U.S. consumers received nearly 4.1 billion robocalls in December 2025, pushing the annual total to 52.5 billion, according to YouMail’s Robocall Index. The December figure represents a 6.4% increase over November 2025 but a 5.7% decline compared with December 2024. Overall, 2025 ended with back-to-back monthly increases in robocall volume following a multi-year low reached in October 2025.
December saw an average robocall volume of 140.6 million calls per day, or roughly 1,627 robocalls per second, representing a 7.8% decline from November’s average volume of 157.6 million robocalls per day and 1,824 per second. Despite the month-over-month drop in volume, December’s robocall activity was still up 15.6% compared with December 2024 on a year-over-year basis.
“Despite government and industry efforts to reduce robocalls, total volume continues to exceed 50 billion calls per year. And we continue to see nearly 30 billion unwanted telemarketing and scam calls annually, a number that continues to grow,” said YouMail CEO Alex Quilici. “Consumers need apps like YouMail to protect themselves now. That said, overall robocall volume in 2025 remained consistent with recent years, and even saw periods of meaningful decline.”

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.
