35+ Phone spam Statistics for 2017 - 2020

Phone spam is a major problem. So big, in fact, that Americans are collectively fending off over 4 billion spam calls per month. Some researchers suggest that phone spam will make up over 40% of all phone calls in the US from 2019 onward, highlighting just how big of a problem we have on our hands in the States.

I’ve also written about my own spam call problem with eye-opening data visualizations that highlight how the problem is plaguing my own phone. My situation is likely reflective of what many American, Canadian, and UK residents are also experiencing, given the phone spam problem extends beyond just the US and beyond just one man. The problem has grown so large, in fact, that it’s created an entire (and lucrative) market for apps (like Truecaller and Robokiller) that filter out spam calls. Tech companies and governments alike are investing massive amounts of time and resources into solving the problem.

With phone spam receiving increasing amounts of scrutiny, it should come as no surprise that there are key phone spam statistics that highlight the growing problem.

Additional phone spam and scam statistics

Phone spam is an international nuisance that represents just how advanced cybercriminals have become at using telecommunications technology to their own advantage. The significant growth rate of mobile-based phone spam and phone number spoofing also reflects the difficulties governments, telecommunications companies, tech companies, and consumers are all having when it comes to responding to the threat.

The following statistics provide a clear picture of how extensive phone spam is worldwide, and just how much damage and frustration this issue is causing.

  • Over 26 billion robocalls were made to US phones in 2018, representing a 46 percent year-over-year growth. (Source: Hiya)

  • The rise of Enterprise Spoofing may cause a 20 percent reduction in neighbor spoofing as scam callers switch tactics.  (Source: FirstOrion)

No end to phone spam in sight

Currently, available data suggests one troubling conclusion: there is no clear end in sight for the world’s growing phone-spam problem. As spammers quickly adapt to more discreet and harder-to-stop methods, telecommunications companies and governments have struggled to address the issue. According to Truecaller’s Director of Communications, Kim Fai Kok, “By just looking at the trends and statistics, we do not see spam calls stopping any time soon.”
