The ZIP code , an acronym for Zone Improvement Plan was introduced on July 1, by the United States Postal Service to help efficiently deal with the growing number of businesses using direct mailing.

The ZIP code was an extension of the two digit postal code that was already being used in major cities. The main goal was to improve efficiency and accuracy of processing and sorting the mail and dealing with the labor shortage World War II left.

They needed an easy system where they could quickly train their new workers. Read this also: how become a successful Yahoo boy very fast in Nigeria within one year step by step guides. The second 2 numbers represent a central mail processing facility SCF in that region.

The last two digits indicate a more precise location for small post offices or zones in larger cities. Do you want to know all of their list? If you live in one of the states in USA, for example, Idaho, then the zip code of your state is In USA, it is suggested that the mail travels quickly and is delivered more efficiently when a sender uses a Zip code in the postal address.

Meanwhile, if you want your letter to be delivered faster, then adding the Zip code of your state or location to it is your best bet. In the map, 0 is closer to white and 9 is much more vivid. It's easy to follow the gradient across each of the zones even though there are a few exceptions such as the southwest tip of Georgia which uses 39XXX like central Mississippi.

Despite the fact that ZIP codes seem to be geographic in nature, that wasn't their intended purpose. They are intended to group mail to allow the USPS to deliver mail more efficiently. Some ZIP codes will span multiple states in order to make mail routing and delivery more efficient. In most cases, addresses in close proximity to each other are grouped in the same ZIP code which gives the appearance that ZIP codes are defined by a clear geographic boundary.

However, some ZIP codes have nothing to do with geogaphic areas. When ZIP codes appear to be geographically grouped, a clear shape cannot always be drawn around the ZIP code because ZIP codes are only assigned to a point of delivery and not the spaces between delivery points.

In areas without a regular postal route or no mail delivery, ZIP codes may not be defined or have unclear boundaries. The main issue is discussed above: there simply isn't always a clear geographic boundary for a ZIP code. The Census Bureau and many other commercial services will try to interpolate the data to create polygons shapes using straight lines to represent the approximate area covered by a ZIP code, but none of these maps are official or entirely accurate.

They provide a very close approximation of the area covered by a ZIP code. You can easily notice some of the boundary issues when viewing our maps. Very rural areas aren't labeled as belonging to a ZIP code such as much of Nevada and Utah where there are few, if any, addresses to deliver mail. If the address is on the same street as a ZIP code boundary on the map, be sure to search for the full street address to determine the ZIP code instead of relying on the map.

Their purpose is to convey statistical data about regions that are familiar to most citizens. As discussed above, it is difficult to precisely define a geographic area covered by a ZIP code. ZCTAs were developed to account for some of the difficulties in assigning an area to a ZIP code and to precisely define a geographic area.
