How to remove potential spam from Caller ID?

Why Your Legitimate Calls Are Getting Labeled 'Spam Likely'

Your phone rings. The caller is a real prospect, expecting your call — but the screen says "Spam Likely," and the call dies unanswered. For businesses running compliant outbound programs, this scenario is now the norm, not the exception.

The numbers explain why. Robocall volume has climbed 20% year-over-year to 2.56 billion scam and telemarketing calls per month through September 2025, with Truecaller estimating the increase as high as 33%. Roughly 57% of all robocalls this year are scam or telemarketing calls, and 2025 volume has already surpassed the pre-2019 average recorded before federal robocall legislation took effect.

Carriers have responded with aggressive filtering. The FCC calls illegal robocalls its top consumer protection priority and has empowered phone companies to block suspected illegal calls before they reach a consumer's phone. Some carriers even block numbers not on a customer's contact list when the customer opts in. The filtering is blunt, and legitimate businesses get caught in the net.

Consumers, meanwhile, have stopped taking chances. Pew Research Center data shows 31% of American adults receive at least one scam call daily, and 21% get several per day. Average losses hit $3,690 for scam call victims in the first half of 2025. With one in four adults having already been tricked into handing over personal information, screening unknown numbers is rational behavior — even when your call is the one they asked for.

The technical backbone meant to fix this is unevenly deployed. Only 44% of U.S. phone companies have fully installed STIR/SHAKEN caller ID authentication as of September 2025 — down from 47% in 2024. When your provider's authentication is incomplete, carriers downstream treat your calls with more suspicion, and "Spam Likely" labels follow.

The damage compounds quickly:

• Answer rates collapse — consumers won't pick up a flagged number, no matter how warm the lead.
• Speed-to-lead advantage evaporates — a follow-up call inside five minutes means nothing if it lands labeled as spam.
• Reputation spreads across carriers and third-party blocking apps, making the label self-reinforcing.
• Compliant callers get grouped with bad actors because filtering algorithms judge patterns, not intent.

This is why disciplined contact hygiene matters before dialing. Every list GrowthPros delivers is DNC-scrubbed and carries a consent record — disclosure text, timestamp, IP address — precisely because clean, documented calling practices are the first line of defense against spam perception. Nearly half of consumers say they're more likely to answer calls from brands they recognize, which means the businesses that verify their numbers and clean up their Caller ID aren't just avoiding the label — they're winning the pickup.

STIR/SHAKEN: The Technical Foundation That Determines Whether Your Calls Get Through

If your calls are getting flagged as "Spam Likely," the first place to look isn't your dialing behavior — it's whether your phone provider has actually implemented the caller ID authentication standard the FCC mandates. Without it, your legitimate calls are swimming in the same unverified pool as the 2.56 billion scam and telemarketing calls hitting U.S. phones every month, a volume that jumped 20% year-over-year through September 2025.

STIR/SHAKEN is the FCC's answer to caller ID spoofing. It works by digitally signing caller ID information at the originating carrier and validating it across IP networks before the call reaches the recipient, per the FCC's call authentication framework. When your call carries a valid signature, receiving carriers can cryptographically confirm the number on screen actually belongs to the caller. When it doesn't, carriers treat the call with suspicion — blocking it outright or slapping a spam label on it.

Here's the problem: compliance is slipping. Only 44% of U.S. phone companies had fully implemented STIR/SHAKEN as of September 28, 2025 — down from 47% in 2024, according to a U.S. PIRG analysis of FCC data. Among 33 major providers reviewed, 18 reported complete implementation, 12 partial, and 3 none at all. Some providers, including Breezeline and Vyve Broadband, actually regressed from "complete" to "no implementation."

That matters for your business directly. Every phone company must file its status in the FCC Robocall Mitigation Database, and providers that fail to fully authenticate are required to mitigate robocalls on their networks — or face traffic being blocked by other carriers. If your provider is in the partial or non-compliant column, your outbound calls inherit that distrust.

So what should you demand from your telecom provider before signing or renewing?

• Written confirmation of full STIR/SHAKEN implementation, with their current filing in the FCC Robocall Mitigation Database to back it up
• A commitment to respond to traceback requests within 24 hours, the standard non-compliant providers must meet
• Support for attestation levels that verify your business identity, not just your phone number
• A documented process for disputing spam labels on your numbers

This is also why the plumbing behind your lead flow matters. At GrowthPros, every lead we deliver gets follow-up inside a five-minute window — and that speed is worthless if the call never rings through with a trusted signature. Your caller ID reputation and your compliance practices (DNC scrubbing, consent records, opt-out honoring) work together to keep answer rates high.

If your number is already being mislabeled, the FCC maintains a complaint pathway for numbers being spoofed, blocked, or mislabeled. The agency won't resolve your individual case, but complaints feed enforcement under the Truth in Caller ID Act. Fix the technical foundation first, though — authentication is the gate that determines whether everything else even gets a chance.

Branded Caller ID and Verified Numbers: Making Your Calls Visibly Legitimate

Your caller ID is the first thing a prospect sees — and if it says "Spam Likely," your pitch is dead before anyone picks up. Verification and branding exist precisely to solve that first-impression problem.

Verified phone numbers work by confirming that a number genuinely belongs to the business using it. As Retell AI explains, this makes it far harder for scammers to spoof legitimate numbers, because the carrier ecosystem has already authenticated the link between the number and the company name. In a year when robocall volume climbed 20% to 2.56 billion scam and telemarketing calls per month, that authentication is what separates you from the noise.

Branded caller ID takes verification a step further by displaying your business name and logo on the recipient's screen before they answer. The payoff is measurable: nearly half of consumers are more likely to answer calls from brands they recognize, and 83% of customers report greater trust in companies that prioritize secure communication.

Before you set it up, know the carrier constraints on your display name:

• T-Mobile and AT&T support up to 32 characters for branded caller ID
• Verizon supports only up to 15 characters — plan your name accordingly
• Verification requires submitting business information through a platform that reviews and approves your data, which helps you avoid the "Spam Likely" label

Character limits matter more than businesses expect. A legal name like "Apex Home Services of Greater Phoenix" won't survive Verizon's 15-character cap, so decide early what truncated version customers will actually see.

The same logic applies to every outbound touchpoint. At GrowthPros, every lead we deliver — whether freshly sourced or reactivated from a dormant list — gets AI voice, SMS, and email follow-up within a five-minute window, and none of it works if the call itself looks fraudulent. A verified, branded number is what makes speed-to-lead worth having.

Verification also protects you from the other side of the problem: spoofing. If your number is being impersonated, the FCC provides a formal complaint pathway for numbers that are spoofed, blocked, or mislabeled, feeding enforcement under the Truth in Caller ID Act. Pair that with STIR/SHAKEN authentication from your provider, and your identity becomes genuinely hard to fake.

The businesses that win the phone channel are the ones that look legitimate before the first ring ends. Verify your numbers, brand your display, and keep your name short enough to survive every carrier.

Clean-Up and Compliance: Fixing Mislabels and Preventing New Ones

Even with proper technical safeguards in place, legitimate business numbers can still get flagged as spam due to mislabeling or spoofing attempts. When this happens, businesses need a clear path to remediate the issue and prevent recurrence. The FCC provides formal complaint pathways specifically designed for numbers being spoofed, blocked, or mislabeled—allowing legitimate callers to reclaim their Caller ID reputation. Consumers and businesses can report these issues directly to the FCC, which uses the data to identify patterns and pursue enforcement against bad actors under the Telephone Consumer Protection Act or Truth in Caller ID Act.

To initiate the remediation process, businesses should document instances where their number is incorrectly labeled as spam, blocked, or shows signs of spoofing. These records should include timestamps, caller ID displays, recipient feedback, and any evidence of unauthorized use. Once documented, complaints can be filed through donotcall.gov or by calling 1-888-382-1222. While the FCC does not resolve individual cases, aggregated complaints help inform policy decisions and trigger investigations that can lead to fines or injunctions against spoofers targeting legitimate business numbers.

Preventing future flags begins with proactive compliance practices that align with both regulatory expectations and consumer trust. GrowthPros ensures every lead undergoes DNC scrubbing before any outbound contact, removing numbers on the National Do Not Call Registry to avoid violations that trigger spam labeling. Opt-out requests are honored immediately and permanently across all channels—voice, SMS, and email—with suppression maintained indefinitely in client systems. Consent records are meticulously preserved for each lead, including disclosure text, timestamp, IP address, and the named contacting party, satisfying FCC one-to-one consent requirements. For prerecorded calls, strict identification protocols are followed: the caller’s name, number, and business name are stated at the outset, building transparency and reducing the likelihood of being marked as spam. Together, these practices form a compliance-first approach that not only avoids legal risk but also strengthens Caller ID reputation over time. Only 44% of U.S. phone companies had fully installed STIR/SHAKEN caller ID authentication as of Sept. 28, 2025, down from 47% in 2024, underscoring why businesses must take ownership of their own compliance rather than relying solely on carriers. Nearly half of consumers are more likely to answer calls from brands they recognize, making verified identity a critical component of answer rate improvement and spam perception reduction.

When Your Lead-Follow-Up Calls Are the Ones Getting Flagged

You nailed the five-minute follow-up window. The lead is hot, the consent record is clean, and your team is ready to call — but the prospect's screen lights up with "Spam Likely" and the opportunity evaporates before the first ring. Contacting a lead within five minutes makes contact roughly 100x more likely than at thirty minutes, yet that advantage disappears when carrier algorithms flag your number before a human even sees it.

The problem isn't your outreach — it's the trust layer between your dialer and their phone. Robocall volume hit 2.56 billion scam and telemarketing calls per month through September 2025, a 20% year-over-year increase that has carriers aggressively filtering anything that looks suspicious. Only 44% of U.S. phone companies have fully installed mandated STIR/SHAKEN caller ID authentication as of late 2025, down from 47% the prior year, leaving gaps that legitimate calls fall through. Meanwhile, nearly half of consumers are more likely to answer calls from brands they recognize, which means visual verification on the handset directly impacts answer rates.

GrowthPros builds that trust into every lead before the first dial:

• DNC-scrubbed lists and consent records attached to every lead — disclosure text, timestamp, IP address, and the named contacting party
• AI voice, SMS, and email follow-up inside five minutes so the first touch lands as a recognized, expected contact
• Leads delivered into your CRM with the full consent trail intact, ready for compliant outreach

When your outbound calls carry verified identity and the prospect already received a branded SMS or email from you minutes ago, the "Spam Likely" label loses its power. The FCC complaint pathway exists for numbers being spoofed, blocked, or mislabeled, but prevention beats remediation every time — especially when your speed-to-lead window is measured in minutes, not hours.
