How to Stop Your New Business Number from Showing Up as "Spam Likely"

You just invested in a brand-new, professional phone number from RingBoost to grow your business. You fire up your phone system, make your first batch of outbound calls, and your connect rate is virtually zero.

When you test it by calling your own cell phone, you see the dreaded label on the screen: "Spam Likely" or "Scam Likely."

It is incredibly frustrating to have your legitimate business communications blocked before you even get to say hello. But do not panic—this is a common hurdle in the modern telecom landscape, and more importantly, it is completely fixable.

Here is your candid, step-by-step guide on why this happens and exactly what you need to do to clear your number's reputation.

Why is My New Number Flagged as Spam?

To fight the war on robocalls, major U.S. carriers (AT&T, Verizon, T-Mobile) rely on third-party analytics engines to score every phone call in real-time. These algorithms are notoriously aggressive and will flag a number for a few common reasons:

• No Trust History: A newly activated number has no recent calling history. If it suddenly starts making dozens of outbound calls, the algorithms automatically assume it is a spam bot.
• Unverified Caller ID: If your telecom provider has not officially authenticated your business identity using modern protocols, carriers will treat your calls with high suspicion.

The 5-Step Guide to Clearing the "Spam" Label

You do not need to throw the number away. Follow these steps to verify your business and get your calls answered.

1. Secure "A-Level" STIR/SHAKEN Attestation

STIR/SHAKEN is an industry-standard framework designed to authenticate caller IDs and stop call spoofing. There are three levels of attestation (A, B, and C).

• The Fix: You need A-Level Attestation, which means your carrier cryptographically signs your calls, confirming they know who you are and that you have the right to use that number. Contact your telecom or VoIP provider and explicitly ask: "Are my numbers registered for STIR/SHAKEN with A-Level Attestation?" If they say no, require them to set it up.

2. Register Your CNAM (Caller ID Name)

If a carrier does not know who is calling, they are more likely to flag it. CNAM registration pushes your actual business name to the caller ID databases.

• The Fix: Have your phone provider register your business name to your new number. When an actual company name (e.g., "Reliance Emergency") pops up instead of an unknown 10-digit number, answer rates go up, and spam complaints go down.

3. Submit to the Free Caller Registry (The Silver Bullet)

The three major analytics companies that power the spam filters for U.S. carriers are Hiya (AT&T), First Orion (T-Mobile), and Transaction Network Services/TNS (Verizon). Fortunately, they teamed up to create a single portal for legitimate businesses.

• The Fix: Go to FreeCallerRegistry.com. Submit your business details, contact information, and the phone numbers you are using for outbound calls. It is free, easy, and usually clears up "Spam Likely" labels across all major networks within 3 to 5 business days.

4. Manually Whitelist with Individual Engines

If a few days have passed since you submitted to the Free Caller Registry and you are still seeing a spam tag on a specific network, you can escalate the issue directly to the analytics engine responsible for that carrier.

• AT&T: Submit a ticket directly via the Hiya Help Center.
• T-Mobile: Register the number on First Orion’s "Call Transparency" portal.
• Verizon: Report a legitimate number incorrectly tagged on the TNS Call Guardian portal.

5. "Warm Up" Your Phone Number

Algorithms look for volume spikes. If a number goes from zero calls a day to 500 cold calls a day, it triggers an immediate block.

• The Fix: Treat your new phone number like a new email domain. Warm it up gradually. For the first week, make a low volume of targeted, high-quality calls where you know the recipient is likely to answer (like existing clients or vendors). A history of answered calls tells the algorithm that you are a legitimate human making legitimate calls.

Start with a Clean Slate

Dealing with spam flags is a headache, but it is the reality of modern outbound calling. One way to mitigate this risk from the start is by acquiring brand-new, never-before-used business numbers through a reputable, premium vendor—like RingBoost—rather than buying cheap, heavily abused recycled numbers from a bargain-bin VoIP broker.

Register your numbers, verify your identity, and warm up your call volume. Your connect rates will thank you.
