Zip Code

Zip codes are employed by US postal services like any other country to send mails to person concerned. Before a tread on to knowing Chicago zip code methods, it is necessary to understand the US zip code procedures.

ZIP stands for Zone Improvement Plan and its inception dates back to 1943 in order to designate a specific coding system for big cities and states. One of the postal workers named Robert Moon forwarded his idea to the authorities in 1941 and gradually plan came into existence by 1943. However, it took little longer to get exercised in full swing.

A general system of zip codes was created by 1960 and the zip codes for entire US were given in 1963. Moon proposed three digits denoting the sectional center of the city as a zip code for the cities. However, present day zip code consists of 5 digit in which 3 digits are of sectional facility center and 2 for the city code.

Zip codes were initially used or sending first class mail and later US postal department started using it for second class and third class mail as well.

In 1983 the Postal Service US department introduced a new format of the zip code in which 5 basic digits were retained and a hyphen and 4 digits are included in the entire zip code. These additional 4 digits designated the geographical region where post is to be mailed. Later these codes were changed to bar codes. Now, if one needs to send post then you have to add 12 digit zip codes.
