Is a Call From 415 a Scam?
Most 415 calls are from real people and companies in San Francisco and Marin. Many tech firms are based here, so scammers spoof 415 numbers for fake tech support, fake job offers and fake account alerts.
Watch for these warning signs:
- Someone who says they are from the IRS, Social Security or a court and demands payment
- Tech support calls about a virus on your computer
- Investment or crypto offers from a company you do not know
- Texts that ask you to click a link to fix a billing problem
Caller ID can be spoofed, so the number on your screen does not prove where a call comes from.

- Let it ring out and check the voicemail.
- Search the full number online before you call back.
- Block the number and report it.
- Report scam calls at reportfraud.ftc.gov and register at donotcall.gov.
