Receiving calls from private or unknown numbers can be unsettling, especially when they turn out to be spam or scams. In the United States, several apps and services claim to identify these calls, but Robokiller stands out as a market leader in providing comprehensive protection against unwanted calls.
What Are Private Number Calls?
Private number calls, also known as unknown or blocked calls, occur when the caller intentionally hides their phone number. This tactic is often used by telemarketers, scammers, or robocallers to conceal their identity and avoid detection.

Robokiller employs advanced technologies to identify and block private number calls:

Call Screening: This feature screens unknown callers by informing them that your number is protected by Robokiller, asking for their name and the reason for the call.
