What In The World Is A ZIP Code?

Have you ever had difficulty remembering your ZIP code? Can you still recall the first time you heard about emails, how you rushed straight home from school to log on to your computer, only to find yourself stumped when the registration page required you to enter a valid ZIP code?

So what exactly are these ZIP codes we keep hearing about but never seem to make use of? Why were they invented and for what purpose? In this article, we'll discuss about a little history about the ZIP code, its functions, and how it affects the modern world as we live in it today.

A ZIP code (or Zone Improvement Plan code) is a standardized series of numbers and/or letters used and implemented by the United States Postal Service or USPS. It is usually written along with the postal address for efficiency in mail sorting. Other accepted interchangeable terms include postal code, postcode, or post code.

The first country to identify the need for a ZIP code system was Germany. And so in 1941, the Germans were the first to implement their own national ZIP code system. Roughly 18 years later, the United Kingdom followed suit, and the United States too, four years later.

So if you're a modern-day student who prefers sending emails over the Internet, then you don't really have any real use for ZIP codes. But if you work in a post office, then the ZIP code becomes an indispensable aspect of your daily life simply because it helps you organize the thousands of mails that pass through your hands every single day.

To help people get their ZIP codes right, countries publish a special book called a ZIP code directory. A ZIP code usually covers an extensive listing of ZIP codes but only within a specific country. So the next time you find yourself stuck on an online registration page or you simply want to write someone a letter via the traditional way, you might want to look up the right ZIP codes on a ZIP code dictionary.
