The question is to stop no caller ID not other contacts that are not saved. I don't mind receiving calls with numbers showing it's NO CALLER ID as stated above in the original question.

Has anyone found a way???? HELP x

Create a new contact, you may name this new contact “No Caller ID”. Here is how:

  • Launch the Phone app
  • Tap Contacts
  • tap the + button
  • As phone number, enter 000-000-0000
  • Tap Done
  • Now scroll down and tap Block this caller. A popup will appear saying “you will not receive phone calls, messages or FaceTime from people on the block list” then tap Block Contact.

3 years later and still you can't block bozos that withhold their numbers! i have downloaded and deleted 4 apps that say they can do this but they CAN'T as they ALL NEED AN INCOMING NUMBER and you don't need an app to block an incoming number as that is automatically set up in your phone settings! apple really need to do something - the only cretins that withhold their number are: overseas sales, trolls or abusive callers!

That's not technically true. While there is no number, the operating system, iOS, could very well give the user the option to config enable "Block all calls without caller ID data". So if a call comes in with no phone number, the phone never rings. It is doable - the phone can give the user the options of what to do when an incoming call is completely unidentifiable. But Apple chooses not to.

Dear Lawrence Finch, thank you for posting a useful answer, it really hurts when my mobile service provider has restricted its user's to use an incredible feature of iphone. It appears to be greyed out when ever i tap on

You can create groups from the contacts app in your account at -

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.

i've asked them and they don't do it - i even tried saving NO CALLER ID as a contact but that still doesn't work as it needs a number!!! however on utube there is a way of showing who the caller id actually is so next time i shall be trying it - it seems ok as it's not dependent on an app it is something that is in your phone BUT a lot of bother when you should just be able to BLOCK these *****!!!! and that's technical!

Having an option to auto-reject any incoming calls without at least a phone number would be a nice option to add to iOS.

It's really a bad idea. Most calls made anonymously are legitimate. For example, your doctor returning your call from her mobile (that she doesn't want to give out). Most spam calls are not sent anonymously; they are sent with forged phone numbers. Now, if there was a way to reject forged caller ID I'd vote for that, but it's not technically feasible (thanks to the wisdom of our legislators, who made it legal to create your own caller ID for outgoing calls). In a way there is, at least for VoIP calls; visit for information.

Could be a bad idea, but giving uses the CHOICE is the question, not whether its a good idea for everyone.
For me, I want it because I'll never answer a cell call from a blocked number. If I want you to call me on my cell, I'll give you my number and if its important you'll identify yourself. Don't want me to know where your calling from, fine, and I won't answer. My physician has other ways of contacting me.

I'd like to have the OPTION of making sure my cell phone does not ring for calls I know that I will not accept, so I don't spend time having to get the phone out and deal with the ringing.

The default could well remain the way it is - it rings in, but just allowing me to 'block' an 'anonymous/nonumber' call is an option I have.. don't see where thats an issue.

Blocking a call on the phone doesn't really block it; the call has already made it to the phone. All blocking does is send it to voicemail. You can easily do this yourself; if there is no number, just double-press the SLEEP button.

If you are serious about blocking numbers you should contact your carrier. They are the only ones who can block numbers before they are sent to your phone. Most carriers offer blocking services (including No CLID calls) for a small monthly fee.
