digits (ZIP+4) added in 1983 to further refine delivery routes.

Key Features of ZIP Codes:

• Numeric System: ZIP codes are exclusively numeric, consisting of five or nine digits.
• Hierarchical Structure: The first digit of a ZIP code represents a broad geographic area, while subsequent digits narrow down the location to specific regions, cities, and even delivery blocks.
• ZIP+4: The four-digit extension of the ZIP code identifies a specific delivery route or postal box, enhancing delivery accuracy.
