2018 TNS Robocall Report: One-Third of Calls Are High Risk or Nuisance


One-third of all calls to wireless and wireline subscribers are now considered to be high risk (scam/fraudulent) or nuisance, according to the Transaction Network Services (TNS) 2018 Robocall Investigation Report. The report also finds that Monday sees the heaviest volume of robocalls, while Friday is the lightest day.

The 2018 Robocall Investigation Report draws from over 1 billion daily call events across hundreds of carriers and integrates a vast amount of factual evidence from TNS network traffic over the last three years. The data analyzed for this report is unique to the telecom industry, offering an objective, first-hand view of robocalling, spamming and spoofing.

High risk (scam/fraudulent) and nuisance robocalls are up 15 percent the first eight months of 2018 according to the report, challenging policymakers as well as carriers and other industry participants to identify strategies and solutions able to protect consumers and businesses.

Additional key findings from the TNS Robocall Investigation Report include:

  • Robocall scammers give consumers a case of the Mondays. Nearly one-quarter (24%) of all high risk and nuisance robocalls originate on Mondays. While most businesses do not typically call customers on the weekend, Saturday (17%) and Sunday (19%) followed as the next two heaviest robocall volume days. Robocall traffic declines as the week progresses, with Friday (7%) being the lightest day.
  • Neighbor spoofing emerges as a preferred tactic. Robocall scammers believe users are more likely to answer the phone if Caller ID shows a familiar number.
  • VoIP numbers used heavily by robocallers. 50% of the high risk/nuisance calls originate from VoIP numbers.
  • Robocallers doubling down on invalid/unallocated numbers. The use of invalid and unallocated numbers (such as those with area codes that dont exist) continues to rise, doubling over the first eight months of 2018.
  • Robocall user feedback has nearly doubled. Growing consumer frustration with robocalls has translated into users more proactively providing crowdsourced feedback to carriers. Subscribers report 57% of robocalls as spam, 22% as scam-fraud, 14% as telemarketers, and 7% as other.

The reports data reveals an important story: consumers and businesses are increasingly the target of high risk robocalls while scammers continue to turn to neighbor spoofing and other new tactics to stay one step ahead of robocall blocking and detection solutions, said Bill Versen, Chief Product Officer, TNS. The good news is that consumers are more proactive in reporting negative robocalls, and carriers are tapping this invaluable feedback as well as big data from across their networks to identify robocallers in real-time and better protect subscribers.
