How to Block ‘no Caller ID’ Calls on iPhone

Now that we can block calls on the iPhone by selecting a specific number or contact, would not it be good to go further and prevent all “Unknown” and “No Caller ID” calls from reaching the iPhone as well? Typically the calls “Unknown”, “No Caller ID”, and “Blocked” are telemarketing calls, thefts, and other annoying types, so it is not as if you were going to lose a lot if we avoid that these annoyances get in touch with us.

We will show you an intelligent solution that prevents all “Unknown” calls and all “No Caller ID” calls from calling an iPhone, and also prevents any other unrecognized number from reaching you.

Do not use this method to block unknown calls if you regularly receive desired telephone calls from numbers or callers from unrecognized numbers and numbers. This works by using the contact list on your iPhone as the list of allowed calls. Anyone who is not on your contact list will not be able to communicate with the iPhone.

What Is No Caller ID Call?

You can not make caller ID calls on any smartphone and they are normal phone calls, but they purposely decided to delete your caller ID.

You can not refer to caller ID calls as masked calls, unknown calls, and hidden calls.

There are some reasons why someone decides to hide their number.

How to block “Unknown Caller” and “No Caller ID” on iPhone

This is not the traditional block call method, it is a smart solution that uses Do Not Disturb mode and your contact list to prevent random strangers from reaching the iPhone. There are some caveats, so be sure to read and understand how this works.

Follow Below Steps:

  • Open the Settings application on the iPhone and go to “Do Not Disturb”
  • Put the switch next to “Manual” in the ON position – this activates Do Not Disturb mode (as meaning by the moon icon) that essentially keeps your phone silent, let’s customize it.
  • Click on “Allow calls from”, from here you have two options of restrictions.
  1. Choose “Favorites” if you only want your’Favorites’ contacts to communicate with your iPhone, this is an acceptable solution for people who have family, friends and other important people on their iPhone favorites list, but never receive calls from anyone who is not in “Favorites”
  2. Or: Choose “All contacts”, which will allow phone calls to pass from anyone in your contact list (not just favorites) but not anyone who has not been added to your address book – this is the best solution for many, since obviously an unknown call, a lawyer, or a “No Caller ID” call will not be in your iPhone’s address book, but if all the people you communicate with are on your list of contacts on your iPhone, you will not miss your calls.
  • Exit Settings and enjoy your new peace and quiet.

Selecting “All contacts” will prevent any phone number or address that is not on your iPhone contact list from reaching the iPhone. Do not enable this without a full understanding, otherwise, you may lose calls you really want to receive.


That the Do Not Disturb mode completely silences the iPhone, leaving the iPhone not ringing or making an alert sound, and avoiding any contact attempt if someone is not on your Favorites list or in the Contacts list, assuming that you chose any of those options. Due to its design, Do Not Disturb mode is an excellent feature, but it is generally best used on a schedule so that it is automatically activated at night and automatically turns off in the morning, but some people like to have it on all the time.

It is also highly recommended to activate the option “Repeated calls” in the Do Not Disturb mode since it is unlikely that someone who is not in an emergency situation will repeatedly call the iPhone.

Obviously, if you do not have a contact list and there is no one on your favorites list, you may want to add the people you would like to talk to the iPhone with or reconsider the use of the Do Not Disturb trick to block unknown calls. If you enable it without having a sufficient contact list, you will basically be blocking all calls to your phone, which is not what most people want to do.

Think, how many times have you answered an unknown call or a “No Caller ID” number and if it was something important or something you wanted to talk about? For me anyway, it’s 95% of telemarketers, political robberies, call scams and other junk, and I can only think of one time that someone who really knew manually blocked their iPhone number from appearing on the identifier of calls with the prefix> * 67 prefixes.

Blocking calls from Unknown and No Caller ID is very little, but Apple has yet to offer a direct solution to this, so in the meantime try this Do Not Disturb trick. Or just get used to mute a call you do not want to answer when you arrive,

Another trick that used to work was to create a contact called “Unknown” and “No Caller ID” and block those contacts specifically on the iPhone, but that does not work reliably, so if you really want peace and quiet and avoid people strangers harass your iPhone, use the DnD method instead.
