The ‘*67’ feature is also called the vertical service code. Some providers require you to wait until you hear the dial tone after entering a code before entering the rest of the number. Your number will be displayed on the recipient’s screen. So, instead of navigating through the settings to enable the feature and then disabling it again after the call, just dial ‘*82’ and the desired phone number. If you want your ID to remain hidden, but you want to make a transparent call, there’s also a code you can type prior to the number.

If you want to make your ID visible again, just follow the same steps and select ‘Network default’ or ‘Show number’ instead.

But this facility is not available with all the service providers. Most users can also block their numbers themselves by changing a few settings on their mobile phones. Moreover, some phones are programmed in a manner that they do not accept calls from blocked numbers. However, it is important to note that you cannot block your caller ID when you are calling 911 or 800 numbers. The number will be automatically blocked when you call that contact from now on. In case you want to permanently block your number, then add that number as a contact and save it with *67 at the start.
