Robert Moon (postal inspector)

Robert Aurand Moon (April 15, 1917, Williamsport, Pennsylvania, USA – April 11, 2001, Leesburg, Florida, USA), sometimes called "Mr. ZIP", is considered the father of the ZIP Code or Zone Improvement Plan, a mechanism to route mail in the United States.[1]

Biography

In 1944, Moon developed the idea for the "ZIP Code" while working as a postal inspector in Philadelphia, although his system used only the first three digits of what would eventually become a five-digit and later a nine-digit system. The first Directory of Post Offices using five-digit ZIP code numbers would be published in 1963.[1]
