Line 201: {{further\|ZIP Code}} In the United States, the basic [[ZIP Code]] is composed of five ~~numbers~~digits. The first three ~~numbers~~digits identify a specific [[sectional center facility]]—or central sorting facility—that serves a geographic region (typically a large part of a state). The next two ~~numbers~~digits identify a specific post office either serving an area of a city (if in an urban area or large suburban area) or an entire village, town, or small city and its surrounding area (if in a small suburban or rural area). There is an extended format of the ZIP Code known as the [[ZIP+4]], which contains the basic five-digit ZIP Code, followed by a hyphen and four additional digits. These digits identify a specific delivery route, such as one side of a building, a group of apartments, or several floors of a large office building. Although using the ZIP+4 offers higher accuracy, addressing redundancy, and sorting efficiency within the [[USPS]], it is optional and not widely used by the general public. It is primarily only used by business mailers.
