Decoding the Code.

The Zone Improvement Plan (ZIP) Code was launched in 1963 to better handle increasing volumes of mail. The first number in the code represents a general geographic area of the nation, “0” in the East, moving to “9” in the West. The next two numbers represent regional areas, and the final two identify specific Post Offices. The ZIP+4 Code was introduced in 1983. The extra four numbers allow mail to be sorted to a specific group of streets or to a high-rise building. In 1991, two more numbers were added so that mail could be sorted directly to a residence or business. Today, the use of ZIP Codes extends far beyond the mailing industry, and they are a fundamental component in the nation’s 911 emergency system.
