1. What is a Zip Code?

A zip code is a postal code used by the United States Postal Service (USPS) to streamline mail delivery. The term "ZIP" stands for Zone Improvement Plan. Introduced in 1963, zip codes have evolved from a system of just a few digits to a more complex system to improve mail sorting accuracy and efficiency. Zip codes help the USPS sort and deliver mail more quickly and accurately by identifying specific geographic areas.

1.1. Structure of a Zip Code

A standard zip code is a five-digit number. The first digit represents a group of states, the second and third digits together indicate a region or a sectional center facility (SCF), and the last two digits represent a specific post office or delivery area. For example, 068xx zip codes are in the Southwestern region of Connecticut.

1.2. Zip+4 Codes

In addition to the five-digit zip code, the USPS also uses Zip+4 codes. This extended code adds four more digits to the five-digit zip code, providing even more detailed location information. The extra four digits specify a segment of a street, a building, or a group of post office boxes. Using the Zip+4 code can further improve mail delivery efficiency.
