Unlocking California’s Geography: A Comprehensive Guide to 3-Digit Zip Codes
The United States Postal Service (USPS) utilizes a system of zip codes to streamline mail delivery. In California, a unique and valuable tool exists: the 3-digit zip code map. This map, often referred to as a "zip code prefix map," provides a visual representation of the state’s geography, dividing it into distinct regions based on the first three digits of zip codes. While seemingly simple, this map holds a wealth of information, offering insights into demographics, economic activity, and geographic distribution within the state.
Understanding the Structure of 3-Digit Zip Codes
A 5-digit zip code, the standard format, consists of five numbers representing a specific geographic area. The first three digits, known as the "zip code prefix," broadly define a region. In California, these prefixes range from 900 to 961, each encompassing a significant portion of the state.
