Block Caller ID on iPhone to Always Make “Blocked” Calls

Nov 20, 2011 - 13 Comments

Always Make Blocked Calls from iPhone

The iPhone can be set to always hide the dialing phones number from the recipients caller ID’s. This works by initiating every phone call with the prefix *67 to force the number to appear as “Blocked” on the receiving caller ID. This is helpful for making anonymous phone calls, or if you just want to be sent to someones voicemail.

  • Launch “Settings” and tap on “Phone”
  • Tap on “Show My Caller ID”
  • Slide to “OFF”

You can also manually prefix a number with *67 when dialing to make a one-off call that is blocked from caller ID. Generally speaking nobody likes receiving “Blocked” calls, so if you want your phone calls to be answered it’s a good idea to leave the iPhone’s Caller ID enabled.

    check the GPS feature in your phone. If it’s on, it’s burning battery.

    You can also dial *67 before the number to block on a call by call basis.

    My 4s (Verizon) does not have this setting. Not that it’s a big deal but is this a carrier specific feature?

    Hey there brainiacs. This only blocks ID to your friends and relatives, etc. By law, any 800, 888, 900, etc. number will be allowed to see your Caller ID. Duh.

    Sprint services for the iPhone also does not have this feature. It appears that only iPhones carried by AT&T has this setting. When I changed to Sprint from AT&T, that was one of the first things that I noticed.

  12. [...] From a callers perspective, nothing is different, but your iPhone will no longer ring and instead it will just send the calls off to the number you specified. You can still make phone calls as usual with forwarding on, but return calls will not come back to your phone number even though that number remains on caller id. [...]
