California's postal codes, also known as ZIP codes, are a crucial part of the state's infrastructure, facilitating communication, commerce, and connectivity across the region. The United States Postal Service (USPS) assigns these codes to specific geographic areas, ensuring efficient mail delivery and logistical operations. With over 1,100 ZIP codes in California, understanding the structure and application of these codes is essential for residents, businesses, and visitors alike.
Understanding California Postal Codes
California postal codes follow the standard ZIP code format, consisting of five digits. The first digit represents the group of U.S. states, with California's codes beginning with 9. The next two digits signify the regional area, and the final two digits denote the specific post office or delivery area. For example, the ZIP code 94111 corresponds to San Francisco, while 90001 represents Downtown Los Angeles.
The USPS has implemented additional ZIP code formats, including ZIP+4 codes, which provide more precise location information.
