The Federal Communications Commission is finally cracking down on over 1,200 voice providers for neglecting to follow anti-robocalling rules.

After issuing a warning in December, the FCC on Monday announced it had blocked the providers from US telecommunication networks. "These providers violated FCC rules by failing to maintain accurate Robocall Mitigation Database certifications, thereby shirking their obligations to protect consumers from illegal robocalls,” the agency says.

In December, the FCC threatened to block 2,411 voice providers—many of them little-known VoIP services for businesses and niche use cases—for failing to follow anti-robocall rules in the US and serving as potential conduits for spam calls. 

At the time, the FCC gave the providers 14 days to submit an explanation or remedy the problem. That delay prompted some critics to accuse it of failing to enforce its own rules. 

In its announcement, the commission said it blocked a preliminary group of 185 providers on Aug. 6. The rest were flagged for “missing the required information in their certifications,” despite receiving a notification from the commission, the FCC’s order says.

The same order requires legitimate voice providers to "cease accepting traffic directly from the Companies within two business days." The flagged companies also can't refile into the Robocall Mitigation Database unless they receive consent from the FCC's enforcement bureau.

Other voice providers appear to have filed with the FCC's Robocall Mitigation Database to avoid the crackdown. This database requires companies to explain their anti-robocall efforts. In another case, the voice provider may have deregistered entirely.

With any luck, the crackdown will reduce the number of spam calls in the US. Last month, over 4.3 billion spam calls were made in the country, down 3.1% from the prior month, according to YouMail, which offers robocall blocking.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
