A numerical code utilized by the United States Postal Service (USPS) to streamline mail delivery within the city is essential for identifying specific geographic areas. These codes consist of five digits and, in some cases, are extended by four additional digits to further pinpoint locations. For example, a common sequence used in the region begins with the numbers 77.
The proper application of these designated area codes facilitates efficient sorting and routing of mail, packages, and other deliveries. Using the correct identifier ensures that correspondence reaches its intended recipient promptly and accurately. This system plays a vital role in commerce, communication, and logistical operations within the metropolitan area. The implementation of this system has evolved over time to accommodate population growth and expanding delivery networks.
