When you block your Caller ID (which is your number), your number will be masked and won’t be displayed on the recipient’s device. Instead of your number, the recipient’s device will say “No Caller ID,” “Blocked,” “Unknown,” or “Private Number” as the caller. So, the recipient won’t know who is calling until the phone call is answered. On your iPhone, you can hide your Caller ID either temporarily or permanently. You can hide your number temporarily using *67. When you hide your number, the other person will see a screen like this:
You may want to hide your Caller ID so that people won’t see your mobile number for a variety of reasons. For example, you may be a celebrity, and you want to call a fan, but you do not want to give away your number. Or, your number may be blocked by the other person, and you are trying to hide your number to overcome this blocked situation. These may be unique circumstances, but everyone has their reasons to block their Caller ID to prevent the people you call from seeing their number.
Use keypad to turn off Caller ID and hide your number
This is a neat tip. This enables you to quickly and temporarily hide your Caller ID. Of course, you can go to Settings > Phone > Show My Caller ID to turn off and on Caller ID. If you turn off Caller ID using this method, your Caller ID will be hidden for all of your calls from that moment on until again you turn it on. But this may not be ideal for most people. Most people may only want to hide their Caller ID in certain circumstances. The solution is to use the *67 when calling. This will only hide your Caller ID for this specific call. Here is how:
- Open the Phone app on your iPhone.
- Tap the Keypad tab.
- Enter *67 and the number you wish to call, the full ten-digit phone number. You will need to enter the area code as well, like below. Then hit the green call button to make the call. And your number will not be shown.
One negative thing about this is that you cannot just open your contacts and tap a contact to make a call. You will need to enter the number. You can do that easily if you know the number by heart. But most people do not memorize the numbers. What you can do is first find the contact in Contacts within the Phone app and then tap Keypad, and switch back and forth as many times as necessary to enter the number.
*67 is a cellular feature, not a phone feature. If it is not working for you, that is because (a) you did not do it correctly or (b) your carrier does not support this feature. This also means that this should work regardless of your platform or device type, like Android, iOS and more, even non-smartphones.
