1970s Soviet stamp promoting the use of postal codesThe development of postal codes reflects the increasing complexity of postal delivery as populations grew and the became more complex. This happened first in large cities. Postal codes began with postal district numbers (or postal zone numbers) within large cities. Was first subdivided into 10 districts in 1857, and in 1864. By, such postal district or zone numbers existed in various large European cities. They existed in the United States at least as early as the 1920s, possibly implemented at the local post office level only (for example, instances of 'Boston 9, Mass' in 1920 are attested, ) although they were evidently not used throughout all major US cities (implemented -wide) until.By 1930 or earlier the idea of extending postal district or zone numbering plans beyond large cities to cover even small towns and rural locales was in the air.
These developed into postal codes as they are defined today. The name of US postal codes, 'ZIP codes', reflects this evolutionary growth from a zone plan to a zone improvement plan, 'ZIP'. Modern postal codes were first introduced in the in December 1932, but the system was abandoned in 1939.
The next country to introduce postal codes was Germany in 1941, followed by Singapore in 1950, Argentina in 1958, the United States in 1963 and Switzerland in 1964.
