Area code 510 envelops a cluster of East Bay cities in Northern California, extending its reach to vibrant locales like Hayward and Fremont in both west Contra Costa and Alameda counties. However, the inland gems of Alameda County—Dublin, Livermore, Pleasanton, and Sunol—fall under the jurisdiction of the 925 area code. Calculated by the California Department of Finance, the East Bay area houses a dynamic population of approximately 2.6 million individuals.

The economic tapestry of the region is woven with threads of diversity, finding its foundations in technology, construction, real estate, manufacturing, professional services, trade, and marine cargo transport. Notably, Hayward boasts a thriving manufacturing sector, with prominent players like PepsiCo and Annabelle Candy contributing to the city’s industrious pulse. The tech landscape also thrives, with the presence of entities like Dust Networks and Christensen Controllers, creators of the Sonic Palette musical instrument.

Berkeley, embraced by area code 510, is synonymous with the esteemed University of California, Berkeley—a stronghold of education and innovation and the city’s premier employer. Beyond academia, Berkeley’s culinary scene shines through Chez Panisse, hailed as the birthplace of California Cuisine, and the aromatic legacy of Peet’s Coffee & Tea.
