What are the Reasons for Anonymous Calling?

There are various reasons for anonymous calling. Obviously, bad intentions aren’t our cup of tea, so we’ll only focus on the genuine reasons to make an anonymous phone call.

  3. Using it for online account verification.
  4. Verifying someone’s identity without revealing yours.
  5. Using it during data breaches, security hacks, and government surveillance abound.

Now that you know some fundamental reasons to call someone anonymously, your next big question must be how to call anonymously.

To make an anonymous call using a prefix, you’ll need to enter the prefix followed by the ten-digit phone number/eleven-digit phone number if you use the country code. Then, you need to press the dial button to start your anonymous call.

Some common prefixes include:

  • *67- Most North American mobile phones, landlines, and Canadian landlines use this prefix.
  • #31#- Some North American mobile phones (AT & T) and some Canadian mobile phones use this prefix.
  • 141- Most UK mobile phones and landlines use this prefix. 

Open your Smartphone’s Phone App

The app looks like a phone receiver on a colored background and is mainly found on your smartphone’s home screen. 

  • If you are using a simple cell phone or a landline phone, you must prepare to dial. 

Tap the Dialpad Icon

If your smartphone’s phone app doesn’t open a keypad, search for the Dialpad icon and tap on it. The icon mostly resembles the shape of a keypad. 

  • Skip this step on a simple cell phone and landline. 

Enter your Prefix

Now, type the prefix of your area. For example, if you are dialing from a North American phone, you are mostly like to enter *67. 

  • Don’t press the call button.

Type the Number

Type the number that you want to make an anonymous call to. When done, the whole number must resemble the following: *678098657890.

Press the Call Button

When you press the call button, you can call the number in question while masking your number. The recipient will see something like “caller id unavailable” or “restricted” on their Phone’s screen. 

  • Keep a note that many people have unmasking apps installed on their phones. It means those people will be able to see your number even with the prefix.
