What is number reporting for?

Reporting a number helps improve the blocking lists. Reported numbers are analyzed and help identify carriers and number sources of unwanted calls. This makes the app more effective for all users.

How does a reported number become blocked?

A number is not blocked from the first report: it must exceed a certain number of reports before being added to the lists. This threshold prevents legitimate numbers from being blocked due to isolated or abusive reports.

• Numbers that exceed this threshold are added during the daily updates.
• Carriers that receive the most reports can also be added as a block.

Each report helps rank carriers by the number of unwanted calls they make.

Reporting a legitimate number

If a legitimate number was blocked by mistake, you can report it as legitimate in the app's "Report" tab. These reports also help improve the lists. To learn more, see What if a legitimate number is blocked?.
