How to Tell if It’s a Spam Number

There are a few key things to listen for when trying to determine if a “no caller ID” number is spam or not. First, pay attention to the number of times the call is made. If you receive multiple calls from the same number within a short period of time, it’s likely that the caller is a telemarketer or robocaller using an automated system to place multiple calls.

Another telltale sign of a spam call is silence on the other end after you answer; this usually indicates that the caller is using an auto-dialer and hasn’t yet reached a live person. Finally, be wary of any unexpected or unsolicited sales pitches, especially if they’re made before you’ve had a chance to say hello. If you’re getting an onslaught of these types of calls, chances are good that it’s spam.
