How it works
Continuous monitoring. Managed remediation.
NumberGuard monitors your numbers across the major spam databases and with live test calls on every major carrier. When a number is flagged, our remediation team manages the removal.
- 1
Add your numbers
Choose a plan and enter the business numbers you want monitored. NumberGuard works with any phone provider and requires no changes to your phone system.
- 2
We register your numbers
We enroll your numbers in the Free Caller Registry. Pro plans also include direct registration with the caller ID analytics providers the carriers rely on, establishing your numbers as a legitimate business.
- 3
We monitor continuously
We check your numbers against the spam databases used by carriers and call-blocking apps, and place live test calls to AT&T, T-Mobile, and Verizon devices on iPhone and Android, capturing exactly what appears on screen.
- 4
You are alerted immediately
If a number is flagged, you receive an email alert identifying the label and the carrier displaying it. Screenshots are available in your dashboard.
- 5
We remediate
Our remediation team files with each provider that labeled your number, manages all correspondence, and contacts you only if additional information is required. Remediation is included in every plan.
- 6
We verify the result
Once the label is removed, we confirm it with a follow-up scan. A case is closed only when your number returns to Healthy status.
Reputation protection
Protect your number before it gets flagged.
Your phone number is one of your most valuable business assets. NumberGuard protects it with continuous monitoring, and if a spam label appears, remediation is already included in your plan.
Continuous monitoring
Scheduled scans and live test calls detect labels within days, not months.
Remediation included
If a number is flagged, our team manages the removal at no additional cost.
Proactive registration
We register your numbers so carriers recognize them as a legitimate business.
Every carrier. Every device.
A number can be clean on one phone and flagged on another.
Each carrier relies on its own analytics provider, and iPhones and Android phones display caller ID differently. Many Android phones also apply their own built-in spam detection. A number can show a spam warning on a Verizon iPhone and display normally on a Verizon Android, while the reverse is true on AT&T.
Live test calls on six combinations
We place live calls to iPhone and Android devices on AT&T, T-Mobile, and Verizon and capture exactly what appears on each screen.
Spam database monitoring
We also check your numbers against the databases that drive carrier warnings and call-blocking apps, so issues surface early.
| Carrier | iPhone | Android |
|---|---|---|
| AT&T | Clean | Flagged |
| T-Mobile | Clean | Clean |
| Verizon | Flagged | Clean |
Protect your number before it costs you calls.
Most businesses never learn their numbers are flagged. They only see answer rates decline. Enroll online today, and our team handles the rest.
