What Does No Caller ID Mean? (Caller ID Explained)

Each of us had the experience of receiving calls from unknown callers - phone calls from a No Caller ID service or an Unknown Caller at least once in our lives. These types of calls can be very annoying, especially when we are getting them in the middle of a business meeting or an important event in our lives.

In addition, we wonder what the actual meaning of these calls is and how they differ.

In this blog post, we’ll explain all of that, so keep on scrolling to find out all there is to know about this.

Note to Remember: The main difference between a call stating “No Caller ID” means that the caller is trying to hide his number and “Unknown caller” means that your mobile operator hasn’t interpreted the number.

What does No Caller ID mean?

Basically, a “No Caller” ID is a telephone feature that displays the caller's phone number on the recipient’s phone before answering the call. It means that the caller has intentionally hidden their number from showing up on your screen when they try to call you. In other words, the caller has blocked their number from appearing when they call you.

For those that didn’t know, this option is not available on every cell phone and depends on the carrier provider one uses some phones to allow users to hide their numbers at all times (till they turn off the feature for doing so).

What does Unknown Caller mean?

When you get the message “Unknown Caller” on your screen, it means that the telecom service operator could not identify the number. It means that the caller might be calling from another country, or perhaps there might be some kind of network issue.

What is the difference between “No Caller ID” vs. “Unknown Caller”?

Truth be told, both No Caller ID and Unknown Caller achieve the same objective; however, there is still a big difference between them. The first refers to the caller who deliberately chooses to hide their phone number by using the feature being available on their phone.

The latter, Unknown Caller, refers to the inability of the service provider companies to identify/interpret the phone number due to some restrictions.
