What is a ZIP Code and how do they work?

ZIP Codes are 5-digit numbers developed by the United States Postal Service to represent individual post offices across the United States. A ZIP Code is just the name of the postal code system for the United States. Like the US, most countries have their own postal code system names. For example, India calls their system ‘Postal Index Numbers’. The Czech Republic calls their system ‘Postal Routing Numbers’. So, when you hear ‘ZIP Code’ think ‘United States’

There are three main parts of the 5-digit ZIP Code—the national area, the region or city, and the delivery area. The United States Postal Service (USPS) has segmented the country into 10 ZIP Code areas. Starting in the northeast, they are numbered 0-9.
