It was first used in the U.S and was adopted by the Philippine Postal Corporation (Phlpost). ZIP actually stands for “Zone Improvement Plan”.
Most of us don’t even know what a ZIP Code is. Why would they when they don’t need to send letter through the post office anymore, right? Instead of going to a post office to send a letter, we could just send it via e-mail, and as for packages, there are now fast cargo companies that are more reliable. And with the fast changing world most of the youths now don’t even know the Postal code or ZIP code of their own town. Now, people would be aggravated if their text mates would not reply within an hour. People then must be very patient because they would have to wait for a week just for their letter to reach its destination and it would take another week for them to get the reply. Before the invention of cellular phones, writing a letter and sending it via air mail was the best way of communicating to our loved ones.
