History and Overview of California Area Codes
California is a state known for its diverse population, booming industries, and sprawling cities. With such a vast territory, it comes as no surprise that the state is divided into multiple area codes to handle the high volume of telephone calls.
Understanding the history and overview of California area codes can help residents and visitors navigate the telecommunications landscape more effectively.
Origins of the area code system
The origins of the area code system can be traced back to the early days of telephone communication. In the mid-20th century, as telephone usage grew rapidly, the need for a standardized numbering system became evident.
The North American Numbering Plan (NANP) was established in 1947, dividing North America into different numbering plan areas (NPAs).
California was initially assigned three area codes: 213, 415, and 916. However, as the population and telephone usage continued to increase, more area codes were added to meet the demand. Today, California has over 30 area codes, serving different regions within the state.
How California area codes are assigned
The California Public Utilities Commission (CPUC) is responsible for assigning and managing area codes in the state. When a new area code is needed, the CPUC follows a process that includes public input and coordination with industry stakeholders.
There are several factors that determine the need for a new area code. These include population growth, increased demand for telephone numbers, and the exhaustion of existing area code resources. The CPUC carefully evaluates these factors to ensure efficient utilization of telephone resources while minimizing disruption to residents and businesses.
When a new area code is introduced, it is typically done through an overlay plan. This means that the new area code is added to the same geographic region as an existing area code. Existing numbers retain their current area code, while new numbers are assigned the new area code.
This approach helps avoid the inconvenience of changing phone numbers for existing customers.
It’s important to note that the introduction of new area codes does not affect the cost of telephone calls. Local and long-distance calling rates remain the same, regardless of the area code dialed.

Recent California Area Code Splits and Changes
Over the years, the demand for telephone numbers in California has grown significantly, leading to several area code splits and changes. These changes are necessary to accommodate the increasing population and the ever-expanding telecommunications network.
Let’s take a closer look at some of the recent area code splits and changes in California.
New Area Codes from Splits since 2000
Since the year 2000, California has witnessed several area code splits, resulting in the introduction of new area codes. One such example is the split of the original 415 area code, which led to the creation of the 628 area code in 2015.
This split became necessary due to the rapid growth of mobile phones and other telecommunication devices in the San Francisco Bay Area.
Another notable example is the split of the original 213 area code, which resulted in the addition of the 323 area code in 1998. This split was necessary to meet the increasing demand for telephone numbers in the Los Angeles area.
It’s worth mentioning that these new area codes from splits have been successfully implemented, allowing for the continued growth and development of California’s telecommunications infrastructure.
Pending and Approved Area Code Changes
In addition to the past splits, there are also pending and approved area code changes in California. These changes are necessary to ensure that the state’s telephone numbering plan remains efficient and sufficient for future needs.
One pending area code change is the addition of the 840 area code in the overlay complex of the 909 area code. This change is expected to take effect in 2022 and will provide additional telephone numbers for the Inland Empire region, which includes parts of San Bernardino and Riverside counties.
Another approved area code change is the overlay complex of the 949 area code, which will introduce the 949/714 overlay. This change will provide additional telephone numbers for Orange County and parts of Los Angeles County, ensuring that the growing population in these areas can continue to connect and communicate.

Identifying Scam Calls with Area Codes
With the rise in scam calls, it is important to stay vigilant and be able to identify potential fraudsters. One way to do this is by paying attention to the area codes displayed on your caller ID. Scammers often use spoofed area codes to make it appear as if their calls are coming from a legitimate source.
Here are some tips to help you identify scam calls based on area codes:
Watch out for spoofed area codes
Scammers have become increasingly sophisticated in their methods, including the ability to manipulate the caller ID system to display a different area code than the one they are actually calling from. This is known as “spoofing.”
By using a local area code, scammers try to gain your trust and make you more likely to answer the call. It’s important to be cautious and not solely rely on the displayed area code to determine the legitimacy of a call.
Pro tip: If you receive a call from an unfamiliar area code, consider using a reverse phone lookup service to verify the caller’s identity. Websites like Whitepages or Spy Dialer can provide information about the caller’s location and whether it’s a known scam.
Red flags for scam calls
While area codes can be one clue to identifying scam calls, there are other red flags to watch out for. These include:
- High-pressure tactics: Scammers often use fear or urgency to manipulate their victims. If the caller is pressuring you to provide personal information or make immediate payments, it’s a sign that something might be wrong.
- Unsolicited requests for sensitive information: Legitimate organizations will not ask you to provide sensitive information like your Social Security number or banking details over the phone. Be cautious if a caller asks for such information.
- Too good to be true offers: If a caller promises you incredible deals or opportunities that seem too good to be true, it’s likely a scam. Remember the old saying, “If it sounds too good to be true, it probably is.”
Remember, scammers are constantly evolving their tactics, so it’s important to stay informed and be cautious when receiving calls from unfamiliar area codes. If you suspect a scam call, hang up immediately and report it to the Federal Trade Commission (FTC) or your local authorities.
Future California Area Code Projections
Predicting the need for new area codes
As California’s population continues to grow at a rapid pace, the need for new area codes is inevitable. The demand for phone numbers is increasing as more and more people move to the state or start new businesses.
According to the California Public Utilities Commission, the current area codes are reaching their capacity, and it is projected that new area codes will be required in the near future.
Predicting the need for new area codes involves analyzing demographic data, population trends, and economic forecasts. By closely monitoring these factors, experts can estimate when the current area codes will run out of available phone numbers.
This enables them to plan ahead and propose new area codes in a timely manner, ensuring that there is no shortage of phone numbers for residents and businesses.
Several factors contribute to the need for new area codes. The rise of mobile devices, the proliferation of internet-connected devices, and the increasing popularity of telecommunication services all contribute to the growing demand for phone numbers.
Additionally, the expansion of businesses and the influx of new residents to California further exacerbate the need for additional area codes.
Proposed timeline for additions and splits
The California Public Utilities Commission has proposed a timeline for the addition of new area codes and potential splits of existing area codes. This timeline takes into account the projected growth of the state’s population and the estimated depletion of available phone numbers in each area code.
According to the proposed timeline, new area codes are expected to be introduced in the next few years. These area codes will be assigned to specific regions within California that are experiencing high population growth and increased demand for phone numbers.
The timeline also includes the possibility of splitting existing area codes to accommodate the growing demand.
It is important to note that these proposed additions and splits are subject to approval by the California Public Utilities Commission.
