925 Area code

The 925 area code serves the inland regions of the East Bay counties of Contra Costa and Alameda. This is a highly urbanized region, and home to approximately 2.8 million people.

The region sustains a mix of industries, ranging from manufacturing, retail, and professional services, to farming and various small and large businesses. One of the East Bay cities that enjoys sustained economic growth is Pleasanton. With the development of a number of business parks like Hacienda Business Park, the city attracts major companies, which build their headquarters in the area.

Another notable city in the region is Walnut Creek, which has a vibrant shopping and cultural scene and is home to The California Symphony. One of the best symphonies in the U.S., it attracts both veteran and aspiring musicians to the city.

Not far from San Francisco, the city of Concord has become a great residential option for commuters. With more affordable homes and accessibility through the BART commuter train, it’s a simple and affordable way to enjoy the benefits of working in San Francisco without the prohibitive costs of living there.

Other cities in the area code 925 location include Antioch, San Ramon, and Livermore.

The 925 area code was introduced in 1998 as an offshoot of the 510 area code, with the intention to better serve the expanding outer East Bay region of the San Francisco Bay Area. It’s since served cities such as Concord, Walnut Creek, Antioch, and Livermore, covering suburban and rural areas in Contra Costa and Alameda counties.

The 925 area code falls within the Pacific Time Zone (PT) in the United States, covering much of the outer East Bay region. Using a 925 number is therefore ideal for any business that wants to effectively serve customers who work in PT.
