Get ready to celebrate the convenience and organization of ZIP codes on July 1, also known as ZIP Code Day! This holiday was created in honor of the first official use of ZIP codes back in 1963. Before that, mail delivery relied on a confusing system of postal zones. But thanks to the introduction of ZIP codes, sending and receiving mail became much more efficient and accurate. So let's take a moment to appreciate this modern invention that has made our lives so much easier – and maybe even send a thank-you card to your local post office!
