Cell Phone Carrier SPAM Explanation/Resolution

Why Are My Calls Showing as “Spam” or “Spam Risk”?

Mobile phone carriers use third-party analytics companies to identify and block unwanted or fraudulent calls. These providers analyze calling patterns, volume, and user feedback to determine whether a call should be labeled as Spam, Spam Risk, or similar.

Unfortunately, legitimate business numbers can sometimes be flagged by mistake — especially if outbound calling volume increases suddenly, numbers are newly activated, or calls are frequently unanswered.

How to Remove a Spam Label

To have the spam label removed, you must submit your number for review with the carriers and analytics providers that manage these reputational databases.

We strongly recommend registering your numbers with the Free Caller Registry .

This free, centralized portal allows legitimate businesses to submit their caller information once, which is then shared with the three primary call analytics providers:

  • First Orion
  • Hiya
  • TNS (Transaction Network Services)

Registering here is often the fastest and most effective way to resolve spam labeling across multiple carriers at the same time.

Step 2 — Submit Directly (If Needed)

If the issue persists after registering with Free Caller Registry, you can submit requests directly with carriers and analytics providers using the links below:

Important Notes

  • Spam labeling is controlled by carriers and analytics providers — not by LineOne.
  • Removal requests must be submitted by the business using the phone number.
  • Review and removal timelines vary and may take several days to a few weeks.
  • Maintaining consistent calling patterns and avoiding high-volume burst dialing can help prevent future labeling.
