The postal code system in the United States consists of five-digit numbers. These numbers are further divided into various segments to identify specific geographic areas, such as cities, towns, and neighborhoods. In some cases, additional digits are added to the ZIP code to provide more precision in locating addresses.
The first digit of a ZIP code represents a specific region of the country. The initial digit ranges from 0 to 9, with 0 primarily used for military addresses.
