You change nothing, and suddenly answer rates drop. Often the cause is a label on the recipient's screen: "Spam Likely", "Scam Likely" or "Potential Fraud". These labels come from analytics engines used by mobile carriers and call-blocking apps — and they can be applied to legitimate businesses.
What usually triggers a label
- High volume from one number — hundreds of calls a day from a single caller ID.
- Many very short calls — people hanging up within seconds looks like unwanted calling.
- Low answer rates and many calls to numbers that are not in service.
- Complaints — recipients reporting the number or blocking it.
- Weak caller ID verification — see our STIR/SHAKEN guide.
How to check your numbers
- Call your own numbers from phones on different carriers and see how they display.
- Look up the number on the public registration and remediation portals that analytics providers offer.
- Watch your answer rate per number: a sudden drop on one number is a strong signal.
How to get a label removed
- Register your numbers with your business details through the analytics providers' registration portals (and the free industry registration services available in the US).
- Request a review for numbers already labelled, explaining your business and the purpose of your calls.
- Fix the cause first — otherwise the label comes back.
How to stay clean
- Spread volume across enough numbers so that no single number makes an unusual number of calls per day.
- Do not rotate numbers just to dodge labels — analytics engines look for that too.
- Scrub lists and remove disconnected numbers.
- Honour opt-out requests immediately.
- Make sure your numbers ring back to your business when people return the call.
- Complete Business Verification so your calls carry your verified identity.
Tip: keep a simple sheet of each outbound number, its daily volume and its answer rate. Problems show up there days before anyone complains.
