Next, let’s look at why you might need a 510 area code.

Where is area code 510?

The 510 area code is located in the East Bay of the San Francisco Bay Area in California. It includes the cities of:

  • Oakland
  • Berkeley
  • Fremont
  • Hayward
  • Richmond
  • San Leandro
  • Alameda
  • Union City
  • Castro Valley

The 510 area code was one of the original area codes established in 1947 and it originally covered the entire East Bay area. In 1991, the 510 area code was split, with the northern portion becoming the 415 area code and the southern portion becoming the 510 area code. Seven years later, the eastern part was then split off into the 925 area code.

Today, the 510 area code covers most of Alameda and Contra Costa counties. It's located just east of the 650 area code.
