How to block" No Caller ID " call from my iPhone

You cannot do it from the device. However, you can contact your carrier (mobile operator) & let them know that you would like to sign up for DNC list. Make sure to tell them you do not want anyone on the DNC exception list.

So next time you will be receiving calls will only be from telemarketers who have registered themselves with DNC (hence must have to display their number) or you have specifically added them to your exception list (eg. your favourite restaurant, salon etc.). If you get more "NO CALLER ID" calls after DNC registration, you can file a legal complaint either through your carrier.

Got my first “NO Caller ID” today. Yes, I know it is impossible to block them but for selecting “Decline” or double-clicking the side button. But your periodic responses on the order of “Start by reading the other posts in the thread you just posted to” are not particularly of interest. Might I humbly suggest: en boca cerrada no entran moscas.

There are app available on App Store which can trap and trace "No Caller ID" and give you the number. I do not want to name any of the Apps because that will sound like advertising.

Take a pick on your own.

Once you have it block them.

The "aid" suggested within this reply is DANGEROUS.

Reason: The calls are not blocked, they are merely silenced.

That means: If e.g. an unwanted person calls you, they will still get through and only get the impression that you simply do not answer the phone.

In the case of patient hard-case type callers (e.g., stalkers, ex-girl/boyfriends etc.), this can actually further agitate the caller and motivate him to pursue further means of contacting you (e.g. paying people a visit, sending receipt-requested letters etc.).

In contrast: Blocking unwanted callers through the standard iOS blocking feature immediately cancels ingoing calls, giving the impression that your number is disconnected / not available, which would be the expected & desirable behaviour.

Cheers,

How can I block No caller ID

There are 11 pages in this thread. On every one of them it is explained that it is not possible to block calls from unknown callers. Yet you still found it necessary to ask.

This user-to-user forum, where Apple doesn’t participate, isn’t a useful place to ask for anything. The right place is https://Apple.com/feedback.

I also suggest reading the thread you posted to, which has a lot of info, some useful, on this issue.

Finally I’ve found one way:

How to block “No Caller ID” unknown / hidden calls on iPhoneX

My question would be: how to create other “Groups” in iPhone contact list? That would solve few more problems and make life easier - Currently only “Favorites” and “All” exists as groups. Can (and how) I can add one more group?

Edit: I’ve found it! Here is a tutorial link:

How to create new contact group on iPhone:

You can create groups from the contacts app in your account at www.icloud.com - https://support.apple.com/kb/ph2667?locale=en_US

And that video hint does not stop only calls with no caller id. It stops all calls, from anyone and everyone, not in the “allowed” contacts group.

What is needed is for cellular telephone service providers to implement anonymous call blocking - something they’ve routinely offered to landline subscribers for decades now, but have steadfastly refused to implement on their cellular telephone networks.

You are wrong about collateral damage. Here's another example. Your doctor has just received test results that indicate you have a critical condition that requires immediate medical attention (e.g., dissected aorta, ecg indicating a imminent heart attack, blood test showing tetanus or rabies, you have been exposed to ebola, etc) but she is home. So she blocks her caller ID to not give away her private phone number. But she can't reach you because you have blocked unknown caller ID. And a caller doesn't know that caller ID has been blocked (that's the way it works) so she doesn't know to try a different way of contacting you. A little imagination can find many other similar examples. If Apple blocked that call an enterprising lawyer would think of suing Apple. As I pointed out, Apple made a conscious choice to not block "no caller ID" calls. It's not that they can't; they have carefully chosen not to. Maybe they know more about it than you do.

It's mostly irrelevant anyway; spam callers almost never block their caller ID; instead they send a fake caller ID that looks like a number you might answer such as another number in your town. I got one recently where the spoofed number was that of a nearby hospital. I had to answer it because I was waiting for a callback from a doctor at the hospital. But instead I was told I had won a fabulous vacation.

That's because you can't do it. That fact has been posted in this 7 page thread many times, so you should be able to find it.

As has been explained repeatedly in this thread, you don't.

Hello. THANK YOU SOO MUCH! Been plagued up to three times a day by withheld number. It's actually a double glazing firm that I asked to be removed from their d/b. They then switched to calling from unknown number. Not just me hundreds more. Thanks to you I now have peace. A grateful technophobe 🙂

you can block all numbers not in your contact list by doing this:

1. go to settings
2. open "Do Not Disturb"
3. slide on "Manual"
4. tap on "Allow Calls From"
5. Select "All Contacts"

All calls from numbers not on your contacts list will now be blocked. You can however still see all numbers that attempted to call you as missed calls. Verify the numbers and if legit, add them to your contacts list to receive any future calls from them.
