Understanding California Zip Codes

What is a Zip Code?

A zip code (Zoning Improvement Plan code) is a postal code used by the United States Postal Service (USPS). Zip codes help the USPS efficiently sort and deliver mail. The basic zip code is a five-digit number, and there's also an extended zip code (ZIP+4) that adds four more digits for even more precise delivery.

The Structure of California Zip Codes

California zip codes primarily fall within the 90001 to 96162 range. These numbers are generally organized geographically, although there are exceptions. In our analysis, we've observed that lower zip codes are typically found in Southern California, while higher zip codes are in Northern California.
