History of the 415 Area CodeDetailed View
The 415 area code serves San Francisco, California and surrounding Marin County communities. Established in 1947 as one of California's original area codes, it operates on Pacific Time with overlay code 628 serving the same geographic region.
The 415 area code holds a special place in California telecommunications history as one of the original three area codes established in 1947, alongside 213 (Los Angeles) and 916 (Sacramento). Initially covering a vast territory from San Francisco north to the Oregon border, 415 has undergone numerous splits as the Bay Area population exploded. The first major split occurred in 1958 with 209 taking the Central Valley, followed by 408 for San Jose in 1959. The 707 split the same year, carving out the North Bay. As the East Bay grew, 510 was created in 1991, and the Peninsula got 650 in 1997. By 2015, number exhaustion necessitated the 628 overlay, allowing new numbers in the same geographic area. Today, 415 remains synonymous with San Francisco's identity and serves as a prestigious business designation.
