What Is the Postal Code of United States?
The postal code of the United States is a system used to organize and categorize mail delivery across the country. Also known as ZIP codes, these numerical codes are used by the United States Postal Service (USPS) to efficiently route and deliver mail to specific locations. Understanding the postal code system is essential for accurate and timely mail delivery.
The postal code system in the United States was introduced in 1963 by the USPS to improve mail delivery efficiency. ZIP stands for “Zone Improvement Plan,” and it was developed to simplify the sorting and processing of mail. The postal code consists of a five-digit number, and additional four-digit codes, known as ZIP+4 codes, were later introduced to provide even more precise location information.
The first digit of the five-digit ZIP code represents a specific geographical region of the United States. The subsequent two digits narrow down the location further by identifying a specific central post office or mail processing center. The last two digits represent a specific delivery area within that region or center. ZIP+4 codes provide even more accuracy by pinpointing a specific street or building within the delivery area.
