US ZIP Code is the ZIP code system used by the UPPS Postal System.
ZIP code means Regional Improvement Plan. The purpose of introducing postal codes is to ensure that all mail can be delivered quickly and efficiently. ZIP codes in the United States are mainly composed of five digits, such as 55416. On the basis of these five numbers, 4 numbers were added later, also known as ZIP +4. For example 55416-4214.
U.S. ZIP codes can be pinpointed to buildings or even occupants on the street through a detailed nine-digit number. This code enables couriers to deliver packages and letters to designated locations in a timely manner.
The first digit of a U.S. ZIP code corresponds to the specific U.S. state group to which it belongs. The second and third numbers correspond to the specific area of the group state it belongs to. The fourth and fifth digits correspond to the group of delivery addresses that belong to that particular area.
