History of the U. S. Postal Code System

The United States postal systems began using postal codes as early as the 1940s. They were then two-digit and meant a postal district within the boundaries of one city.

Already in the sixties, the country needed a more specific system. From the very beginning of July 1963, she had already started in test mode. Its creator was Robert Moon, an employee of the departmentUS Postal Service. Interestingly, the world could have known back in 1944 what a ZIP code is, when Robert, being a simple postal inspector, developed this classifier.

ZIP code at that time consisted of five characters, where the first three denoted the sorting center for letters, parcels and parcels, and the last two denoted the number of the post office where they needed to be delivered. Since 1967, the ZIP-indexing system has been declared mandatory throughout the United States. At that time in America, a funny cartoon character Mr. Zip, or Zippy, even appeared on TV screens, urging citizens not to ignore the new system.

In 1983, it had to be complicated and add four more digits specifying the place where correspondence should be delivered, for example, an apartment complex, quarter, branch of a company or division of an organization.

Speaking of what a zip code is, it is impossible not to mention that US government agencies use special numbers. These five and nine digit zip codes cannot be held by any postal user in the county.
