Over the past five years, annual robocall volume has consistently remained between approximately 50 billion and 55 billion, according to the YouMail Robocall Index. Robocall volume for 2025 totaled 52.5 billion, down a little over 1% from the 2024 total of 52.8 billion.
December’s 4.1 billion robocalls were up 6.4% from November but down 5.7% from December 2024. YouMail noted that robocalls increased in November and December 2025 after reaching a multi-year low in October. In December, consumers received an average of 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. However, the December results were 15.6% higher than during the comparable year-ago period.
All robocall categories increased during December. Notifications rose nearly 11%, payment reminders increased 2%, and unwanted telemarketing and scam calls climbed more than 4%.
Robocall volume
“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,” Alex Quilici, YouMail CEO, said in a prepared statement. “Overall robocall volume in 2025 remained consistent with recent years and even saw periods of meaningful decline.”
Telemarketing and scam calls alone accounted for more than 2.3 billion robocalls in December, accounting for more than half (56%) of all robocalls placed. In November, the most annoying robocalls involved various types of loans, particularly pre-approved debt relief offers, following the trend established earlier in the year, according to YouMail.
These pre-approved loan campaigns result in hundreds of millions of robocalls every month, the report found. Blocking a number doesn’t help much, as each campaign originates from thousands of different numbers, including many toll-free numbers. Often, few calls are made from each number.
