El Paso County made more robocall complaints that any other county in the U.S. from 2014-18, according to a study by Comparitech, a technology rating company.
Colorado was second only to Nevada when it came to complaints.
The study analyzed Federal Trade Commission data of caller complaints and found that most complaints are made in the summer months and peak in August. The data also shows that complaints to the FTC grew 165 percent between 2014 and 2017, reaching a peak of 4.5 million before dropping to about 3.8 million in 2018.
Robocalls in Colorado are most likely to be impersonators of friends and family, or about prescriptions. Nationwide, debt-reduction robocalls made up the majority of the 1.7 million robocalls with identifiable topics that were reported.
There isn’t a fail-safe way to prevent robocalls, but registering with the Colorado and National Do Not Call lists is one way people can protect their phones.
