iPhone Tip: How To Block Your Caller ID From Appearing on Other’s Phone

Caller ID is a common telephone service that allows you to see the caller’s phone number before answering the call. Conversely, when you make a call to someone, your caller ID will also appear on other’s phone.

For whatever reason you want to hide your caller ID from appearing on the callee’s phone, you can use one of the following methods to disable the caller ID feature.

Temporarily Block Caller ID

Generally, mobile operators offer special code for you to block your call ID on call-by-call basis. In case you just want to hide your caller ID for an individual outbound call, you can dial the special code prior to the number you’re calling to enable the blocking. Say, you’re in U.S. and want to dial 212-323-3322. In North America, you can use the special code *67 to disable caller ID. So instead dialing the number directly, dial *67-212-323-3322. This will prevent your caller ID from appearing and your callee will just see a “Blocked” call.

However, the special code varies by countries. According to Wikipedia, you can use the following special code to disable caller ID:

  • Argentina: *31*
  • Australia: 1831
  • Denmark and Switzerland: *31*
  • Germany: *31# (for some mobile providers may use #31#)
  • Hong Kong: 133
  • Israel: *43
  • Italy: #31# (most cell phone companies)
  • New Zealand: 0197 (Telecom) and *67 (Vodafone)
  • North America: *67
  • United Kingdom and Ireland: 141
  • Sweden #31#

Permanently Block Caller ID on iPhone

If you plan to block your caller ID for all calls, you can to go to “Settings” -> “Phone” -> “Show My Caller ID”. Simply disable the caller ID feature by turning the switch to OFF.

For now, when you make any call, your callee cannot view your caller ID and usually the number will be appeared as “Blocked” in other’s phone.

      Hi Manmeet, Disabling caller ID is not allowed in India. for this you need to get a special permission from the Police department.thats the reason you see this option disabled in india

    damn india lags in everything now even for disabling the caller id on iphone , people have to take permission from police.

    Thxs Sandeep.. Fr updating this information….

    This isn’t exactly germane to the article, but its related – and I’m not really sure where the proper place to ask it is, so I’ll just ask here…

    When just about anyone calls my landline, the caller ID will display the person’s # and name – even if I’ve never received a call from them before.

    If landlines have access to a magic caller ID directory in the cloud, why can’t mobiles? Why is it if the number isn’t in my phone book, all I get is just the number…. Can’t Verizon or AT&T or whoever also push the name along with it? I doubt it’d take that much extra data/bandwidth or whatever…. Maybe if the number is in my phone, the local data could take precedent – so it reads Mom instead of Barbra Jean Allen or whatever…. But it would still be nice to know who the occasional random caller not in my phonebook was….

    There is no comparable feature to temporarily turn-off the Caller ID on the Verison iPhone as is available on the ATT iPhone. Why was this feature eliminated? [It should not be necessary to input *67 each time to disable the Caller ID feature for each such call.]

    • Keith March 16, 2011 at 5:26 pm #

      Steph, did you ever get a reply to your question about hiding your caller ID on verizon iphones? I’m having the same problem.

    • drdeputy March 29, 2011 at 10:42 pm #

      Even in the iPhone 4 Portable Genius Verizon Edition it says you can disable CID, but it’s simply not a choice on the phone settings menu. Apparently Verizon doesn’t have the capability to do that remotely (they can do it if you call them), even though the book’s author thought it did. Just another difference between the ATT and VZ iPhones I guess. I would have liked the option to do it myself on occasion w/o having to go through VZ customer service.

    Thanks for some other excellent post. The place else may just anybody get that type of info in such a perfect approach of writing? I’ve a presentation next week, and I am at the search for such information.

    I am holding my Verizon iPhone 4s in my hands. Thre simply is no settings field that refers to turning on, turning off caller ID.

  8. DJ March 23, 2012 at 5:17 am #

    So this is basically the opposite of how it worked in the previous version? Before the upgrade, I would turn caller id off and I would dial *82 first (in US) if I wanted to UNblock my number. That doesn’t seem to work now. When I set “Show my caller id” to off, *82 doesn’t override the block and display my number.

    Now, I have to set show caller id to on and dial *67 when I want to block.

    I liked it better the other way.

    My service provider is Sprint and there is NO tab in the phone section of settings for my IPhone 4S to turn off caller ID. Any other suggestions??

    Thanks!

    There is no such option on a Verizon iPhone as ‘Show My Caller ID’, in other words, you cannot turn it off.

    My carrier is sprint and I too do not have the CID in my phone menu and I don’t know is if I have to call sprint or if there’s an easier way so please post an update if any of you find a solution! Thank you!

    Simon, I’m in North America, is there a way to permanently block caller ID & then on a call by call basis unblock so the caller can see the caller ID ONLY for that call?

    Cheers,
    Michael
