What do you dial to block your phone number when making a call?

In order to make a phone number show up as blocked, it is necessary for a person to dial *67 before he or she dials the intended recipient's phone number. The *67 tool is a free feature that blocks the caller's phone number for a single call.

Individuals can request that a phone number permanently show up as blocked by contacting his or her phone company. If there is an instance when a person needs the phone number to be displayed, dialing *82 before inputting the recipient's number allows the number to come up. Federal Communications Commission rules require that phone companies offer the *67 and *82 features free of charge for interstate telephone calls.
