Questions about California area codes
- How many area codes does California have?
- 41, the most of any state. Many areas have more than one, because a second or third code can overlay the first and cover the same ground.
- What is the newest California area code?
- 357, an overlay on 559 in the central San Joaquin Valley that started in March 2025. 837 in northeastern California and 738 in Los Angeles started in the months before it.
- What is an overlay area code?
- An overlay is a new code laid over the same area as an existing one. 424 and 310 cover the same part of Los Angeles County, for example. Numbers in that area can carry either code.
- Does all of California use the same time zone?
- Yes. Every California area code is on Pacific time.
- Can I get a specific California area code like 310 or 949?
- We ask for the code you want when we set up your number. Codes in busy areas such as Los Angeles can run short, and some numbers cannot be approved for a business. If your first choice is not available, we set up a toll-free number so your line still goes live.
