US phones received nearly 4.4 billion robocalls in March, according to YouMail Robocall Index


Mars robotic call volume returned to pre-shake/shake levels

IRVINE, Calif., April 6, 2022 /PRNewswire/ — In March, Americans received nearly 4.4 billion robocalls, setting 2022 on pace to reach 48 billion robocalls for the full year. This monthly call volume marked a 16.1% increase over February. However, since February is three days less than March, robocalls actually only increased by 4.8% on a daily basis. More specifically, the month of March recorded an average of 140.8 million calls/day and 1,630 calls/second, compared to 134.2 million calls/day and 1,554 calls/second in February.

March saw roughly the same call volume as last June with 4.4 billion calls, meaning robocall volumes are essentially back to where they were in spring 2021, before rolling out new Stir/Shaken rules for call authentication. However, call volumes were still down significantly from the nearly 5 billion recorded about a year ago, in March 2021and are well below the peak of 5.7 billion robocalls/month of October 2019.

“It’s incredibly disappointing but not unexpected to see robocall volumes return to where they were before the Stir/Shaken rollout,” said YouMail’s CEO. Alex Quilici. “Robocalls continue to be a stubbornly difficult problem, although the good news is that they’re less of a problem than they were a few years ago.”

These last 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 robocall traffic attempting to reach YouMail’s millions of active users.

The most unwanted robocalls in March

The most unwanted robocall campaign of March is estimated to have caused tens of millions of robocalls from around 6,000 different numbers. The callers claim to reach people eligible for “ObamaCare” health insurance policies. As in this examplethe callers appear to be violating various telemarketing regulations, at a minimum, as they do not identify themselves, do not provide a callback number, and further appear to be calling people who have not given prior consent.

Also, last month loan approval scam robocall continues unabated at a rate of approximately 100 million calls/month.

Spam calls have increased dramatically March 2022

In March, the number of unwanted spam and scam calls increased significantly, from more than 700 million calls for the month to nearly 2.4 billion, representing more than 55% of all robocalls. Specifically, fraudulent calls increased 59% to 1.65 billion and telemarketing calls increased 17% to 0.73 billion. On the other hand, robocalls that are likely more sought after, such as notifications and payment reminders, declined by around 100 million robocalls to just under 2 billion during the month.

YouMail provides the YouMail robocall index to estimate the volume of robocalls across the country and for specific area codes each month.
