This wikiHow teaches you how to call someone without them being able to see your real number. The easiest way to do this on any phone is by dialing a prefix (such as *67 ) before dialing the phone number in question. If you have a smartphone, you may have the option of making all of your outgoing calls anonymous from within the Settings app, though not all phones have this option. Finally, you can use the free Google Voice app to call using a number other than your own, which will protect your true phone number even if the person whom you're calling has a call-unmasking program.

Using a Prefix

  1. To make an anonymous call with a prefix, you'll enter the prefix, enter the ten-digit phone number (or eleven-digit phone number if you're using a country code), and press the "Dial" button. Common prefixes include the following: [1]
    • *67 - Most North American mobile phones and landlines, as well as Canadian landlines. [2]
    • #31# - Some North American mobile phones (i.e., AT&T), and some Canadian mobile phones. [3]
    • 141 - Most UK mobile phones and landlines.
  2. This app usually looks like a phone receiver on a colored background, and is usually found on your smartphone's home screen.
    • If you're using a landline phone or a non-smartphone cellphone, just prepare to dial.

  3. If your smartphone's Phone app doesn't open to a keypad, look for the "Dialpad" icon or tab and then tap it. This icon usually resembles a keypad's shape.
    • Skip this step on landlines and non-smartphone cellphones.
  4. Type in the prefix for your area. For example, if you're dialing from a North American phone, you'll most likely enter *67 .
    • Do not press the "Call" button yet.
  5. Enter the phone number that you want to call anonymously. When done, the whole number should resemble the following: *678085031234
  6. This will call the number in question while masking your number. The recipient will see something like "BLOCKED", "RESTRICTED", or "CALLER ID UNAVAILABLE" on their phone's screen or LCD display.
    • Keep in mind that some people will have call-unmasking apps installed on their phones, meaning that they'll be able to see your number regardless of this prefix. [4]

    • If you aren't signed into Google Voice, select an email account, or enter your email address and password when prompted.
  2. It's a phone receiver-shaped icon at the bottom of the screen (iPhone) or at the top of the screen (Android).
  3. This option is in the lower-right corner of the screen. On iPhone, a pop-out menu will appear.
    • On Android, this button resembles a phone receiver instead.
  4. It's in the pop-out menu. Doing so opens the caller page. [6]
    • Skip this step on Android.
  5. Type in the number of the person whom you want to call anonymously.
  6. This option is in the drop-down menu below the text field that's at the top of the screen.
  7. Doing so will call the number that you selected. Your recipient will be able to see a phone number, but not your actual number.

    A number that cannot be tracked and when using Caller ID does not show up with anything other than "BLOCKED" or "PRIVATE CALLER."

      Warnings

      • Never use anonymous calling to make inappropriate calls to emergency services. Not only does this put people's lives at risk - you can still be tracked down by the police and given large fines or even a jail sentence.
        Thanks

      • Never use anonymous calling to stalk, threaten or harass other people. Even if you try to hide your phone number, the police can still trace abusive calls directly to you.
