Tips For Reporting Unwanted Phone Calls


Many people have received unwanted calls from unknown callers at one time or another. Callers increasingly use modern technology--including throw-away cell phones and “spoofed” telephone numbers--to conceal the location from which they are calling. In many cases, the calls are made by criminal enterprises attempting to commit theft or fraud. In most cases, these criminals live in other states or countries.

An unwanted call may appear on caller ID as a “private” or “unknown number,” or the phone number that appears on caller ID may be a fake number. People who call back the phone number that appears on their caller ID often receive a message that the number is busy or disconnected. In other cases, the phone number may work for a short period of time while it is answered by the criminal.

If you receive unwanted calls, you should file reports with the following agencies and provide as much information as you can about the time, date, and nature of the call:

FEDERAL TRADE COMMISSION. You may list your number on the federal “Do Not Call Registry” online at, External Link or by calling 1-888-382-1222. Legitimate companies usually honor the “Do Not Call” list and respect the wishes of people on the list not to be called. Criminals, however, typically do not honor the “Do Not Call” list. These criminals are bent on stealing people’s money (a crime) and are not dissuaded by the fact that a person’s number is on the “no call” list.

The “Do Not Call” law is a federal law and is enforced by the Federal Trade Commission (“FTC”). External Link You should report violations of the federal “Do Not Call” law to the FTC as follows:
