Question 1

Is area code 831 a scam?

Accepted Answer

Area code 831 itself is not a scam — it is a legitimate North American area code (California). However, scammers frequently spoof real area codes, including 831, so individual calls or texts can still be fraudulent. Judge each call on its content, not its area code.

Question 2

Why did I get a call from 831?

Accepted Answer

It may be a legitimate caller from California, an automated/robocall, or a spoofed number designed to look local ("neighbor spoofing"). If you don't recognize the number, let it go to voicemail and look it up.

Question 3

How do I know if a 831 call is spoofed?

Accepted Answer

You can't tell from caller ID alone — spoofing makes a call appear to come from any number, including your own area code. Warning signs: unsolicited calls claiming to be the IRS, your bank, or tech support; pressure to act immediately; or requests for payment in gift cards or crypto.

Question 4

How do I stop spam calls from 831?

Accepted Answer

Don't answer unknown numbers; block the specific number; register on the National Do Not Call Registry (donotcall.gov); enable your carrier's spam filtering; and consider a call-blocking app. Report unwanted calls to the FTC at reportfraud.ftc.gov.
