"Scam Likely", "Spam Risk", "Potential Spam", "Telemarketer": these labels are added by the mobile carriers, not by the person you are calling. They come from automated reputation systems that score every calling number, and honest businesses get caught by them every day. This guide explains what the label is, why it lands on legitimate numbers, and the steps that actually fix it.
Where the label comes from
Each major US carrier runs call-labeling through an analytics partner. T-Mobile shows "Scam Likely" using First Orion; AT&T shows "Spam Risk" using Hiya; Verizon's Call Filter uses TNS (Transaction Network Services). Canadian carriers use similar systems. Each partner keeps a reputation score for your number based on signals such as how many calls it makes, how short they are, how many people hang up or report it, whether the number is answered when people call it back, and whether the caller identity is verified.
There is no central blacklist. A number can be labeled by one carrier and clean on another, which is why one customer sees "Scam Likely" and the next one sees your name.
Why an honest business number gets flagged
- High call volume with short calls. Many dials, many unanswered or very short calls, looks like a robocaller, even when the calls are legitimate.
- Rotating or brand-new numbers. Switching numbers to "look local" is the classic spammer pattern. A fresh number with no history and a burst of calls scores badly.
- Nobody answers the callback. If people call your number back and reach nothing, the score drops.
- Complaints. A few "report spam" taps from annoyed contacts carry a lot of weight.
- Unverified caller identity. Calls without STIR/SHAKEN attestation (the carrier-to-carrier signature that confirms you are allowed to use the number) are easier to flag.
- Inherited history. A number you just bought may have been used by someone else before you.
How to fix it, step by step
- Register your numbers with the Free Caller Registry. freecallerregistry.com is a free form that sends your business details and numbers to all three analytics partners at once (First Orion, Hiya and TNS). Fill in your legal business name, website, the numbers you call from and what the calls are about. This is the single most useful step.
- Check each partner's own portal. If a label persists on one carrier, submit a correction with that carrier's partner directly: Hiya for AT&T, TNS for Verizon, First Orion for T-Mobile. Each has a business registration or dispute form.
- Call from one consistent business number. Stop rotating numbers. A single local number that you keep for years builds a reputation; a stack of disposable numbers destroys it. Zorino gives each account one local US or Canadian number and shows it on every call.
- Answer your number. Make sure a human or at least a clear voicemail greeting picks up when people call back. Zorino's callbacks make it easy to return the call quickly.
- Spread the volume and lengthen the calls. Keep the dialer at a pace your reps can handle so that answered calls turn into real conversations. A power dialer with answering machine detection (which Zorino is) helps here: voicemail is skipped and reps only take calls where a person answered, so your answered calls are longer and fewer calls end in a hang-up.
- Respect Do Not Call and calling hours. Fewer complaints means a better score. Zorino enforces your internal Do Not Call list on every dial.
- Identify yourself in the first sentence. People who know who is calling are far less likely to report the number.
- Set your caller name (CNAM) where you can. Some carriers display a business name alongside the number when it is registered; ask your provider.
How long does it take?
Registration with the analytics partners usually takes effect within days, not hours. Reputation built from calling behavior takes weeks: expect two to four weeks of consistent, well-answered calling from one number before labels on all carriers settle down. If a number is badly burned and nothing changes after a month, replace it once, register the new one before you start calling, and keep it.
What does not work
- Buying a new number every week. It resets your history to zero each time and matches the spammer pattern.
- Spoofing a different caller ID. It is illegal when used to deceive, and it fails STIR/SHAKEN attestation.
- Calling faster to "make up" for the flagged calls. More short calls make the score worse.

Call from a number people recognize
Zorino includes a local US or Canadian business number in every plan and shows it on every call your team makes. Try the live demo: it dials up to 5 numbers you choose and rings your phone when someone answers. Two minutes, no account, no card.
