Consistent with other analyses, Hiya’s report found that the number of robo-calls is on the rise. Roughly 26.3 billion robo-calls were placed to U.S. phone numbers last year, Hiya said, up from 18 billion in 2017. One report last year projected that as many as half of all cellphone calls in 2019 could be spam.
While many businesses have legitimate purposes for using robo-calls — think package delivery services, home maintenance technicians and banks — unwanted robo-calls represent a growing challenge for regulators and telecom companies.
In its analysis of a month’s worth of calling data, Hiya found that each of its app users reported an average of 10 unwanted robo-calls. Many more incoming calls, about 60 on average, were from unrecognized numbers or numbers not linked to a person in the recipient’s address book.
What’s more, only about half of all cellphone calls are being answered at all, according to Hiya, whose systems integrate with lists of known and suspected spam numbers maintained by the Federal Communications Commission and the Federal Trade Commission.
“As our phones continue to be inundated by robo-calls, many people no longer want to pick up the phone at all,” said Hiya chief executive Alex Algard. But, Algard added, that can also lead to missing important calls from doctor’s offices, banks, schools and other institutions.
Federal regulators have moved to crack down on unwanted and spam communications, levying massive fines against those who have illicitly harassed people on the national do-not-call telemarketing list and adopting rules facilitating the rollout of new technologies to combat unwanted calls.
This month, T-Mobile said it would soon begin activating a technical protocol known as SHAKEN/STIR, a type of caller authentication that follows the same principles as website encryption. Other carriers including AT&T, Verizon and Sprint have also committed to implementing the feature. Endorsed by the FCC, the new protocol is part of an industry-wide push to limit the effects of caller-ID spoofing, which is when a spammer poses as a caller from a nearby area code in an effort to trick recipients into picking up the phone.
The FCC received 52,000 consumer complaints about caller-ID spoofing alone in 2018, the agency has said.
