Mislabeled Numbers

Spam, Scam & Fraud

If you have ever received a call on your cell phone labeled ‘Fraud,’ ‘Scam,’ or ‘Spam,’ you’ve experienced call labeling technologies in action
Call labeling technologies introduced in 2017 aimed to address the problem of a growing number of illegal calls and robocalls defrauding consumers.
These technologies assign a reputation to calls, displaying labels such as ‘Scam,’ ‘Fraud’ or ‘Spam’ on an incoming call screen.
Calls categorized as Scam or Fraud can also be blocked at the network level, based on this reputational scoring.

Call labeling and robocall mitigation history

State of the Industry

Spam Labeling
Call blocking and labeling technologies, or reasonable analytics, are introduced to address the problem of a growing number of illegal calls defrauding consumers.

These technologies assign a reputation to calls, displaying labels such as ‘Scam,’ ‘Fraud’ or ‘Spam’ on an incoming call screen.

Numeracle gets involved as the voice of the enterprise, protecting legal and wanted communications by remediating call blocking and labeling issues through our Verified Identity and Number Reputation solutions.
December 2020

Illegal robocall traffic continues to grow despite call blocking and labeling technologies and begins to harm legal communications who are being mislabeled.

The FCC publishes the TRACED Act to require the implementation of an identity authentication framework (STIR/SHAKEN) to reduce the amount of illegal robocalls by verifying the identity of the caller and prevent call spoofing.

But, the gap in STIR/SHAKEN does not weigh in, in any way, on a call's reputation, with analytics still impacting number reputation, regardless of implementation.
June - September 2021
FCC mandates two deadlines to implement the STIR/SHAKEN caller ID authentication framework across the carrier network, tracking progress or intent to file in the Robocall Mitigation Database.
The second deadline was a deadline to hereafter mark the beginning of widespread call blocking.
So STIR/SHAKEN won't solve your Spam Labeling issues...
The purpose of STIR/SHAKEN is to reduce the number of illegally spoofed calls, but STIR/SHAKEN does not weigh in on a call's reputation.

STIR/SHAKEN is utilized to verify the identity of the calling party and its authorization to deliver traffic across the phone numbers displayed.

Now that the authentication framework is being implemented, reputational and event-based analytics will still be utilized across the wireless carriers to guide decisions on call labeling.

Understanding Call Blocking and Labeling
When you get a phone call and see labels like these, you’re experiencing call labeling technologies in action
The algorithms driving reputational analytics will vary across mobile networks, but overall, risk ratings are the raw perception data driving the presentation of the call labels themselves.
Higher ‘risk’ ratings drive more severe ‘warning’ language presented to the consumer in the form of a call label but can also result in calls being blocked at the network level.

These solutions often provide updates to phone numbers that become labeled across various sources but can’t provide a path to correct reputation that’s been identified as negative.
Enterprises must review the monitoring data and them make choices on what to do about the numbers that have been flagged, often disrupting the flow of day to day operations.
the use case
When numbers become labeled, monitoring solution providers often recommend numbers are swapped, rested, replaced, or dialing strategies on these numbers adjusted.
Unprotected numbers can become labeled almost as quickly as they go into circulation.
The Difficulty
  • Number swapping is an endless cycle to get around labeling, losing time & resources in the perpetual revolving door of negative reputation
  • New numbers can inherit reputational ‘baggage’ from whoever was using them last and doesn't guarantee solving a call's reputation
