53106

53106 is a United States ZIP code used by the United States Postal Service to designate a specific geographic area for mail delivery and routing. ZIP codes are five-digit numeric identifiers introduced to improve mail sorting and delivery efficiency. In the ZIP code system, the first digit designates a broad region of the country, the middle digits narrow the routing area, and the final two digits identify a more precise post office or delivery neighborhood. The code 53106 thus represents a particular delivery area within Wisconsin, a state in the Midwest region of the United States.

The U.S. Postal Service assigns and maintains ZIP code boundaries, which can shift over time due to population changes, municipal annexations, or logistical adjustments in postal operations. Addresses within 53106 are served by a designated local post office responsible for mail intake, sorting, and local delivery. In addition to mail processing, ZIP codes are commonly used in data analysis, logistics, marketing, and geographic information systems to approximate location, delineate service areas, and support regional planning.

As a numeric designation, 53106 does not imply political jurisdiction and may intersect multiple municipalities or neighborhoods. Its primary function is to ensure accurate routing and delivery of mail, while also serving as a convenient geographic reference in various non-postal applications.
