Coverage
Where does the 510 area code apply?
The 510 area code serves the western portions of Alameda and Contra Costa counties in California's East Bay — Oakland, Berkeley and the cities around them. It was created in September 1991, when it split off from the original 415 area code, which at the time covered the entire San Francisco Bay Area.
In 1998, the eastern portions of Alameda and Contra Costa counties were carved out to form the separate 925 area code, narrowing 510 to its present-day East Bay footprint. The overlay code 341 was then added to the same territory in 2019 to meet continued demand for numbers. A 510 number on Bloom AI cloud telephony keeps your business anchored in Oakland, wherever your team works from.

Same territory
510 or 341: which should you choose?
Both area codes cover the same East Bay territory. 510 is the historic code, in service since 1991; 341 is the newer overlay added in 2019. In practice, the choice mainly depends on which numbers are available when your line is activated.
Why 510
