Total Robocalls Decrease by 3% in the First Month of STIR/SHAKEN Release

FCC's new anti caller-ID spoofing framework helps to slow down phone scam growth in its first 30 days

NEW YORK, Aug. 6, 2021 /PRNewswire/ -- RoboKiller, the app that eliminates 99% of spam calls and text messages, reveals Americans received an estimated 5.74 billion spam calls in July 2021—a 3% decrease from June. Spam text volume also increased to 7.1 billion spam texts  for July, a 5% increase from June.

New Anti-Spoofing Technology is Helping Fight Against Spam Calls

As previously predicted by RoboKiller, July's 3% decrease in total robocalls reflects a successful first month of the FCC's new anti-caller ID spoofing framework, STIR/SHAKEN, with RoboKiller also observing a 5% decrease in the number of spam calls that use caller ID spoofing from June to July 2021. This means that, on a national level, there were 145 million fewer spoofed spam calls in July than in previous months of 2021.

Decreases in spoofed spam calls in July inform our positive outlook on the future of STIR/SHAKEN technology. However, there is still a lot of work to be done beyond the recent June 30th deadline in order for STIR/SHAKEN to find its legs. This includes:

  1. Voice providers and phone carriers should provide more visibility into how they are utilizing STIR/SHAKEN data to inform decisions about verifying caller IDs and allowing phone calls. This data can help supporting players align their STIR/SHAKEN integration with large networks for a more unified approach.

  2. Forgein service providers who process international calls to United States smartphones must begin to lean in and adopt the STIR/SHAKEN technology for it to be effective. International service providers must establish robocall mitigation plans by September 28, 2021. This will help paint a fuller picture of how effective robocall mitigation efforts are, both here and abroad.

RoboKiller expects spoofed spam calls to continue to decrease as a percentage of total spam calls through year's end, from approximately 35% of estimated total monthly spam calls in July to 30% by December 2021. This decrease will likely be driven by continued improvements to, and adoption of, the STIR/SHAKEN framework as it ramps up its impact in the war against robocalls.

For businesses still looking to comply with or enhance their STIR/SHAKEN solutions, RoboKiller Enterprise offers a flexible robocall mitigation program that's effective and hassle-free. To learn more, visit .

Spam Text Trends Indicate Scammers Are Still Focused on Robocalls, But Not For Long

Moderate increases in spam text volume from June to July 2021 likely indicates that scammers are more focused on establishing technological workarounds to the STIR/SHAKEN framework rather than completely pivoting to spam texts in the technology's first month of release. However, Americans shouldn't count spam texts out.

RoboKiller predicts a 3-5% increase in spam texts for the month of August, as more scammers look to offset losses on robocalls and attempt new approaches to steal from Americans over the phone. Americans are on track to receive more than 86 billion spam texts in 2021, a 55% increase from 2020.

Scammers Target West Coast With Insurance Robocall Scams in Response to Natural Disaster

As the landscape becomes more complicated for robocallers to place thousands of illegal calls per day, many scammers are adjusting their approach to focus on quality over quantity. Scammers do this by tailoring their scams to relevant societal events in the United States, as they are more believable to the target.

In July 2021, RoboKiller observed a 25% increase in home and mortgage insurance offer phone scams, likely driven by natural disasters on the West Coast. Scammers often target regional area codes known to be impacted by disasters such as wildfires in an attempt to steal from the most vulnerable. Those impacted by the wildfires can get 30 days of free phone scam protection with RoboKiller by using promo code RELIEF2021.
