What Exactly is a ZIP Code?

ZIP codes, which stand for Zone Improvement Plan codes, were introduced by the United States Postal Service (USPS) in 1963. They are essentially a system of postal codes used to streamline mail delivery. The initial ZIP codes were five digits long, but the USPS later added an extra four digits (ZIP+4) to provide even more specific routing.

Understanding ZIP codes is fundamental to ensuring your mail reaches its destination promptly and efficiently. The five-digit code designates a specific geographic area, while the extra four digits can pinpoint a street address, a group of apartments, or a PO box. The use of ZIP codes has greatly improved the sorting and delivery process, reducing errors and increasing speed.

The Structure of a ZIP Code

First Digit: Represents a group of US states or territories.
Second and Third Digits: Indicate a region or a sectional center facility (SCF) within that group.
Fourth and Fifth Digits: Identify the post office or delivery area.

Knowing the structure of ZIP codes can help you better understand how the USPS organizes and delivers mail across the country.
