Understanding this system is crucial for navigating the region, whether for personal, professional, or business purposes. This article provides a comprehensive guide to Southern California’s zip code system, exploring its structure, significance, and practical applications.
The Structure of Southern California’s Zip Code System
The United States Postal Service (USPS) established the zip code system in 1963 to streamline mail delivery.

The region’s zip codes are five-digit numerical codes, with the first three digits representing the primary delivery area and the last two digits indicating a specific location within that area.
Key Zip Code Regions in Southern California
Southern California’s zip code system encompasses a vast geographic area, including major cities like Los Angeles, San Diego, San Bernardino, Riverside, and Orange County. Each city and county has its own unique set of zip codes, often reflecting distinct neighborhoods, business districts, or geographical features.
