The Senate passed a bill on Thursday meant to crack down on the billions of spam robocalls Americans receive every month.

The bill, approved in the House earlier this month, now goes to the desk of President Donald Trump for his signature. The TRACED Act , for Telephone Robocall Abuse Criminal Enforcement and Deterrence, requires phone companies to offer free call-blocking technology and requires them to verify that the number calling someone is real.

The tool would provide a deterrent to scammers who often call using fake numbers meant to look like the call is coming from a reputable caller, such as the IRS, in order to trick people.

The Robocall Index estimates that approximately 5 billion spam calls were made last month, amounting to about 7 million calls an hour. Almost half, 46%, of the calls were scams.

The bipartisan legislation gives regulators more time to find scammers and levy fines against those who are caught, according to its sponsors. They say it also brings the relevant federal agencies and state attorneys general together to eliminate obstacles to prosecuting the most egregious offenders.

The Federal Communications Commission can levy civil penalties of up to $10,000 per call on people who defy telemarketing restrictions. Additionally, the window for taking action against violators has been extended to four years after the call is placed.

While the bill won't stop the billions of phone calls, it will allow the industry and regulators to make an impact.

Sen. John Thune, South Dakota Republican, introduced the bill in January. He said in a statement that while the scammers are a "nuisance," robocallers also prey on vulnerable populations, especially seniors.
