U.S. Phones Received Almost 4 Billion Robocalls in May, Says YouMail Robocall Index

May Robocalls Nearly Flat with April Volume; On a Pace for 48 Billion Total Calls This Year

IRVINE, Calif., June 8, 2022 /PRNewswire/ -- Americans received just under 4 billion robocalls in May, tracking with the average monthly volume so far this year and keeping 2022 on pace to hit 48 billion robocalls for the full year. This monthly call volume marked a 1.2% decrease from April. Because May has one more day than April, robocalls were actually down 3.2% on a daily basis, which is not surprising given the Memorial Day holiday. Specifically, May averaged 127.2 million calls/day and 1,472 calls/second, compared to 131.4 million calls/day and 1,521 calls/second in April. This robocall volume was also almost identical to the volume one year ago, in May 2021.

"Robocall volumes are fairly stable so far this year, which is good news," said YouMail CEO Alex Quilici. "However, we see signs that robocallers are changing their techniques and we would not be surprised to see a steady increase in volume going forward."

These latest 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.

Most Unwanted Robocall in May

May's most unwanted robocall campaign is estimated to have been the source of tens of millions of robocalls from tens of thousands of different numbers. As in this example, the callers appear to be  selling health insurance marketplace policies and appear to be violating a variety of telemarketing regulations, as they do not identify themselves, do not provide a call back number, and appear to be calling people who did not give prior consent. Here is the call transcript:

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.
