Initially, the zip code was only a two-digit number: the first denoted the city, the second denoted the state. But as the need for delivery expanded, so did the concept of the zip code. As of 1963, zip codes' numbers are determined by a few factors: the area, the regional postal facility and the local zone.

So what do the extra numbers mean? These last 4 digits represent specific delivery routes within delivery areas. This extra detail means an even more precise matching to a more granular level. It could represent a handful of houses on one side of a street, or even a single building that receives a high volume of mail.

ZIP Codes are numbered with the first digit representing a certain group of U.S. states, the second and third digits together representing a region in that group (or perhaps a large city) and the fourth and fifth digits representing a group of delivery addresses within that region.

The correct format for a numeric ZIP+4 code is five digits, a hyphen, and four digits. The first five digits represent the 5-digit ZIP Code; the sixth and seventh digits (the first two after the hyphen) identify an area known as a sector; the eighth and ninth digits identify a smaller area known as a segment.

The current postal codes in the United States range from 00001 ? 99950. The lowest and highest of these postal codes are both specific to areas in Alaska; The 00001 code is for the N Dillingham area, and the postal code 99950 is for Ketchikan, AK.

Zoning Improvement Plan (ZIP) codes were implemented in 1963. The five-digit system used the first number to point to a national area, the next two numbers to pinpoint a population centre or large city, and the final two numbers to designate a specific delivery area.

In 1963 the Post Office Department introduced the Zone Improvement Plan (ZIP) Code as a means to allow mail sorting methods to become faster and eventually be automated, but the innovation also created unimagined socio-economic benefits as an organizing and enabling device.
