City population is shown in full. The share of each city inside 350 is measured from Census tract centroids, not estimated from a rate-center match – so a city split between two codes appears on both, at the fraction each one actually holds. The “% of listed-city population” column uses the full populations of the cities listed here.
What counties does area code 350 cover?

Frequently Asked Questions about the 350 Area Code
Who called me from a 350 number?
A 350 number is assigned to Stockton, California, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 350 code to look nearby, so a 350 number doesn't prove the caller is local. Recently, 235 unwanted-call complaints were reported to the FTC for numbers showing the 350 code (80% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 350 a scam area code?
No area code is a scam on its own. 350 is a normal, officially assigned code for Stockton, California. Spam callers spoof local codes to raise the odds you answer, so 350 on your caller ID says nothing about who is really calling. Recently, 235 unwanted-call complaints were reported to the FTC for numbers showing the 350 code (80% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 350 area code?
Repeated calls from different 350 numbers are usually spoofing: a robocaller rotates through 350 numbers so each call looks local and slips past simple blocks. Recently, 235 unwanted-call complaints were reported to the FTC for numbers showing the 350 code (80% flagged as robocalls). Blocking one number rarely helps; voicemail screening, your carrier spam filter, and the Do Not Call Registry work better.
Should I answer an unknown 350 number?
If you aren't expecting a 350 call, let it ring to voicemail. Legitimate callers leave a message, most robocallers hang up when no one picks up, and answering can mark your number as active and bring more calls.
How do I block calls from the 350 area code?
Block a single 350 number from your recent-calls list (iPhone: tap the number, then Block this Caller; Android: tap the number, then Block or report spam). To cut the volume, turn on Silence Unknown Callers on iPhone or spam protection on Android, enable spam filtering from your carrier, and register at DoNotCall.gov. Blocking the entire 350 code also stops legitimate local calls, so use it only as a last resort.
Where is area code 350?
Area code 350 covers Stockton and the surrounding area in California, spanning 154 cities with about 1,804,069 residents. It shares its area with overlay code 209.
When did area code 350 go into service?
Area code 350 went into service on November 28, 2022. It was added as an overlay of 209, so 350 numbers serve the same area that 209 already covered.
Is 350 a real area code?
Yes. 350 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Stockton, California. A real code can still show up on spoofed spam calls, so treat unknown 350 calls with normal caution.
What timezone is the 350 area code in?
The 350 area code is in the Pacific Time (PT). Because a number can be kept when someone moves or switches to VoIP, a specific 350 caller may not be in that zone.
How do I call a 350 number from abroad?
From outside the US, dial your country's exit code, then 1 (the US country code), then 350 and the seven-digit number. From a mobile phone you can usually just enter +1 350 followed by the number and let the phone add the exit code for you.
