‘No Caller ID’ means the caller has intentionally hidden their phone number, while ‘Unknown Caller’ means the number isn’t shown due to a technical issue or network glitch. These two terms often confuse people when they appear on a phone screen during a call. ‘No Caller ID’ is a deliberate choice by the caller to block their identity, often for privacy or to avoid being recognized. ‘Unknown Caller,’ however, happens when the phone system can’t display the number, like with international calls or internet-based calls. This article explains what these terms mean, how they differ, and how to handle them.
What Does “No Caller ID” Mean on Your Phone?
‘No Caller ID’ shows up when the caller has chosen to hide their phone number. This happens because the caller uses a feature from their phone service to block their number from appearing on your screen. It’s a purposeful action, meaning they don’t want you to know who’s calling before you pick up.
How Does “No Caller ID” Work?
Phone companies offer a setting or code—like *67 in the U.S.—that lets users hide their number. When someone dials this code before your number, their call shows as ‘No Caller ID.’ This feature changes how the call data is sent, so your phone doesn’t receive the number to display.
Why Do People Use “No Caller ID”?
People hide their numbers for many reasons, such as:
- Protecting Privacy: Professionals like doctors or lawyers might use it to keep their personal numbers private when calling clients.
- Avoiding Callbacks: Telemarketers and scammers use it so you can’t call them back or report them.
- Making Surprise Calls: Friends might hide their number for an enjoyable surprise or a prank.
Examples of “No Caller ID” Calls
- A telemarketer calls to sell you something but hides their number to avoid being traced.
- Your friend dials *67 before calling to wish you a surprise happy birthday.
- A business contacts you for a survey without revealing their office number.
What to Know About “No Caller ID”

What Does “Unknown Caller” Mean on Your Phone?
‘Unknown Caller’ appears when the phone network can’t identify or display the caller’s number. Unlike ‘No Caller ID,’ this isn’t something the caller chooses—it’s usually a technical issue or a limitation in how the call is processed.
How Does “Unknown Caller” Happen?
The phone system relies on caller ID data sent from the caller’s network. If that data is missing or unreadable, your phone shows ‘Unknown Caller.’ This can occur due to:
- Network Problems: A glitch in the phone service might stop the number from showing.
- International Calls: Numbers from other countries might not format correctly for your phone.
- Internet Calls: Apps like Skype or WhatsApp sometimes don’t send a number, showing ‘Unknown Caller’ instead.
Examples of “Unknown Caller”
- A friend calls from Japan, and the number doesn’t display due to international network differences.
- Your phone company has a temporary issue, making a local call show as ‘Unknown Caller.’
- Someone uses a VoIP (Voice over Internet Protocol) service, and no number is linked to the call.
What to Know About “Unknown Caller”
This term doesn’t always mean trouble—about 10% of legitimate calls might show this way because of technical reasons. It’s less common than ‘No Caller ID’ but still worth understanding.
How Are “No Caller ID” and “Unknown Caller” Different?
