California Zip Codes: Search By City & County

California, the Golden State, is a vast and diverse region with a complex network of zip codes. Figuring out the right zip code is crucial for everything from sending mail and packages to finding local services and understanding demographics. This guide provides a comprehensive overview of California zip codes, offering tools and tips for easy searching.

Understanding California Zip Codes

Zip codes, or Zone Improvement Plan codes, are five-digit numbers created by the United States Postal Service (USPS) to streamline mail delivery. In densely populated areas, zip codes might cover just a few blocks, while in rural areas, they can encompass entire towns.

How Zip Codes Work

The first digit of a zip code represents a broad geographic area of the U.S. The following two digits designate a specific region or city within that area. The last two digits pinpoint a particular post office or delivery zone.

Different Types of Zip Codes

• Standard Zip Codes: These are the most common, used for residential and business addresses.
• PO Box Zip Codes: Assigned to post office boxes.
• Unique Zip Codes: Used for single organizations or buildings with high mail volume.
• Military Zip Codes: Used for Army, Navy, and Air Force installations.
