Dial +1. This is the country code for the United States, Canada, and parts of the Caribbean.

The "Mandatory 10-Digit Dialing" Rule
Unlike some rural parts of the US, California has run out of numbers in many regions. This means you must always dial the Area Code, even if you are calling your neighbor across the street.
Major California Area Codes
California has over 35 area codes. Here are the most important ones for business and travel.
| Area Code(s) | Region / City |
|---|---|
| 213 / 323 | Los Angeles (Central) |
| 310 / 424 | Los Angeles (West) |
| 818 / 747 | San Fernando Valley |

Understanding Overlays
Due to high population, many California regions use "overlays" — multiple area codes for the same geographic area. For example, in West Los Angeles, your neighbor might have a 310 number while you have a 424 number.
Tip: Always dial the full 10-digit number (Area Code + Number) in California, even for local calls.

Frequently Asked Questions

What is the area code for San Francisco?
San Francisco primarily uses 415. However, due to high demand, the overlay code 628 was added. Both cover the same geographic area.
What time is it in California?
California is in the Pacific Time Zone (PT). It is 3 hours behind New York (ET) and 8 hours behind London (GMT).
Do I need to dial 1 before the area code?
Yes. In almost all of California, you must dial 1 + Area Code + Number, even for local calls. This is due to the high density of area code overlays.
Can I call California mobiles from abroad?
Yes. US mobile numbers look exactly like landlines (Area Code + 7 digits). There is no special mobile prefix. You dial them the same way: Exit Code + 1 + Area Code + Number.
