Fraudsters often use call spoofing technology to disguise the number they are calling, so it appears to be a local code rather than a legitimate phone number.

Spoofing is also known as caller ID spoofing, which disguises a person's true name and number. Spoofing can be done through popular communication media such as e-mails and phone calls. A fake call is one that says it comes from a specific phone number, person, or company, but it appears on your phone's screen and is actually made by another phone number. However, performing a reverse cell phone lookup for that number is the best way to know whether a number is spoofing or not.

It can be difficult to tell whether a phone number is counterfeit or not, and tracing a counterfeit phone number back to the true numbers may be impossible sometimes.

There is no direct way to detect fake calls, but you can try to track them using the following methods listed in this episode. Telecom providers can trace the original number from which you received the fake call. If you suspect that a telephone number has been forged for illegal or suspicious reasons, you can report the FDA or other organizations to the FTC for investigation.

My guess is that you are looking for several ways to track down a spoofed call. If you're right, this episode is a good resource to give you the knowledge you're looking for to track down fake phone numbers.

I believe that you now have a better understanding of how to trace a fake call and how to actually trace fake numbers.
