History of Postal Code

During World War II , the United States Postal Service (USPS) suffered from a shortage of skilled workers who left the country to serve in the military. To deliver mail more efficiently, the USPS created a coding system in 1943 to separate delivery areas in the country’s 124 largest cities. The code will appear between the city and the state (for example, Seattle 6, Washington).

By the 1960s, mail volume (and population) had skyrocketed as the vast majority of national mail was no longer personal correspondence but business mail such as bills, magazines, and advertisements. The post office needed a better system to manage the vast amount of material that moved through the mail every day.



Creation of a system of postal codes
USPS has developed large mail processing centers on the outskirts of major metropolitan areas to avoid transportation problems and delays in delivering mail directly to city centers. With the development of processing centers, the US Postal Service introduced ZIP (Zone Improvement Program) codes.

The idea for the zip code system originated with the Philadelphia postal inspector Robert Moon in 1944. Moon believed that a new coding system was needed, believing that the end of mail by train would soon come , and that planes were to be a huge part of the future of the mail instead. Interestingly, it took almost 20 years to convince the USPS of the need for a new code and implement it.

Zip codes was first announced on July 1, 1963, were designed to help better distribute the growing number of mail in the United States. Every address in the United States has been assigned a specific postal code. However, the use of zip codes was optional at the time.

In 1967, the use of zip codes became mandatory for mass mailing, and the public quickly accepted it. To further optimize mail handling, in 1983 the USPS added a four-digit code to the end of postal codes, ZIP + 4, to break down postal codes into smaller geographic regions based on shipping routes.
