What is a Zip Code?

ZIP is an acronym for Zone Improvement Plan. The United States Postal Services (USPS) introduced a postal code service known to the common public as Zip Code all the way back in 1963. Just as the acronym suggests, USPS’ intentions for this code was to allow mails and other products to be sent from one location to another efficiently. USPS’ registration for the word “Zip Code” expired in 1997 and is now being used all over the globe for its original purpose. Here is how the little process is done:

How does ZIP code work?

A ZIP Code is five digits long but is never four or six. It is always a fixed number of digits that changes depending on the location. Each location has a fixed ZIP code that never changes as well. The five digits are broken down into:

• First digit represents the broader are, from zero to nine. Zero represents the far Northeast, while nine represents the far West.
• Second and third digits represent the central post office facility of that region. For example, a central post office in Los Angeles will have different second & third digits as compared to a central post office in Springfield.
• The final two digits of the ZIP code are meant to symbolize the small post office or postal zone. This is usually for post offices in a certain city. A post office in the Faircrest Hills of Los Angeles may have different last two-digit codes as compared to Beverly Hills.

Types of ZIP Code:

Here are four types of ZIP codes, depending on where they are used:

• Unique – these are assignment to a single high-volume address, such as a warehouse.
• Post Office Box-only – these are assigned to PO Boxes of a certain facility and are only for use by the post office.
• Military – special ZIP codes used exclusively by the military for mail.
• Standard – the normal ZIP codes that are given to a post office in any region.
