Questions

What people ask before they run a check

Why does my number show as “Scam Likely”?

The label is applied by the network the person you are calling is on, not by your own carrier — which is why the same number can look fine on one network and flagged on another. It usually comes from call patterns (high volume, short calls, lots of unanswered ones), from customer reports, or from the number having been spoofed or used by a previous owner.

How do I check what my caller ID displays?

Run a free check from this page — no account needed. We query the carriers and the screening apps for your number and show you the displayed name and any label each one returns, with a screenshot.

Is a spam label the same thing as my CNAM?

No, and this trips a lot of people up. Your CNAM is the name registered against your number. A spam label is a separate judgement the screening network adds on top. Fixing one does not fix the other, so it is worth seeing both side by side before you decide what to chase.

How long does it take for a label to clear?

It varies by network and is not instant — expect days to weeks after a remediation request, and only if the behaviour that caused the label has changed too. Re-checking on a schedule is the only way to know it actually moved.

Will a new phone number fix it?

Often not. A fresh number can arrive already carrying a label from whoever had it before, and if the calling pattern that caused the original flag has not changed, the new number tends to pick one up too. Check a number before you start dialling from it.

Do you test SMS as well as calls?

Yes. Send a message to our device and we show the exact text that arrived, how long it took and the route the provider used, across countries and providers — so you can put two routes side by side.

What does a check cost?

Your first checks are free and need no account. After that it is credits — no seats, no monthly minimum, nothing expiring at the end of the quarter.
