ZIP Code Day is celebrated annually on July 1. It’s a day dedicated to recognizing the importance of ZIP codes and how they facilitate efficient mail and package delivery across the United States¹. Let’s delve into the fascinating history and significance of ZIP codes:
- Origin of ZIP Codes:
- The concept of ZIP codes originated in the late 1960s when the Post Office Department introduced them. The goal was to enhance mail travel efficiency.
- The first cities to be divided into designated ZIP code sectors were London and Liverpool in England. However, after World War I, this system spread globally, known by various names such as postal codes or pin codes.
- The United States adopted ZIP codes in the early 1960s. The idea was to help mail move more efficiently by adding ZIP codes to the final address. Over time, ZIP codes have evolved beyond their initial purpose and are now used for collecting geographical statistics, credit card authorization, internet routing, identifying legislative districts, insurance-related tasks, and more.
- The term ‘ZIP code’ was first registered by the United States Postal Service. Since 1967, the post office has made it mandatory to use ZIP codes for bulk mailers.
- ZIP codes have even become popular in pop culture. The most famous ZIP code is 90210 in Beverly Hills, thanks to the iconic ’90s TV show of the same name.
- ZIP Code Day Timeline:
- 1943: The United States Post Office Department (USPOD) implements postal zones for several large cities.
- 1944: Robert Moon, a postal inspector, submits his proposal for a ZIP code system.
- 1963: The ZIP code’s 5-digit sequence goes national in the United States.
- 1983: The Zip+4 system is introduced, which includes the five digits of the ZIP code followed by a hyphen and four additional digits to designate a more specific location.
