How to Block Unknown Callers in iPhone Natively

Last Updated: November 30, 2016

iPhones offer an easy way to block callers by their numbers; so, if you get a spam call, you can easily block it. However, what if you just didn’t want any calls from those pesky unknown callers, and no caller ID numbers? Unfortunately, there is no direct way to that, yet. However, don’t worry, we’ve got your back. As it turns out, there is a simple work around that will automatically block any calls from unknown callers, and those “No Caller ID” numbers on your iPhone:

Block Unknown Callers using Do Not Disturb

Do Not Disturb is an extremely useful feature in iPhones. It allows you to focus on whatever task you have at hand, and not get distracted by your phone constantly lighting up, and playing notification tones, every time you get a message or a call. Do Not Disturb can be scheduled, or it can be turned on manually. So, here is how you can use Do Not Disturb mode to block calls from unknown callers, and no caller ID numbers:

1. On your iPhone, go to “Settings -> Do Not Disturb“. Here, flip the switch next to “Manual” to “On”.

2. Now, tap on “Allow Calls From“. By default, this would probably be set to “Favorites“. Change it to “All Contacts“.

3. Go back, and under the section that says “Silence“, select “Always“. This will ensure that you don’t get calls from unknown callers, even if you’re using the phone, and the screen is on.

That’s it. Since you have Do Not Disturb mode on, it will not notify you of calls from unknown callers, and no caller ID numbers. You can now get back to working, and not get bothered by anyone who is not in your contacts list. No more of those pesky spam calls for you! Enjoy!

Bonus: Repeated Calls

The only drawback of using a workaround such as this one, is that you will not get notifications for genuine calls that are made from a number which is not in your contacts list. While that may be okay, it could be a problem if the other person is in an emergency, and needs your help. So, in the Do Not Disturb section, make sure that you turn on “Repeated Calls“.

All this does, is, if someone calls you from an unknown number, and then calls you again, within three minutes, your iPhone will not block that call, and will notify you about an incoming call. So, unless spammers repeatedly call numbers in your area, you can safely turn this on, and only be bothered by unknown callers, who really do need to talk to you.

Block Unknown Callers and No Caller ID Numbers on Your iPhone

I don’t know why there isn’t an option to directly block unknown calls on iPhone. Thankfully, if you really want to block those calls, this workaround will definitely work for you. Be careful, though, because if you use this, you will not get any calls from numbers that are not saved in your contacts list.
