Why Does "Spam Likely" Appear?

When your business calls show up as "Spam Likely" on your customers' phones, it's not just annoying—it can seriously hurt your business. Customers don't answer spam calls, and your legitimate outreach goes ignored.

Carriers like AT&T, Verizon, and T-Mobile use sophisticated algorithms to detect potential spam calls. These systems analyze:

    1. Call volume patterns
    2. Call duration (very short calls are suspicious)
    3. Customer complaints
    4. Caller ID consistency
    5. Geographic calling patterns

How Carriers Flag Numbers

Each major carrier has its own spam detection system:

AT&T

AT&T's Call Protect service analyzes billions of calls to identify spam patterns. Numbers flagged by their system show "Spam Risk" or are blocked entirely.

Verizon

Verizon's Call Filter uses machine learning and a network-level spam filter. They maintain databases of known spam numbers and analyze real-time calling behavior.

T-Mobile

T-Mobile's Scam Shield is one of the most aggressive systems, blocking scam calls by default for many customers. They use Scam ID and Scam Block features.

Steps to Remove Spam Likely Labels


1. Register with Free Caller Registry

The Free Caller Registry is a database where legitimate businesses can register their phone numbers. While not guaranteed to prevent spam labels, registration signals to carriers that your number belongs to a real business.


2. Submit to Carrier Whitelists

Each carrier has programs for legitimate businesses:

    1. AT&T Business: Contact AT&T Business services to verify your numbers
    2. Verizon Business: Use their Caller Name Delivery service
    3. T-Mobile: Submit through their Business Verified Caller program


3. Maintain Consistent Caller ID

Your outbound caller ID should always display:

    1. Your actual business name
    2. A real, callable phone number
    3. Consistent information across all calls

Changing caller ID frequently is a red flag for spam detection algorithms.


4. Monitor Your Call Patterns

Spam detection looks for:

    1. High call volumes from a single number
    2. Many short-duration calls (hang-ups)
    3. Calls to sequential phone numbers
    4. Geographic inconsistencies

If your legitimate business activities trigger these patterns, consider spreading calls across multiple numbers or adjusting your timing.


5. Implement STIR/SHAKEN

STIR/SHAKEN is an industry standard for caller ID authentication. When your calls are properly attested, carriers know your caller ID hasn't been spoofed. Phone2 automatically implements STIR/SHAKEN for all outbound calls.

Prevention Tips

Build Your Reputation Slowly

New phone numbers don't have calling history. Start with low volumes and gradually increase. This builds a positive reputation with carrier systems.

Use Business VoIP Services

Consumer phone lines often lack proper business registration. VoIP services like Phone2 provide CNAM (Caller Name) registration and proper carrier authentication.

Respond to Complaints Quickly

If customers report your number as spam, address it immediately. Contact carriers to dispute false reports and ensure your calling practices don't generate legitimate complaints.

What Phone2 Offers

Phone2 helps businesses avoid spam labels through:

    1. Number Reputation Lookup: Check if your number is flagged before it becomes a problem
    2. CNAM Registration: Your business name displays correctly on caller ID

    6. Carrier Relationships: We work with carriers to register legitimate businesses

When to Get a New Number

Sometimes, a number's reputation is too damaged to recover. If you've tried all remediation steps and still get flagged, consider:

  1. Getting a new business number through Phone2
  2. Properly registering the new number from day one
  3. Building reputation slowly with low volumes
  4. Keeping the old number for incoming calls only

Conclusion

Getting labeled as "Spam Likely" isn't permanent, but fixing it requires proactive steps. Register your numbers, maintain consistent caller ID, and use a business phone service that properly authenticates your calls.
