You get a call, look at the caller ID, and see that your own number is calling. No, this isn't an alternate reality where your future self is calling the present you. It's a scammer making an illegal robocall. Technology makes it easy for scammers to fake or “spoof” caller ID information.
Subsequently, one may also ask, can I block my own number from calling me?
How to temporarily block your number on any phone. Keying *67 before the phone number will block your caller ID on the call you're making — and it works for both mobile and landline phones. Whoever you call will see "private number," "unavailable," or something similar on their caller ID instead of your phone number.
Secondly, is my phone number being spoofed?
The surest sign that someone is using your number to make spoofed calls is if you start getting multiple calls or SMS responding to communication you never initiated. If you've never tried to contact these people, then your phone number is probably being spoofed.
Why is my phone calling people?
This may be someone spoofing you, which is changing the caller ID their phone sends so that it's your number. So for caller ID, the person making the call pays, so they get to control the caller ID.
What happens if you answer a call from your own number?
Under the Federal Truth in Caller ID Act of 2009, using caller ID spoofing to defraud someone is a crime. Theft of personal and financial information is a crime and should be reported to local authorities. It is generally a good idea not to answer a phone call that appears to be from your own phone number.
