A 415 opens Bay Area B2B doors
San Francisco buyers screen out 800-numbers and out-of-state cells. A 415 prefix signals "you're local, you're serious" — essential for SaaS and startup sales.
Get a 213 that signals downtown LA, a 415 that says Bay Area tech, or a 310 that reads Beverly Hills. California's 36 codes carry weight — pick the one your customers will recognise on caller ID.
California has 36 active area codes — 213, 310, 408 and 33 more. You can get a virtual California phone number from any of these area codes through CallMama without a US address or SIM card.
California received three original area codes in 1947: 213 for the Los Angeles basin, 415 for the San Francisco Bay Area, and 916 for Sacramento and the inland north. For a decade those three carried the whole state.
Growth came in waves: 714 split from 213 in 1951, 408 and 707 split from 415 in 1959, 619 from 714 in 1982, and 818 from 213 in 1984 for the San Fernando Valley.
The 1990s cellular boom added 510, 310, 909, 562, 949 and many more. California now runs 36 active area codes — the most of any US state. The newest, 669, overlaid 408 in 2012 as Silicon Valley exhausted its number supply.
Los Angeles County alone uses nine different area codes — 213, 310, 323, 424, 562, 626, 661, 747 and 818 — covering more than 10 million people across 4,000 square miles. That's more codes than 30+ entire US states have in total.
