How to Dial California, Step by Step
Reaching the West Coast takes only a moment. Work through the steps below to connect with any California landline or cell phone.
Exit Code
Start with the exit code for your country.
00 (Europe/UK)
011 (Asia/Pacific)
(On a mobile, holding 0 produces the + symbol.)
US Code (+1)
Then enter +1. That single code covers the United States, Canada, and several Caribbean nations.
Area Code
Add the three digit California area code, such as 213, 415, or 619.Never optional in CA!
The "10-Digit Dialing" Requirement
Many California regions have simply run out of spare numbers, unlike quieter rural corners of the US. Because of that you must always dial the Area Code, even when you are ringing a neighbor across the street.
Key California Area Codes
There are more than 35 area codes across California. The table below highlights the ones you are most likely to need for business or travel.
| Area Code(s) | Region / City |
|---|---|
| 213 / 323 | Los Angeles (Central) |
| 310 / 424 | Los Angeles (West) |
| 818 / 747 | San Fernando Valley |
| 626 | San Gabriel Valley |
| 415 / 628 | San Francisco |
| 650 | Silicon Valley |
| 510 | East Bay |
| 408 / 669 | South Bay |
| 619 / 858 | San Diego |
| 714 / 657 | Orange County (North) |
| 949 | Orange County (South) |
| 916 | Sacramento |
How Overlays Work
Because so many people live there, plenty of California regions rely on "overlays", where a single geographic area is served by more than one area code. In West Los Angeles, for example, one neighbor may hold a 310 number while the next holds a 424 number.
Tip: In California, always dial all 10 digits (area code plus number), even when the call is local.

Frequently Asked Questions
What is the area code for Los Angeles?
Los Angeles is large enough to need several codes. Downtown and central LA run on 213 and 323, the Westside around Santa Monica and Beverly Hills uses 310 and 424, and the San Fernando Valley is covered by 818 and 747.
What is the area code for San Francisco?
415 is the main San Francisco code. Demand for numbers ran high enough that 628 was layered on as an overlay, and both serve exactly the same area.
What time is it in California?
California sits in the Pacific Time Zone (PT), running 3 hours behind New York (ET) and 8 hours behind London (GMT).
Do I need to dial 1 before the area code?
Yes. Across nearly all of California the pattern is 1 plus area code plus number, even for local calls, because so many overlapping overlays are in use.
Can I call California mobiles from abroad?
Yes. In the US a mobile number looks just like a landline, an area code followed by 7 digits, with no separate mobile prefix. You dial it the same way as any other line: exit code, then 1, then area code, then number.
