Frequently asked questions.

Carriers and call-blocking apps use analytics engines that score every number based on calling patterns and consumer complaints. A spike in outbound calls, short call durations, a few spam reports, or a number's prior history can all trigger a label.

Legitimate businesses are flagged every day, usually without knowing it.

Usually you don't. The label appears on the recipient's phone, not yours. NumberGuard monitors the major spam databases and places live test calls to AT&T, T-Mobile, and Verizon devices, so you see exactly what your customers see.

Yes. AT&T, T-Mobile, and Verizon each rely on different analytics providers, and each provider scores numbers independently. A number can be clean on one carrier and labeled on another, which is why we monitor all three.

Because the same number can be labeled differently depending on the device. iPhones and Android phones receive and display caller ID information differently, and many Android phones add their own built-in spam detection.

For example, a number might show a spam warning on a Verizon iPhone while displaying normally on a Verizon Android, and the reverse might be true on AT&T. Testing only one type of device leaves blind spots, so we test both on every carrier.

We place live test calls on AT&T, T-Mobile, and Verizon using both iPhone and Android devices on each carrier, six combinations in total. We also monitor the spam databases those carriers rely on.

Spam labels appear without warning, often after a high-volume calling day or a handful of complaints, and they are not visible on your own phone. Continuous monitoring means you learn about a label in days rather than months, and remediation is already included when it happens.
