SPAM risk caller ID

Your customers might see calls from your number displayed as “SPAM likely” or “SPAM risk” or “SCAM likely” on their caller ID. While each phone carrier keeps a list of numbers they determine to be spam risks based on the history of the number; scam ID technologies might incorrectly mark your number.

What causes the SCAM/SPAM designation

Here are the most obvious reasons for designation:

  1. The volume of Outbound Calls Per Day Per Number
  2. Or, someone flagged a call from your number in that carrier’s app as spam
  3. Or, it could be your system didn’t correctly set the Outbound Caller ID number

What’s the back story

In response to the growing number of scam calls to mobile phones; many carriers have created tools to identify and block scam calls. Unfortunately, these tools aren’t perfect. And sometimes businesses may have their numbers incorrectly marked by scam ID technology, particularly when calling cell numbers.

Each carrier has a feature or app. And it is automatically enabled on mobile devices. So, when someone calls one of these devices, the carrier checks the number against its database of reported scam numbers. If the source matches a reported scam number, directly, the person being called sees a message that says “Scam Likely” alongside standard caller ID. 

However, the Scam Likely Caller ID features will sometimes mark legitimate calls incorrectly; because some people may report your number without answering the phone. If this happens enough, as a result, your number will be marked Scam Likely.
