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 or malicious calls.
What Does "No Caller ID" Mean?
When you see "No Caller ID" on your phone, it indicates that the caller has intentionally blocked their number from being displayed. This is different from an "Unknown Caller," which means your carrier couldn't retrieve the number. (asurion.com)
