UCaaS built for every U.S. state — HD calling, team meetings, messaging, and more, all on California's 31 area codes. No hardware. No contracts. Live in minutes.
California received three original area codes in 1947 — 213 for Los Angeles, 415 for the Bay Area, and 916 for Sacramento. Growth came in waves as population surged: 714 split from 213, then 408, 619, 818 and many more followed through the 1980s and 90s.
The cellular boom pushed the count further, and California now runs 31 active area codes — more than any other US state. The newest, 628, overlaid 415 in 2015 as San Francisco 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. That is more codes than 30+ entire US states have in total.
California's 31 area codes span the full length of the state — from the Bay Area and Sacramento down through the Central Valley to the San Diego coast.
California is too big for one prefix. Switch between the three regions to find the exact code your customers recognize.
Greater Los Angeles, Orange County, the Inland Empire and San Diego — the densest stretch of codes in the US.
A local 213 or 415 lands as a neighbor, not "spam likely." Recognizable caller ID lifts pickups across every California market.
A 415 or 310 presence tells customers you are established in their market — no physical office or long lead time required.

California has 31 active area codes — more than any other US state. They span three broad regions: Northern California (the Bay Area, Sacramento and the north coast), Central California (the Valley and Central Coast), and the dense Southern California stretch covering Los Angeles, Orange County, the Inland Empire and San Diego.
Choose the code your customers associate with you. A 415 reads as San Francisco, 213 or 323 as core Los Angeles, 619 as San Diego, and 408 as Silicon Valley. Many California metros now run overlay codes (like 628 over 415) on the same geography — callers recognize the city, not the specific overlay.
No. Ajoxi numbers route over the internet, so you can hold a San Francisco 415 or Los Angeles 213 number from anywhere and still show a local California caller ID. Your physical location never changes how the number appears to the people you call.
All 31 California area codes operate on Pacific Time. Ajoxi applies business-hours and routing rules automatically for each number, so your lines behave correctly whether your team sits in California or works remotely from another time zone.
Yes. Beyond the big metros, Ajoxi provisions numbers across Fresno and Visalia (559), Bakersfield (661), the Monterey Bay (831), Santa Barbara and Ventura (805), Palm Springs (760), and the far-north counties around Chico and Redding (530) — each with instant activation and clean caller ID.
Provision a local number on any of the 31 California area codes — instant activation, clean caller ID, Tier-1 routing, and no setup fees.
