How to Call Anonymously

This wikiHow teaches you how to call someone without showing your real phone number. The easiest way is to dial the blocking code (such as *67 ) before the phone number to call. ^{[1] X Research Source} If you use a smartphone, the Settings app will have the option to set all outgoing calls to anonymous. Otherwise, you can use the free Google Voice app to call with another number, your real number will be safe even if the recipient uses a caller ID retrieval program.

Define blocking code. To make a hidden call with a block code, you need to enter the code before 10 phone numbers (or 11 if you use a country code) and press the call button. Here are some common blocking codes: ^{[2] X Research Source}

*67 – For most mobile and landlines in North America, as well as landlines in Canada.
#31# – For some North American mobile phones (such as AT&T) and Canada.
141 – For most mobile and landline phones in the UK.

Open the Phone app. This application usually has a phone receiver on a colored background and is located on the home screen of the smartphone.

If you have a landline or feature phone just pick up and dial.

Press the call button. The call will be made and your number will be hidden. The recipient will see the ID as “BLOCKED” (blocked), “RESTRICTED” (restricted) or “CALLER ID UNAVAILABLE” (caller name not available) displayed on the LCD or touch screen of the phone.
