Geographic Coverage
The San Gabriel Valley is home to roughly 1.8 million residents, making it one of the most populous suburban regions in the United States. The local economy includes healthcare, education, retail, and a significant concentration of restaurants and small businesses. Pasadena anchors professional and research activity through institutions such as Caltech and the Jet Propulsion Laboratory. The region also supports a large manufacturing and logistics sector tied to the broader Los Angeles metropolitan economy.
Population and Business Context
Area code 626 was created on January 25, 1997, when it split from area code 818. Prior to that split, the San Gabriel Valley shared the 818 code with communities in the San Fernando Valley. The division was necessary due to rapid population growth and increasing demand for telephone numbers in the Los Angeles metropolitan area. No additional overlays have been introduced into the 626 numbering plan area as of 2024, leaving 626 as the sole geographic area code for the region.
Area Code History
Calls to and from area code 626 require 10-digit dialing, meaning you must enter the full area code plus the seven-digit local number. This rule applies to local calls within the 626 area as well as calls placed from other California area codes. There is no overlay code currently sharing the 626 geographic footprint. When dialing from outside the United States, callers must first enter the country code for the US and Canada, which is 1, followed by 626 and the seven-digit number.
