How to Temporarily Turn Off iPhone Caller ID to Make a Blocked Call

Nov 3, 2010 - 5 Comments

Phone app You may know that iPhone users can opt to turn off Caller Id on their iPhone to always make blocked calls from that number and phone, this means when your calls will show up as “blocked” to the recipients phone all the time. But you may not want to block every call all the time, and instead you might just want to temporarily block an iPhone call that you’re making.

How to Temporarily Disable Caller ID (for your Number) When Making a Phone Call from iPhone

To temporarily block caller ID and make a per-call “Blocked” call, here’s what you can do on the iPhone (or Android or any other phone):

  1. Go to the Phone app numerical dialer screen
  2. Dial *67 before entering any other number on screen, it must prefix the number you will call
  3. Now enter the phone number as usual to dial, and proceed to call as usual

The number dialed must have *67 as the prefix to block your caller ID for this specific call. For example, if you are calling “1-808-555-1212” then the blocked version would be “*6718085551212”

That call only will appear as blocked, due to the *67 prefix entered. This temporarily disables caller ID on your call so that you can appear as blocked and anonymous.

As mentioned, you can also make all of your outgoing calls appear as “Blocked” on recipients phones by disabling your Caller ID on the iPhone, here’s how.

You can do this with any number, so when you call people from your iPhone and use the *67 prefix, your caller ID will be disabled and your number will appear as “Blocked” rather than a listed name, or a phone number, or contact. This is helpful if you prefer to remain anonymous, or you just don’t like caller ID in general.

Do keep in mind this will only block your caller ID on normal cell phones and land lines, it does not set an anonymous call to public services, which is not possible with *67.

And for what it’s worth, *67 works to dial out anonymous calls on any iPhone, landline, Android, Blackberry, or Windows phone, it is the universal ‘anonymous’ prefix code.

    HELP! I have and iPhone 9 and it has automatically blocked all unknown calls! It sends them to voicemail. Granted this would normally be a great figure if I currently was not looking for work, but I cannot find the setting in the phone app to change it.

    This works. But I’m almost certain that it will not work on calls to toll-free numbers.

  3. Bob says:

    This works on a landline, but it does not work on an iPhone – since it seems you cannot create a pause required after entering *67 and then when asks you (on the landline) to enter the phone number

    I use *67 to make blocked prank calls when I was a kid. But Who does this guy think he is? He is not the originator of this.
