If you answer the phone and hear a recorded message instead of a live person, it's a robocall.  We’ve seen a significant increase in the number of illegal robocalls because internet-powered phone systems have made it cheap and easy for scammers to make illegal calls from anywhere in the world, and to hide from law enforcement by displaying fake caller ID information.

To date, the FTC has brought more than a hundred lawsuits against over 600 companies and individuals responsible for billions of illegal robocalls and other Do Not Call violations.

The FTC also is leading several initiatives to develop technology-based solutions. Those initiatives include a series of robocall contests that challenge tech gurus to design tools that block robocalls and help investigators track down and stop robocallers. We’re also encouraging industry efforts to combat caller ID spoofing. Here’s the FTC’s game plan to combat robocalls:

  • continue aggressive law enforcement
  • build better tools for investigating robocalls 
  • coordinate with law enforcement, industry, and other stakeholders
  • stimulate and pursue technological solutions.
