U.S. Consumers Received Over 4.8 Billion Robocalls in May 2025, According to YouMail Robocall Index

Monthly Robocall Volume Over 7% Year Over Year

IRVINE, Calif., June 6, 2025 /PRNewswire/ -- U.S. consumers received just over 4.8 billion robocalls in May, according to YouMail's latest Robocall Index. While this represents a 2.5% decrease from April, a welcome decline after April's robocall volume reached its highest number since August of 2023, it also marks a 7.3% increase compared to May 2024. Additionally, the first five months of 2025 have seen 23.8 billion robocalls, which is an approximately 11% increase over the same period in 2024.

May averaged 165 million robocalls/day and 1,803 robocalls/second, down 5.6% from April's average of 165 million robocalls/day and 1,910 robocalls/second.

"It's nice to get a breather from 2025's trend of higher robocall volume," said YouMail CEO Alex Quilici. "However, it's disappointing that the volume continues at a high level, and consumers still need to protect themselves from these annoying and sometimes dangerous calls."

These latest figures are provided by YouMail, a totally free app to protect consumers from unwanted or dangerous calls, texts, and voicemails. The data is extrapolated from robocall traffic attempting to reach YouMail's millions of active users.

Scam Calls Rose More Than 10% in May

The good news from May is that most categories of robocalls dropped during the month. The bad news: scam calls continued to rise. With more than 690 million scam calls placed in May, YouMail measured an increase of more than 10% compared to April.  

As a result, May saw roughly 2.7 billion scam and telemarketing robocalls, nearly identical to April's total. These likely unwanted calls now account for roughly 55% of all robocalls each month.

May 2025's Most Annoying Robocalling Campaign

The most problematic robocall campaign in May involved calls urging recipients to pay for increased visibility in Google search results. These calls, such as those from this number, featured messages like this:

Our records show your listing is not verified or missing important information keeping your customers from finding you. Press 1 now so we can verify your Google My Business listing. If you are the business owner, press 1 now. If your account is not verified, customers searching for your services on Google will not find your listing. Press 1 now to verify your listing. Press 2 or call (866) 202-3044 and EMG listings will remove you from this list.

This call campaign is problematic due to its high call volume, which YouMail determined to be in the tens of millions in May. The calls originated from tens of thousands of different numbers, and deployed several variants of this basic message. Another issue is the calls do not identify themselves at the beginning, and based on consumer feedback, they target people who never contacted the company or requested a call. Some targets don't even own a business. Further, the campaign appears to use a different number each time it contacts a particular user. These calls imply that payment is required to increase visibility in Google search results are intended to get people to pay for search-related services by implying these services are necessary for the user's business to appear in searches, despite Google providing these services for free
