when did the postal service start using a 5 digit zip code?

Answer 1

The postal service implemented postal zones for large cities in 1943. These codes had 1-2 digits. By the early 1960s a more general system was needed, and on July 1, 1963, non-mandatory ZIP codes were announced for the whole country. Robert Moon, an employee of the post office, is considered the father of the ZIP code. He submitted his proposal in 1944 while working as a postal inspector.

The post office only gives credit to Moon for the first three digits of the ZIP code, which describe the region of the country. In most cases, the last two digits coincide with the older postal zone number

In 1967, these were made mandatory for second- and third-class bulk mailers, and the system was soon adopted generally. The United States Post Office used a cartoon character, Mr. ZIP, to promote use of the ZIP code. He was often depicted with a legend such as "USE ZIP CODES" in the selvage of panes of stamps or on labels contained in, or the covers of, booklet panes of stamps. Curiously, the only time the Postal Service issued a stamp promoting the ZIP code, in 1974, Mr. ZIP was not depicted.

In 1983, the U.S. Postal Service began using an expanded ZIP-code system called "ZIP+4", often called "plus-four codes" or "add-on codes."
