You want to make an anonymous call to somebody but you are not sure how to block your caller id. You can block your caller id by simply pressing #67 before you make a phone call. You’ll hear a series of short tones and then you can make your phone call.

50 percent of the people that see “blocked call” or “private” on their caller id display will not even bother to pick up the phone. The best way to block your number is to disguise your caller id.

It’s easy to make any number you want to appear on a caller id. This way you can make it look like you are calling from another phone number. If you fake your caller id and make it look as if you are calling from a different phone number, more people will answer the phone when you call.
