What is Postal Code in USA?
Postal codes or ZIP codes, are a series of numbers and letters that identify a particular postal address in a country. They allow mail to be sorted automatically and delivered quickly and accurately. The United States, being one of the top funding members of the Universal Postal Union (UPU), is at the forefront of developing new postal code systems to streamline global mail exchange and delivery processes.
In the United States, a ZIP code is a five-digit number that divides the country into regions or delivery areas. A ZIP+4 code, introduced in 1983, adds four more digits to the basic five-digit code to identify a geographic segment within the delivery area.
While it may seem like a series of random numbers thrown together, each digit in the ZIP code conveys a different meaning. For example, the first digit of a ZIP code denotes which state the mail is to be sent to. The second digit indicates the region, while the third identifies the associated post office or delivery area for that region. The fourth and fifth digits identify the specific street address or postal box for that region.
