Understanding “Anonymous Caller IDs” in Incoming Calls

Sometimes, incoming calls may show “Anonymous,” “Private Number,” or “Unknown Caller” instead of a phone number. This is common in VoIP environments and is usually related to caller privacy—not a system issue.

What does “Anonymous Caller ID” mean?

It means the caller’s number is intentionally hidden or not transmitted by the caller or their service provider. As a result, the number cannot be displayed.

Why does this happen?

  • Many VoIP providers allow users to hide their caller ID.

  • Caller ID (CLI) may be suppressed for privacy or security reasons.

  • When a call is sent without a visible ID, platforms like CallHippo cannot show the number.

Important: If the caller ID is hidden by regulations or a third-party provider, it cannot be forced to display.
