If the people you call see "Spam Likely," "Scam Likely," "Potential Spam," or a similar warning, it means a phone carrier or a call-screening service has scored the number you are calling from as low reputation. This is common during call time. It is usually possible to improve, but the label is controlled by the carriers and screening apps, not by Raise More. This article explains why it happens and the steps that help.
Why carriers label calls "Spam Likely"
The label is not set by Raise More, and it is not set by your carrier alone. The major US carriers, plus third-party call-blocking apps, run analytics engines that score every outbound number. A number gets flagged when one or more signals look like robocall behavior:
The number is new. A recently provisioned number has no calling history, so scoring engines treat it cautiously until it builds a record.
Call patterns look automated. High volume in a short window, many very short calls, or rapid back-to-back dialing all resemble robocalls, even when every call is legitimate.
Recipients reported the calls. When people decline, hang up immediately, or tap "Report Spam," that feedback lowers the number's score.
Caller-ID attestation is low or missing. STIR/SHAKEN is the industry framework that lets the carrier placing a call cryptographically vouch that the call really comes from the number it claims. Attestation has three levels: A (the carrier fully vouches for the number), B (the carrier knows the caller but not the number), and C (the carrier cannot vouch). Higher attestation makes a "Verified" display more likely; low or missing attestation makes a spam label more likely.
The number has no positive reputation on file. Numbers that have not been reported as legitimate to the analytics providers have nothing to offset the default skepticism.
Because each carrier and app runs its own scoring, the same number can show clean on one network and flagged on another. That is expected and does not mean something is broken.
What Raise More tracks for each caller ID
Raise More handles the carrier-compliance setup for your numbers and keeps two status fields current for each caller ID:
STIR/SHAKEN attestation. When a caller ID is registered with the carrier's business profile and a STIR/SHAKEN trust product, outbound calls from it are signed so the receiving carrier can confirm the call genuinely comes from your verified number. In Raise More this shows as the caller ID's SHAKEN/STIR status.
Voice Integrity. This is a separate carrier reputation product (distinct from STIR/SHAKEN) that improves how analytics engines score your number over time. Raise More tracks it as its own status field.
Both fields are synced from the carrier on a schedule, so the Caller IDs page reflects the current state of each number. When both are approved, your calls carry the strongest trust signal available. A number can still pick up a flag from recipient behavior or from being brand new, but full approval gives the best position to avoid a flag and to recover from one.
Raise More cannot directly remove a spam label that a carrier or screening app has already applied. What it can do is make sure your numbers are correctly registered and attested so they present well.
What you can do about it
Confirm your caller ID is fully approved. On the Caller IDs page, check that your number shows SHAKEN/STIR and Voice Integrity as approved before running a heavy call session. If either is not approved, see "When to contact support" below; getting SHAKEN/STIR set up is done with help from the Raise More team.
Register the number for caller-ID reputation. The Free Caller Registry (freecallerregistry.com) lets you report a number as legitimate to the major analytics providers in one place, and lets you dispute an existing spam flag. This is the most effective single step you can take on your own.
Keep your calling patterns natural. Avoid firing off dozens of calls in quick succession. Pace your dialing, leave normal gaps between calls, and aim for real conversations rather than a wall of one- or two-second connects.
Rotate numbers if one is heavily flagged. A number with a damaged reputation can take time to recover. Adding and verifying a second caller ID lets you spread volume and keep calling while the original number's score improves. Remember that a new number also starts with no reputation, so pair rotation with registration and good calling habits.
Ask recipients to save your number. Contacts who have your number saved are less likely to see a spam label, and saving it teaches their carrier that the number is wanted.
When to contact support
Reach out to the Raise More support team if:
A caller ID is stuck showing as not approved, or SHAKEN/STIR or Voice Integrity will not move to approved status. SHAKEN/STIR setup is handled with our team's help, so contact us if you have not received the steps or are stuck partway through.
Your calls are still flagged after the number is fully approved and registered with the Free Caller Registry.
You want help adding or verifying an additional caller ID to rotate volume.
A number that used to display cleanly suddenly started showing "Spam Likely" and you want help diagnosing the cause.
We can check the carrier-side status of your number and advise on the next step.
FAQ
Does Raise More control whether my call shows as "Spam Likely"?
No. The label is applied by carriers and third-party screening apps based on your number's reputation. Raise More registers and attests your numbers through STIR/SHAKEN and Voice Integrity to give them the best trust signal, but the final display decision belongs to each carrier. Raise More cannot remove a flag directly.
How long does it take a flag to clear?
It varies. Registering with the Free Caller Registry and improving your call patterns can help within days, but reputation recovery is gradual. A severe flag can take a few weeks to fade.
Will registering with the Free Caller Registry guarantee clean calls?
No registration guarantees a clean label on every carrier. It significantly improves your odds and lets you dispute existing flags, which is why it is the most effective single step alongside good calling habits.
Should I just buy a new number whenever one gets flagged?
Rotating helps when a number is heavily flagged, but a new number starts with no reputation of its own. Use rotation together with registration and natural calling patterns, not as a substitute for them.
Can recipients still answer a "Spam Likely" call?
Yes. The label is a warning, not a block. Many people still answer, especially if they recognize the area code or are expecting your outreach.
