Frequently Asked Questions about the 805 Area Code
Who called me from a 805 number?
A 805 number is assigned to Oxnard, California, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 805 code to look nearby, so a 805 number doesn't prove the caller is local. Recently, 947 unwanted-call complaints were reported to the FTC for numbers showing the 805 code (59% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 805 a scam area code?
No area code is a scam on its own. 805 is a normal, officially assigned code for Oxnard, California. Spam callers spoof local codes to raise the odds you answer, so 805 on your caller ID says nothing about who is really calling. Recently, 947 unwanted-call complaints were reported to the FTC for numbers showing the 805 code (59% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 805 area code?
Repeated calls from different 805 numbers are usually spoofing: a robocaller rotates through 805 numbers so each call looks local and slips past simple blocks. Recently, 947 unwanted-call complaints were reported to the FTC for numbers showing the 805 code (59% 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 805 number?
If you aren't expecting a 805 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 805 area code?
Block a single 805 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 805 code also stops legitimate local calls, so use it only as a last resort.
Where is area code 805?
Area code 805 covers Oxnard and the surrounding area in California, spanning 79 cities with about 1,408,457 residents. No other code overlays this region, so 805 alone identifies the area.
Is 805 a real area code?
Yes. 805 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Oxnard, California. A real code can still show up on spoofed spam calls, so treat unknown 805 calls with normal caution.
What timezone is the 805 area code in?
The 805 area code is in the Pacific Time (PT). Because a number can be kept when someone moves or switches to VoIP, a specific 805 caller may not be in that zone.
How do I call a 805 number from abroad?
From outside the US, dial your country's exit code, then 1 (the US country code), then 805 and the seven-digit number. From a mobile phone you can usually just enter +1 805 followed by the number and let the phone add the exit code for you.
