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.

Lawrence, what you say may be generally true, but not always. For months now I've had 3-4 "Unknown" or "No Caller ID" calls per day, and if I *do* answer them, thecaller disconnects. If I don't answer them, no voicemail is left me. I'm pretty sure no one hates me enough to continually pester me this way. Rather, I believe this may be a mining scheme to record voice ID data, or some other scheme I can't even imagine. I appreciate your kindness and patience to give your time answering forum questions. I come down on the side of those who want the choice whether to block unknown callers. Maybe it used to. be a "bad idea," but no longer. Apple should do this.

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.

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.

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!

The only way to block your caller ID is through your carrier. It isn't really a feature of the phone; the switch on the phone just notifies your carrier's network that you want your caller ID blocked. Most carriers support the standard code *67, but it must be entered as part of the phone number each time. That is, to call +1.555.555.5555 you would key in *6715555555555. If you want to always block your caller ID you must contact your carrier's account management. My carrier has this as an option when I log into their online account management.


If your carrier doesn't offer it check with other carriers; in some countries it is illegal to block your caller ID.

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.

Thank you for your quick answer. Currently there is only one way to do: edit Do Not Disturb mode and allow calls from everybody group, but it is a bit of “hacking” or “not so ease use” for ordinary user. Collateral damage are only end users that are forced to ignore Hidden ID abusers because of (not always correct) law. Can you imagine what would happen if end user is public figure (President, for example) - what he has to do to stop being annoyed by Hidden ID abusers? Please implement this feature and add “I agree terms of use” and that would be it. No pain & everybody will be happy :)
