When setting up your new smartphone, you mainly use your real name and information. And due to this, the phone numbers can be traced to their owners. But what if you want to make an anonymous call without letting the person know your private number?
This is where an anonymous phone number comes in handy. Learn about anonymous calls, the reasons for anonymous calling, and how to call someone anonymously with us.

What is an Anonymous Phone Call?

An anonymous phone call is a type of phone call that blocks caller ID to hide your phone number when you make a call.

Anonymous Calls


By blocking the caller ID, your number appears unknown or private on the other phone. You can make anonymous calls to anyone when you don’t want to reveal your identity. Moreover, with an anonymous call, the person you called cannot call you back.    

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.

Reasons for Calling Anonymously


Some of the crucial reasons for making an anonymous phone call include the following:

  1. Calling someone to verify their identity without revealing yours
  2. Providing valuable information to government officials while staying anonymous.
  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 know how to make an anonymous call, take a look at the steps below.

How to Make an Anonymous Call?

If you want to know how to call anonymously, these four methods will help you.

How to make an anonymous call?


Using a Prefix

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.

Using a Prefix


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.
