What Does No Caller ID Mean?

Getting frequent calls from a No Caller ID or an unknown caller can be frustrating, especially if they’re disrupting your everyday life. 

But, what does No Caller ID mean, what is the difference between No Caller ID vs unknown caller, and how can you find out who’s on the other side of the line without picking up the phone? 

Let’s find out. 

What Does No Caller ID Mean?

A No Caller ID means that the caller has deliberately hidden their number from showing up on your screen when making a call.

The feature is not available on all phones and it sometimes depends on your carrier provider whether you can hide your number when making phone calls. Some phones allow users to conceal their numbers permanently (until they turn the feature off) or hide their number on a per-call basis.

What Does Unknown Caller Mean?

If you get a call from an ‘Unknown Caller,’ it usually suggests that the service operator wasn’t able to identify the number.

A call from an unknown number might mean that the caller is calling from another country or that there is some kind of network issue, but it rarely indicates that the caller has deliberately hidden their number from you.

Difference Between No Caller ID and Unknown Caller

The difference between No Caller ID vs an unknown caller is that in the prior case, the caller is intentionally concealing their number when making calls. 

When you see a No Caller ID instead of a number, that means that the caller is purposefully hiding their number from showing up on your screen. On the other hand, an unknown number call suggests that the carrier provider cannot identify the number.

How to Block No Caller ID Calls?

If you want to stop receiving unsolicited and unknown calls, there are ways to block No Caller ID calls on both Android and iPhone devices.

To block No Caller ID phone calls on an iPhone:

  1. Go to ‘Settings.’
  2. Tap ‘Phone.’
  3. Scroll down to find the ‘Silence Unknown Callers’ and turn it on. 

Once you do, your iPhone will block No caller ID callers from contacting you.

If you’re an Android user and want to block No Caller ID calls:

  1. Tap on the phone icon.
  2. Tap on the three dots in the top right of the screen.
  3. In the dropdown menu, select ‘Settings.’
  4. Tap ‘Block numbers.’
  5. Toggle the ‘Block unknown callers’ button to turn it on. 

How to Unmask No Caller ID?

If you’re curious to see who’s on the other side of the line, you can either contact your telephone company or download a third-party app that can unmask No Caller ID calls.

Some phone companies offer an Anonymous Caller ID service, which can help you unveil an unknown caller with no number that’s been calling you. These services are not available with all phone companies and if they are, you’ll usually be charged a fee every time you use it. 

You can also contact the phone company and ask to identify the unknown caller ID. They may ask you about the date and the time when the unknown number was calling.

A third option is getting a third-party app to help you unmask a hidden or unknown phone number. There are plenty of apps available in Google’s Play Store and the App Store to choose from. Once you identify the phone number that was unknown or hidden, you can blacklist it to prevent it from calling you again.

Bottom Line 

The main difference between an Unknown Caller and a No Caller ID  is that the latter usually indicates that your phone company couldn’t identify the number that’s calling you, rather than the caller hiding their number intentionally. 

If you’re constantly getting phone calls from No Caller ID or an unknown number in the UK, there are ways to block them on both iPhone and Android devices or find out who they are (in most cases). 

Frequently Asked Questions And Their Answers

1. Does No Caller ID mean they are in your contacts?

It doesn’t necessarily mean that the person who’s calling you is in your contacts, but sometimes that could be the case. A No Caller ID doesn’t indicate whether you have the number saved on your phone or not. 

2. How to call with No caller ID?

If you want to hide your phone number, you can try entering ‘*67’ before the number you’re trying to call. Some phones also have a feature that allows them to make all calls anonymous. 

3. What does No Caller ID mean?

It means that the caller has deliberately hidden their number from showing up on your screen when making calls. If the call is from an unknown caller, then your carrier provider couldn’t identify the number.
