How to Unmask No Caller ID and Unknown Phone Calls

It’s unpleasant when you get calls from private numbers or unknown caller ID. These kinds of calls are unscrupulous in nature and are usually spam calls that advertise products or make false claims.

People who receive these calls often have the same question: “Who called me from this phone number”.

With the rise of caller ID spoofing, many businesses are using this tactic to hide their names and numbers so that you will answer their calls and give in to their nasty tricks.

With a simple method that takes a little tech-savvy and less than 5 minutes of work, this post will teach you a way to unmask No Caller ID phone calls and find out who’s actually behind a call.

What does No Caller ID mean?

The meaning of No Caller ID or Unknown Caller is precisely what it sounds like: the person who is calling you has apparently blocked their name and number from appearing on your phone. This can occur for various reasons, and the caller may or may not be aware they have done this.

When a call comes in from an unknown caller, it means that the caller’s phone number has been blocked by the caller and cannot be found by your carrier. That is why you are notified of these calls as “No Caller ID”, “Private Number”, or “Unkown Caller”.

These calls may be legit but there’s a high chance that it’s a robocall or a scammer calling you to get information out of you. You have to be very careful when answering these calls so as not to give out any personal details and banking information.

Here are some common reasons for No caller ID:

  • A telemarketer or scammer doesn’t want you to know it’s their calling.
  • Someone is trying to prank call you.
  • You are receiving harassing calls from an unknown number.
  • A person is calling from a location where their phone plan does not allow them to make calls with a caller ID (e.g., hotels, businesses).

Ways to unmask No Caller ID/Unknown Number/Private Number phone calls

If you want to unmask the private number, it is important to know that each carrier has a different method. Below are some of the most popular ways to unmask unkown numbers:

1. Copy and paste the “No Caller ID” on iPhone
