Well, the good news is that by using the best robocall blocker, you can easily block any number on your phone. In this guide, I will teach you how to block unknown or private calls on iPhone in two ways.

Block Calls on an iPhone using its inbuilt Feature

Apple understands that there are times when we simply wish to blacklist certain callers from contacting us. For this, it introduced an inbuilt feature to blacklist calls. You can access this inbuilt feature on devices running on iOS 7 and later versions. You can either go to your call log for this or your phone’s settings. While the overall interface on different models might vary, here’s how you can block private/unknown calls on iPhone.

1. If the contact is not saved and you have recently got a call from it, then juts open your call log. From here, you can identify the number or contact and tap on the “i” button to get more details.

2. This will open various details about the caller or the saved contacts. Simply scroll down and tap on the “Block this Caller” button to add the number to the blacklist.


3. Alternatively, you can also go to your iPhone’s Settings > Phone and enter the “Call Blocking and Identification” settings.

4. Now, tap on the “Block Contact” button to get a list of the saved contacts. You can add multiple contacts to the phone’s blacklist this way.

5. Once the contacts are added, you can just view them under the “Blocked Contacts” list here. Under the Call Blocking and Identification settings, you can also see if you have installed any third-party call blocker that you can enable/disable from here.
