There are two different scenarios in which a call or text may be reported. If you have received unsolicited calls and texts but have not lost any money, you can report them at DoNotCall.gov. If you did lose money because of a scam call or text, then you need to report it at ReportFraud.ftc.gov. Your report should include your number, the number that appears from the call or text (even if the number is likely fake), and the date and time of the call. Always make sure to report the number the call came from in case it happens to be the real number of the caller. Fake numbers can also sometimes be traced back to the real caller by the FTC and law enforcement.
Reporting unsolicited calls and texts helps the FTC and law enforcement identify scammers based on their calling patterns. Those who have placed an illegal robocall or text may be fined up to $43,792 per incident. The FTC works to stop illegal calls by suing companies responsible for making the calls and working with law enforcement to track down robocallers.
