Outbound Calls Showing as “Spam Likely” or “Spam Risk”

If your business number is displaying on mobile phones as “Spam Likely,” “Spam Risk,” or similar, it means your number has been flagged by a carrier’s call analytics system.

This is not caused by your phone system.

Mobile carriers use third-party reputation databases to determine how calls are labeled.

Why It Happens

Common reasons include:

• Many recipients declined or blocked your calls

• Your number was spoofed by scammers

• High outbound call volume or short call durations

• Repeated calls with low answer rates

Even legitimate businesses can be flagged if calling patterns resemble robocalls.

What You Should Do

The major U.S. analytics providers (Hiya, First Orion, and TNS) participate in a shared registration system.

Businesses should proactively register their outbound numbers here:

Registration helps:

• Associate your business name with your numbers

• Reduce spam labeling

• Submit remediation requests if flagged

Additional Best Practices

• Avoid large call bursts from a single number

• Ensure customers expect your calls

• Honor opt-out requests immediately
