What to do if your number shows as Potential Spam on another Carrier
Why would my calls be blocked or labeled as “Spam Likely” or “Potential Fraud”?
If your number is showing on another Carrier as Potential Spam, “Spam Likely”, or “Potential Fraud”, or your calls are being blocked by an otherwise reachable number, it could be that Carrier has deemed your number as a spam risk. In today’s digital age, telecom providers and mobile carriers use increasingly sophisticated tools to protect users from unwanted or harmful calls. If your calls are being blocked or flagged as “Spam Likely” or “Potential Fraud,” it could be due to a variety of reasons—some of which may be unintentional or fixable. When the analytics indicate potentially unwanted traffic, carriers may respond by blocking calls or, in the case of major US mobile carriers, inserting “Spam Likely”, “Telemarketer”, “Fraud Likely”, or other similar labels to display on the handset..
Please note Clearly IP cannot directly influence how the caller information is displayed at the destination.
Here’s a breakdown of the common causes and how to address them.
1. Your Number Resembles a Known Spam Pattern
Robocallers often “spoof” numbers to make them look local or legitimate. If your number shares a prefix or format similar to those previously used in scams, it may get caught in spam filters—even if your calls are legitimate.
2. High Call Volume or Short Call Durations
If your number makes hundreds or thousands of calls daily, especially if many are unanswered or last only a few seconds, carriers may flag your number as suspicious. This often affects businesses using auto-dialers or call centers.
3. Consumer Complaints
If recipients mark your number as spam or report it to their carrier or third-party apps like Hiya, Truecaller, or RoboKiller, this data can contribute to your number being labeled as spam or fraud.
4. Caller ID and Number Spoofing
If someone is spoofing your number (making calls that appear to come from you), your legitimate calls may be mislabeled. Unfortunately, this is common, and the real owner of the number often isn’t aware it’s happening until their calls start getting blocked.
5. Lack of Caller ID or Incomplete Information
Calls without a name, company ID, or other identifying information are more likely to be marked as suspicious. Consumers and networks tend to trust clearly labeled calls more.
6. STIR/SHAKEN Non-Compliance
STIR/SHAKEN is a framework designed to reduce robocalls and number spoofing in the U.S.
Why are my calls showing as “Spam Likely” or similar, if I already have Caller ID Name (CNAM) set on my outbound numbers?
Having a Caller ID Name is a great start! Registering CNAM can help identify your calls and prevent them from being mistakenly perceived as spam by call recipients, lowering the chances of mislabeling.—but it’s only one piece of a larger system.
Spam labeling is managed by third-party analytics companies (like Hiya, First Orion, TNS) and mobile carriers, not by the CNAM database. These systems use algorithms that analyze calling patterns, call volumes, consumer feedback, and more.
Even with accurate caller ID, your number can still be flagged due to call behavior:
High Call Volume: Making a large number of outbound calls, particularly quickly.
Low Engagement: Many unanswered or very brief calls.
Spam Reports: Consumers marking your number as spam.
Negative Number Block History: Your number belonging to a range with a history of misuse.
Impact of Spoofing and Shared Reputation: Your number might be incorrectly flagged if it has been spoofed by scammers or if its prefix is similar to those used in spam campaigns, leading to a negative association.
What can I do to prevent my legitimate calls from being mislabeled as “Spam” or “Scam”? And what can I do if my legitimate calls have already been labeled as “Spam Likely” or similar?
Monitor and Improve Call Patterns
Avoid rapid, repeated calling or leaving too-short voicemails. Space out outbound calls and ensure you're calling with consent to reduce negative marks.
