iPhone users often reported that they received calls from hidden phone numbers. It can be a possibility that you are tired of answering unwanted calls every day and you wonder if there’s any way to block them.

So, here we’ll discuss how to block no caller ID calls on iPhone by using three simple Apple-certified ways. Let’s check them out.

Block No Caller ID Calls On iPhone using Do Not Disturb Method

The “Do Not Disturb” feature in iPhones is something that you can use when you have to focus on something and don’t want to get disturbed by any notifications. Activating the feature will help you to mute calls, app notifications or any other alerts even when your phone is locked.

The same feature will also help you to get rid of private calls notifications that show “no caller ID”. Here’s how you can set up “Do Not Disturb” on your iPhone.

1. Open Settings on your iPhone.

2. Scroll down until you find the Do Not Disturb option.

3. Activate the toggle you see next to the Do Not Disturb option on the next screen. You will see a moon-like icon on the status bar when the do not disturb mode gets activated on your iOS device.

4. From the next menu, scroll to the bottom and select All Calls which will show All contacts in the updated version. You can see a small checkmark appears on the right side of it. 

Now your iPhone will only ring when people from your phone contact book call you. Calls from unknown and no caller ID will be muted.

2. Type 000-000-0000 in the phone number box and save it using No Caller ID, Do Not Answer, or No Number.

3. Once you do it, again open the phone app and find the contact you have just created and then select it.
