It is also a good idea to call a number where you need to dial in the area code. When dialing in the area code you will follow the same step above. first dial *67 then 1 + the area code + the number.

Your other option is to have your number permanently blocked from showing up on any caller ID. You can do on either a land line or a cell phone. Simply call your service provider and ask specifically to have your number blocked or flagged as private. By doing this your number will come up as a private number on any caller ID.

But there are situations when you want your number to show on someone's caller ID; you still have this option. When you have a permanently blocked number, you can unblock it by dialing 82 before placing the call.
