Caller ID Can Be Hacked

If you rely on caller ID to screen calls, you should be aware that the number you see cannot always be trusted.

There are a few services available that let people choose the caller id number that appears when they make a phone call.

Telemarketers and collections agencies are not allowed to change their number, but some still do.

I share this secret because caller id spoofing is becoming popular among fraudsters. You should be weary of any caller asking you for something, especially money or personal information. If a caller claims to be from your financial institution or another company that requires personal information, ask them some information that confirms they are who they say they are. For example, if it’s your cell phone company, ask them which calling plan you’re on.

Here are some of the caller id spoofing services:

• Telespoof
• Spoofcard
• Phone Gangster
• Spooftel
• Spoofapp (for iPhone, BlackBerry or Android)

Due to potential abuse of these services, the state of Florida outlawed caller id spoofing services for a couple years, but that decision was recently overturned. Others states are working on laws to make them illegal, but for now, they are legal in all states.

There are some legitimate uses for this service. If your profession requires that you make calls from home or cell, this service could be used to show your office number instead of your personal number.

There is a cheaper option called *67. Dial that before you dial a phone number and it blocks your number from being displayed for that call — it’s free in most places.
