California Zip Codes: Complete List & Lookup

Finding the correct zip code in California can be essential for various tasks, from sending mail to filling out online forms. This guide provides a comprehensive overview of California zip codes, including how they work, how to find them, and some useful resources.

Understanding California Zip Codes

Zip codes, or Zone Improvement Plan codes, are numerical postal codes used by the United States Postal Service (USPS) to streamline mail delivery. California zip codes fall within the range of 90001 to 96162. Each zip code designates a specific geographic area, which can be a city, a neighborhood, or even a single building.

How Zip Codes Work

Zip codes are composed of five digits, sometimes followed by a four-digit add-on code. The first digit represents a broad geographic area of the United States, while the subsequent digits narrow down the location to a specific region, city, or postal delivery zone. The four-digit add-on, known as ZIP+4, further pinpoints a specific street, building, or group of mailboxes.

Why are Zip Codes Important?

• Efficient Mail Delivery: Zip codes enable the USPS to sort and deliver mail more efficiently.
• Location Data: Businesses and organizations use zip codes for data analysis, marketing, and logistics.
• Online Forms: Many online forms require a zip code to verify your location or provide accurate information.
