IRVINE, Calif., Jan. 8, 2026 /PRNewswire/ -- U.S. consumers received just under 4.1 billion robocalls in December 2025, bringing the yearly total to 52.5 billion, according to the Robocall Index from YouMail, the robocall protection app that tracks call data. December's total marks a 6.4% increase from November 2025 but a 5.7% decrease from December 2024. 2025 closed with two consecutive months of rising robocall volume after reaching a multi-year low in October 2025.
December averaged 140.6 million robocalls/day and 1,627 robocalls/second, down 7.8% from November's 157.6 million robocalls/day and 1,824 robocalls/second. Unfortunately, this was a 15.6% increase on a year-over-year basis from December 2024.
"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."
These latest figures are provided by YouMail, a totally free app that protects consumers from unwanted or dangerous calls, texts, and voicemails. YouMail calculates national robocall trends by extrapolating from the robocall traffic attempting to get through to YouMail's millions of active users.

2025 Robocall Volume
YouMail reports robocallers targeted U.S. consumers with 52.5 billion calls throughout 2025, a decline of less than 1% from the 52.8 billion robocalls recorded in 2024. Over the past five years, annual robocall volume has consistently remained between approximately 50 billion and 55 billion robocalls.
During that same time period, we have seen the average number of robocalls per day in the range of 120 million to 160 million each month, with the past six months falling into a narrower band of 120 million to 140 million calls per day range.
For 2025 overall, notifications fell more than 13%, and payment reminders dropped nearly 20%. In contrast, unwanted telemarketing and scam calls surged 15.4%, making up 57% of all robocalls, up from 49% in the prior year.
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.
