In the profile for this new contact, type in “ No Caller ID” under the name.Navigate to the Contacts on your phone and tap the + to add a new contact to your phone.Your iPhone will now recognize any hidden or private numbers as a blocked number and prevent your phone from ringing should someone call you from an unknown number. Select Block Contact to confirm your choice.Next, scroll through this newly added contact’s profile until you see the Block this Caller option and tap on it.Then, key in “ 00” for the phone number of the new contact.Enter “ No Caller ID” into the box for the contact’s name.Navigate to Contacts and tap the + icon to add a new contact.However, creating a contact that mimics this unknown number allows you to work around this. The third way to block unknown numbers is by creating a new contact that you can name “Do Not Answer” or “No Caller ID.” Unfortunately, your iPhone cannot block hidden or private numbers because it cannot recognize them.

However, it prevents all other calls from coming through, which means you may miss other important calls from numbers other than those in your contact list. This solution works because it allows only those people stored in your contacts list to call you. Close the menus and navigate back to your Home screen.Tap on Allow Calls From and then choose the All Contacts option.Now, scroll through the menu and tap on Do Not Disturb.Unlock your iPhone and click on the Settings icon.
