What is a Spam List?
A spam list is a registry containing phone numbers suspected of being used for unsolicited or fraudulent calls. One well-known example is the National Do Not Call Registry, created in 2003 and managed by the Federal Trade Commission (FTC). The primary goal of this and other spam registries is to protect consumers by reducing the volume of unwanted calls.
How Did I End Up on a Spam List?
If your customers are reporting that your caller ID shows up as “Spam Likely,” it is because your number has been flagged on a carrier registry. Carriers and third-party analytics providers make these determinations algorithmically. They review call patterns (such as high volume in a short window) and user feedback—specifically, when recipients manually report your number as spam.
How Do I Remove Myself from a Spam List?
Don’t worry—being flagged isn’t permanent. There is a straightforward process for getting your number cleared, though it does require a bit of legwork. You must fill out individual forms for each major carrier. Currently, there is no single “universal form” to handle this for every provider at once.
The goal of these forms is to confirm that you are a legitimate business using your number for valid purposes. In some cases, a carrier agent may contact you for final verification after you submit your request.
Forms to Fill Out
Use the links below to request a review of your phone number. We recommend starting with the shared registry first, then moving to carrier-specific forms if the issue persists.
- Free Caller Registry:
This is your best first step. It is a shared portal used by major call analytics providers. You can register up to 20 numbers at once. While it doesn’t guarantee removal, it is the most efficient way to reach multiple providers simultaneously. - Verizon:
If calls to Verizon customers are being mislabeled, submit Verizon’s spam feedback form to request a categorization review. - T-Mobile:
Use T-Mobile’s improperly identified calls form. Note that they may use your email to create a login for future tracking. - AT&T / Hiya:
AT&T utilizes Hiya for their analytics. Use the Hiya support form and select “Report a possible issue of spam labeling.” Briefly explain that legitimate clients are missing your calls due to the label.
After submitting, monitor your call results for a few business days. If the “Spam Likely” label remains, your call patterns or authentication (STIR/SHAKEN) may need further technical review.
