Receiving calls from unknown numbers can be frustrating and potentially risky. Fortunately, there are several methods to identify these callers and protect yourself from unwanted interruptions.
What Are "No Caller ID" and "Unknown" Calls?
"No Caller ID" calls occur when the caller intentionally hides their number, often using features like *67 in the U.S. "Unknown" calls typically refer to numbers that your phone doesn't recognize, which could be due to various reasons, including network issues or the caller's number not being registered.
How Can I Identify an Unknown Caller on My Mobile Phone?
1. Use Built-in Features on Your Smartphone
- iPhone Users: With the release of iOS 26, Apple introduced a feature called "Call Screening." This feature intercepts calls from unknown numbers and prompts the caller to state their name and reason for calling. The response is transcribed and displayed as text, allowing you to decide whether to accept or decline the call. To enable this feature:
- Go to Settings.
- Tap on Phone.
- Select Screen Unknown Callers.
- Choose Ask Reason for Calling.
This feature is available on iPhones compatible with iOS 26 and later. (techradar.com)
