More Than 3.8 Billion Robocalls in September Mark 4% Monthly Increase, Says YouMail Robocall Index

IRVINE, Calif., Oct. 7, 2020 /PRNewswire/ -- Americans received just over 3.8 billion robocalls in September, an approximately 4% increase from August. In September, robocalls averaged 126.9 million calls/day or roughly 1,469 calls/second, up 7% from 118.3 million calls/day and 1,370 calls/second in August. There have been just over 33.9 billion robocalls so far in the first 9 months of the year, a pace that indicates a projected yearly total of around 50 billion robocalls, down from almost 58.5 billion robocalls last year.

These latest monthly figures come from YouMail, a totally free robocall blocking app and call protection service for mobile phones.

"Robocalls continue to grow more slowly than we expected as the world reopens," said YouMail CEO Alex Quilici. "The issue is that if the rate of calls per day keeps growing at 5% to 10% per month, robocalls will become a more and more noticeable problem throughout the rest of the year."

Robocall Categories Were Similar in September

The breakdown of categories was similar in September compared to August. Scams and telemarketing together continue to be a big headache, with roughly 2.3 billion calls between them and comprising roughly 60% of the month's total robocall volume.

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.
