The 350 area code is a relatively new addition to the California telephone numbering system, introduced in late 2022 to meet the growing demand for phone numbers in the rapidly developing Central Valley region. This article explores the history of the 350 area code, delves into the reasons for its implementation, and examines its impact on businesses and residents. It also provides a detailed overview of the area covered by the 350 area code, including its major cities and counties.
Before the 350 area code, the 209 area code served the entire Central Valley region. However, with a burgeoning population and the rise of cell phones and internet-connected devices, the 209 area code faced the prospect of running out of available phone numbers. To prevent this, the California Public Utilities Commission (CPUC) approved the addition of the 350 area code as an overlay1. This decision was made in part due to the 209 area code's earlier transition to mandatory 10-digit dialing in 2021, which paved the way for a smoother overlay implementation2.
An overlay adds a new area code to the same geographic area as an existing one, allowing both area codes to co-exist and serve the same region1. This approach contrasts with the older practice of geographically splitting an area code, which required existing customers to change their phone numbers3. The 350 area code officially became active on November 28, 20222. It was the 445th area code in service in the United States, one of 19 new area codes introduced that year, and is currently one of 39 area codes in California3.
The 350 area code was implemented to ensure a continued supply of phone numbers in the Central Valley2. The region's population growth and the increasing demand for telecommunication services, including landlines, cell phones, and internet-connected devices, were rapidly depleting the available numbers within the 209 area code2.
Traditionally, when an area code ran out of numbers, it was split geographically, creating two smaller area codes with distinct boundaries3. However, this method disrupted existing customers, who had to change their phone numbers. To avoid this inconvenience, the CPUC opted for the overlay method, allowing residents and businesses to keep their existing numbers while providing a new pool of numbers with the 350 area code3.
The 350 area code covers a significant portion of California's Central Valley, sharing the same geographic footprint as the 209 area code4. This region encompasses a diverse range of communities, from bustling cities to quiet rural towns, and includes all or parts of the following 13 counties: 5
| County | |---|---| | Alameda | | Alpine | | Amador | | Calaveras | | El Dorado | | Fresno | | Madera | | Mariposa | | Merced | | Sacramento | | San Joaquin | | Stanislaus | | Tuolumne |
Major cities within the 350 area code include Stockton, Modesto, Tracy, Merced, and Turlock2. The region is also home to Yosemite National Park and Kirkwood Mountain Resort1. The 350 area code operates within the Pacific Time Zone6.
Stockton, one of the major cities in the 350 area code, stands out for its agricultural prominence. It's situated in one of the world's most productive agricultural regions, known for its diverse crops, including grapes, almonds, and tomatoes6. Beyond agriculture, Stockton boasts a robust transportation network, with well-developed highways, railroads, and ports, making it a strategic location for logistics and distribution businesses6.

However, there are also some potential drawbacks:
As a relatively new area code, the 350 area code is still in its early stages of integration within the Central Valley's telecommunications network6. Since its introduction, telecommunication providers have been steadily assigning 350 numbers to new customers and those requesting additional lines1. This gradual rollout has facilitated a smooth transition and minimized disruptions for residents and businesses.
The 350 area code has also led to a shift in dialing habits, as residents and businesses have adapted to 10-digit dialing for all local calls2. This change, while initially requiring some adjustment, has become the standard practice in the region.
