U.S. consumers received just over 4.8 billion robocalls in March, marking a 7.9% increase from February, according to YouMail’s latest Robocall Index.  

March averaged 155.0 million robocalls/day and 1,794 robocalls/second, down 2.5% from February’s average of 159.0 million robocalls/day and 1,840 robocalls/second. This means almost all of the increase in March was due to March having three more days than February. However, this was a 12.7% increase on a year-over-year basis from March 2024.

“Robocall volume in March continues the trend of 2025 starting off at a monthly volume roughly 10% higher than the same period in 2024.” said YouMail CEO Alex Quilici. “This trend is not what consumers were hoping for, and there continues to be a need for apps and services that protect consumers.”

These latest figures are provided by YouMail, a totally free app to protect consumers from unwanted or dangerous calls, texts, and voicemails. The figures are determined by extrapolating from the robocall traffic attempting to get through to YouMail’s millions of active users.

All Categories of Robocalls Increased in March

March’s Robocall volume saw a rise in all categories; however, the overall make up of robocalls didn’t change during the month.   Unfortunately, due to the volume increases, there were almost 2.6 billion unwanted spam and telemarketing calls, making up 54% of all the robocalls in the month.

March 2025’s Most Annoying Robocalling Campaign

The most problematic robocall campaign in March targeted people to switch to high-deductible medical plans, like calls from this number, which leaves messages roughly like this:

When they’re angry they lash out they take it out on you. They take it out on your health care, your $350 a week health benefit is about to be gone permanently they want to wipe it out before you even realize what’s happening you have days maybe hours before Trump and JD Vance shut this program down for good. They already lost to Zelensky, now they’re making you pay for it. If you’re under 64 making less than $50,000 and not on Medicare or Medicaid you still qualify but only if you act now. Press one now to lock in your benefits. Ignore this, you lose everything.  No appeals, no second chances, no safety net. This is not a drill, this is not a joke, this is your last shot to keep what’s yours before Trump’s revenge tour wipes it off the map.  Press one now to talk to a specialist. Press one before it’s too late or press two if you want to let Trump and Vance take everything away from you. To opt out call (833) 867-3774, but if you actually care about your benefits press one right now.

This call campaign is problematic because of a high volume of calls, appearing to exceed fifty million in March, originating from hundreds of thousands of different numbers. The calls do not clearly identify the company calling.  Further, based on consumer feedback, they appear to target people who never contacted the company or requested a call.

The Source of This Data

These data points are provided by YouMail, a free call protection app for mobile phones. YouMail won the American Business Awards’ Gold Stevie Award for Technical Innovation of the Year, and the YouMail app was named the nation’s best robocall-blocking solution in a competition organized by Geoffrey Fowler of the Washington Post.

YouMail blocks unwanted robocallers by making sure the user’s phone doesn’t ring, and then plays an out-of-service message that leads them to think they dialed an invalid number. YouMail identifies problematic numbers and robocalls using a combination of its recently patented audio fingerprinting technology, call patterns, and consumer feedback.

YouMail provides the YouMail Robocall Index to estimate robocall volume across the country and for specific area codes every month. This estimate is formed by extrapolating from the behavior of the billions of calls YouMail has handled for its users, and these statistics are regularly cited by the FCC as a definitive source for national data trends.
