When you want to block your number, you must first determine if you want the block to be permanent or if you would only want your number to be block to specific people only. To block only specific persons, there are codes that you have to enter when making your number appear as blocked to the person you are calling, which you must always remember when making a call. However, if you have trouble memorizing codes, then the permanent solution would be much more suitable for you.

To make your number blocked from all caller IDs, you must call your phone company and tell them your intentions. Tell them that you want to Block Caller ID and you want this to be effective to all of your outgoing calls. Your phone company will then change their systems to not to identify the number the call is originating from to the person you are calling. However, keep in mind that there may be additional charges for this kind of service. Some may charge fees, while some may not; it really depends on the company.

To Block Caller ID, you must enter a code, which varies from country to country, before entering the phone number you are going to call. However, remember that this will not work to toll-free numbers. Also, emergency call services will show the phone number in where the call is coming from.

There are also other ways to Block Caller ID nowadays. You just have to search them on the net. And always remember to ask if there will be additional charges, to avoid unexpected charges on your phone bill.
