Phone Number Displaying as Spam

On occasion, while making normal day-to-day outbound calls, agents may begin receiving reports that their outbound calls are displaying as "Spam”, “Spam Likely", “Potential Spam” or other similar designations. does not have direct control over your spam designation, nor do we have visibility on which numbers are being marked as spam. This designation is made by the external carriers receiving their call. Each carrier has their own algorithm to identify "spam" behavior. On modern smartphone devices, receivers of that call often have the ability to report a call as spam to their carrier.

Registering your Numbers with the Analytics Companies

The FCC has established this free registry site which covers the main analytic companies that support the major wireless carriers in the US that can register your numbers and remove a negative label on a call:

The three major analytic companies and the related carriers can be found below. A submission can be made directly if your request is urgent.

Once you've registered your Numbers with the FCC, they will pass along the request to these three companies, which will register the numbers to your business in their system. If there are any spam designations found, they may decide to remove the spam designation. Registration is not guaranteed to remove a spam designation.

If your registration is urgent, we recommend submitting to the analytics companies directly. You can usually expect a response within a few business days. The approval timeframe through the FCC registry can vary based on the volume of numbers submitted, but a good estimate is 2-4 weeks from the time of your submission.

  1. STIR/SHAKEN is a suite of protocols and procedures intended to combat caller ID spoofing on public telephone networks.

  2. Voice Integrity is a free offering which will let you register your phone numbers with the Analytics Engines used by the major carriers in order to lower the chance that they are mislabeled as spam. Read more: Understanding Voice Integrity
  3. Configure a Branded Caller ID for your Numbers so that they display a custom name (note that this custom name is limited to 15 characters or less for most devices). While this does not remove or prevent the spam designation, it makes your number more easily recognizable which could make it less likely to be flagged as spam in the future.
