Why This Overlooked Area Code 650 Counts More Than You Expect in the Bay Area When you think of the Bay Area’s iconic area codes—like 415, 858, or 925—the number 650 rarely jumps to the forefront. Yet, this under-the-radar code holds far more significance than its humble appearance suggests. From its growing role in tech innovation to its unique cultural footprint, Area Code 650 is quietly becoming one of the most impactful zones in the San Francisco Bay Area. ### Where Is Area Code 650 Located Anyway? Perched in the heart of Silicon Valley, area code 650 largely covers Frederick County’s northern reaches and portions of San Mateo County, including key suburbs like Cupertino’s inland neighborhoods and parts of East Palo Alto. Though often overshadowed by the quintessential Bay Area hubs, this region is home to a dynamic mix of startups, tech commuters, and rising commercial centers—all quietly identifying with the 650 prefix.
