By Jessica RegheliniUpdated on February 21, 2018

Tired of getting annoying phone calls from unknown numbers? Want to block unknown numbers from calling you? If so, you’re in luck! Today, we’re going to show you how to block “no caller ID” calls on your iPhone.

First of call, what exactly does it mean when you see “No Caller ID” pop up on your phone?

What does “No Caller ID” mean?

When you see a call from “No Caller ID” appear on your screen, it means that the person who is calling you has stopped their phone number from being visible to you. This means that they purposely want to hide their contact information from you so that you cannot trace the call back to that person.

Who could be calling you?

When you receive a call that appears as “No Caller ID,” it could be coming from

  • A telemarketer trying to sell you something.
  • An organization or charity looking for donations.
  • An individual who wants to call you without you seeing their number.

Although you don’t know who is calling, you do know that they don’t want you to have their contact information.

That covers what “No Caller ID” means and who could be calling you from one of these blocked numbers. The next thing we need to address is how you can go about blocking these kinds of calls on your Apple device.

5. Select All Contacts.

The last step is to select All Contacts. After tapping it once, you should see a small check mark appear on the left side. This means that all of your saved contacts will be able to call you, and you won’t be notified of calls from anyone who is not saved as a contact. However, someone tries to call you from a number that is not saved to your contacts list, it will still appear in your call history as a missed call.

Notes on blocking “No Caller ID” calls

1. Keep in mind that this method simply stops you from getting notified of calls from unknown numbers.

Using this method will stop you from getting notifications of calls from unknown numbers. It will not, however, stop those people from calling you in the first place. It simply stops the annoying notifications of calls.

2. You can also try adding 000-000-000 to your blocked list.

In our research, we found that some people recommend adding an entry to your contact list with 000-000-0000 as the phone number. Save this entry as “No Number” or “Do Not Answer” – or something else to that effect. Then, add that contact to your blocked list.

3. Get in touch with your service provider to see if they offer an unknown number blocking service.

Your mobile service provider may have an option to add to your monthly plan that will prevent unwanted calls automatically. We’d recommend calling your provider’s customer service department to ask if they offer anything like this.
