How To Block No Caller ID Calls On iPhone

 

 

How to Block No Caller ID Calls on iPhone X, 11, and 12

 

 

Silence Unknown Callers

 

With iOS 13, Apple added a feature called Silence Unkown Callers. If you own a newer iPhone, iPhone X, and later, then you will be able to use this feature.&nbsp,

 

This feature silences calls from unknown numbers and sends them to voicemail. So, with this feature enabled, your iPhone won't ring for unknown numbers, but it will add the calls to your Recents list. This way you will know that someone tried to call you.

 

Also if an unknown number sends you a voicemail, you will receive a notification. This feature was extremely useful for me as I frequently receive spam calls from telemarketers, so enabling it felt peaceful.&nbsp,

 

This also works with no caller ID calls, so check out how to enable the Silence Unknown Callers feature, just follow these steps,

 

 

Step 1 Open the Settings app on your iPhone.

 

Step 2 Now, scroll down and tap on Phone.

 

Step 3 Find the Silence Unknown Callers options and toggle it on.&nbsp,

 

And that is it, you have enabled the Silence Unknown callers to feature on your iPhone. Your iPhone will stay silent for unknown numbers or no caller ID calls from now on.&nbsp,

 

 

Enable Do Not Disturb

 

Do Not Disturb (DND) mode is another way you can block calls from unknown callers with no caller IDs. This is a feature I love and use all the time to combat unknown callers when I am busy with something important. To put your iPhone into DND mode, follow these steps,

 

 

Step 1 Open the Settings app on your iPhone.

 

Step 2 Now, scroll down and tap on Do Not Disturb.

 

Step 3 Here, tap on Allow Calls From and then select the All Contacts option.&nbsp,

 

Step 4 Close the Settings app.&nbsp,

 

If you put your iPhone on DND mode without doing Step 3 then you won't receive calls from anyone. However, Step 3 will allow calls that are from your contacts so that you won't miss any important calls, while your iPhone will silence unknown and no caller ID calls. This way you won't get distracted or disturbed.&nbsp,

 

 

Create a New Contact

 

iPhones won't block hidden or private numbers if they cannot recognize them. So, to block such a number you can create a new contact and name it Do Not Answer or No Caller ID.&nbsp,

 

This means your iPhone will be able to recognize hidden and private numbers with no callers IDs as blocked numbers ad not ring in such cases. Just follow these steps,

 

 

Step 1 Open Contacts on your iPhone.

 

Step 2 Tap on the + icon to create a new contact.

 

Step 3 Enter No Caller ID or Do Not Answer in the contact’s name box.

 

Step 4 For the number, enter, 000-000-0000.

 

 

Step 5 Click on Done to save the contact.

 

Step 6 Now, in the contacts list, scroll down and tap on the new contact. Then tap on Block this Caller.

 

Step 7 Confirm by tapping on Block Contact.&nbsp,

 

This will let iPhone block any incoming calls that are marked as No Caller ID or Do Not Answer.&nbsp,&nbsp,
