What is Caller ID spoofing?

If you glance at your Caller ID and pick up the phone thinking you're talking to a friend or neighbor only to find a telemarketer on the line, you've probably been the victim of "spoofing."

"Spoofing" is a way companies conceal their identity by changing how their name and number appear on your Caller ID. There are unique instances (e.g., domestic violence shelters) when callers do this for legitimate security reasons. More often than not, however, businesses have less honorable motives. For instance, it's becoming more common for companies to spoof local numbers, making it appear that they're someone calling you from down the street, or at least in the same city. Their aim is simply to get you to pick up the phone and listen to their pitch or scam.

How to protect yourself

Spoofing is a growing problem and something we would like to stop. Unfortunately, companies that spoof typically use specialized internet software, and their calls either originate outside our network or aren't carried on our network at all. As a result, spoofed calls are usually untraceable and there's not a lot we can do to stop them.

However, there are things you can do to protect yourself and control who's able to call your home:

  1. Use a calling feature to block incoming calls. We offer a variety of privacy-focused calling features that you might find useful. When you purchased your phone service, you likely selected several calling features as part of your service package. If you've found a calling feature that you'd like to use that's not currently activated in your package, you can add it. You may be able to do this for no extra cost or purchase the feature a la carte. 
  2. Try to trace the harassing calls. It's usually difficult to trace spoofed calls. However, if you successfully do it three times, we have more options for solutions, including working with law enforcement. The Call Trace feature is available in most areas. It's pre-installed on your phone line, and you're only charged if you successfully complete the trace. 
  3. Get an unpublished (private) listing. With a private listing, your name, address, and phone number aren't included in the printed phone book and aren't available through Directory Assistance. There is a one-time setup fee as well as a monthly charge for this service.  
  4. Change your telephone number. While we understand this is probably a last resort, this can be a useful solution for some. In most areas, we'll change your telephone number for free one time if you're receiving harassing calls.
