house Bill H.R. 3670

Hanging Up On Phone-Spoofers

Argument in favor

Protects U.S. phone owners from foreign and domestic scammers trying to steal personally identifying information.

Argument opposed

This bill could potentially criminalize people who simple want their caller identification information to remain anonymous.

What is House Bill H.R. 3670?

This bill would order the Federal Communications Commission (FCC) to crack down on “spoofing services.” The crackdown would come in the form of an attack on an Act that has been on the ledger for decades — the Communications Act of 1934.

In this context, a “spoofing service” is a service that allows an individual to manipulate a caller identification service to relay misleading or false caller identification information. This is typically done by individuals who are trying to defraud or otherwise harm strangers, or to simply block the identity of the person making a call. For example, an identity thief can use a spoofing service to pretend to be a bank or a government agency, allowing them to collect sensitive personal information from customers.

Under the current Communications Act, it’s illegal for a caller identification service to transmit misleading caller identification information. However, this Act only applies to services within the U.S. In addition to giving the FCC more teeth to regulate this practice, this bill would make it illegal for a person to knowingly transmit inaccurate caller identification information to individuals living in the U.S.

H.R. 3670 would also revise the definition of “caller identification information/service” so that it includes text messages. It would also prohibit various voice-over-Internet services that can be used to transmit false identification information.

More Information

Of Note:

Spoofing services that mask caller identification are often used by scammers to trick people into divulging sensitive information over the phone. But they’re also used semi-legally by telemarketers to avoid being reported to the FCC’s do-no-call list.

They’re also used to play pranks. But these aren’t always innocent jokes. In San Diego, scammers pretending to be sheriff employees contacted residents and claimed they had warrants out for their arrest, threatening them with jail time if they didn’t pay fines.

While several services offer protection from spoofing, there’s currently a wide loophole that scammers can exploit: calling individuals using their own phone number. As Aaron Foss, the operator of a robocall-blocking service puts it:

“We don’t want to block good calls and who would call themselves?”

    The TRACE Act would crack down on illegal robot callers. This one of those rare things that I think every can support. Don’t let it get bogged down.
