Approximately 4.1 Billion Robocalls Received in November, Says YouMail Robocall Index

American Consumers and Businesses on Track to Top 50 Billion Robocalls This Year

Americans received just under 4.1 billion robocalls in November, essentially the same number of calls as in October. However, in November, robocalls averaged 137.4 million calls/day and 1,590 calls/second, up slightly from October, when robocalls averaged 132.0 million calls/day and 1,528 calls/second.

Americans have received 46.9 billion robocalls so far this year, with the country continuing on a pace to hit roughly 51 billion robocalls for the full year. However, since STIR/SHAKEN and new federal robocall mitigation rules took effect on June 30th, overall robocalls have continued to be down about 8% per month on average.

These latest monthly figures are provided by YouMail, a totally free robocall blocking app and call protection service for mobile phones. These figures are determined by extrapolating from the robocall traffic attempting to get through to YouMail’s millions of active users.

“The good news is that monthly robocalls continue to be on a lower plateau since the STIR/SHAKEN rollout on June 30th,” said YouMail CEO Alex Quilici. “The bad news is that we’re still going to see over 50 billion robocalls this year, despite being meaningfully below our past pre-2020 peaks.”

These data points are provided by YouMail, a free call protection app for mobile phones. YouMail recently 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.
