Nowadays, we may not get much traditional letter mail (although it’s a nice way to catch up with friends or family) but we certainly still receive packages and other important mail. And this mail is mostly identified by the use of a postal code or ZIP code. But what is this code and how did it come about?
Postal codes are used by various countries around the world to facilitate the automatic sorting of mail. They consist of a combination of numbers and sometimes letters that represent the range of delivery jurisdictions. Often, these codes are tied to specific geographical areas but the format and implementation differs from country to country.
In the United States, for example, a basic ZIP code is five digits long. The first digit signifies a national area or region, while the second and third digits indicate the association with a city or a delivery area. In addition, the last two digits identify the post office that handles the delivery for this specific zone.
Whether it’s for a business or for personal purposes, an accurate and valid address is essential in today’s world.
