The Current Count: More Than Meets the Eye
As of 2024, there are over 41,000 ZIP codes in the United States. However, this number isn’t static. The USPS continually adjusts and adds ZIP codes to accommodate population shifts, new developments, and evolving delivery routes.
What’s in a ZIP Code? The Anatomy of a Postal Identifier
ZIP stands for “Zone Improvement Plan.” Introduced in 1963, ZIP codes were designed to streamline mail sorting and delivery. Each ZIP code represents a specific geographic area, ranging from small towns to large cities.
A standard ZIP code consists of five digits. The first digit indicates a broad geographic region, while the following digits narrow down the location. For example, ZIP codes starting with “0” represent the Northeast, while those starting with “9” represent the West Coast.
Beyond the Basics: ZIP+4
To further enhance accuracy, the USPS introduced the ZIP+4 system. This adds four digits to the standard ZIP code, pinpointing a specific delivery route, building, or group of addresses.
