People, companies, and solicitors use the restricted call technique to stop being accessible and identifiable. So, nobody can identify their phone number to call them back when they call someone with their restricted number.

They might be doing it for security or privacy reasons. However, some receivers don't feel secure attending a call that has no caller identification. Due to the excess of fraud and harassment incidents, people can't stand unknown or restricted calls on their screens.

The article will teach you how to stop being called by restricted phone numbers. For this cause, we will cover the following topics:

What is a Restricted Call?

A restricted phone call is when someone who does not want to be tracked or exposed calls you. When a restricted number calls you, the actual phone number will not be displayed to you. Instead, the incoming call will appear as “Restricted” on the phone screen.

It means that the caller does not want you to know his phone number. They use the block feature to hide their phone number identity from the public. There are different reasons why someone would restrict their phone number.

Many private agencies and collection companies use the restricted call feature for security reasons. This makes them inaccessible to the public, so they don’t trace their location or call the companies back.

Moreover, companies and some people restrict their phone calls for privacy reasons. This act prevents them from being exposed to solicitors or harassers. By being anonymous, no one can call them back from any phone number. Sometimes, you can try phone number lookup tools before you take the next move.

How to Block Restricted Calls via the Built-in Mobile Feature

We have identified what a restricted call is. Here, we will learn how to block restricted calls with Android and iPhone devices.

Block Restricted Phone Calls on Android

Android is an open operating system (OS). Therefore, some people tend to stay away from unknown calls for their security. One can block all the restricted phone calls on their Android phone with the following procedure:

  • Click on the “Phone” application located on the home screen of your Android phone.
  • Look through all the incoming and outgoing phone calls. Locate the target restricted phone number and click on the question mark situated next to the number.
  • Select the “Block Number” option. Now, you will not receive any call from that number.

Block Restricted Phone Calls on iPhone

The iPhone has two ways to block restricted calls. We will recognize both procedures to stop restricted calls from accessing you.

Blocking a Restricted Number via Call History

  • Head over to the "Phone" application by clicking on its icon.
  • Identify the specific restricted phone number in your call history. Click on the question mark on the number’s left side.
  • Choose the “Block this Number” option to stop the calls from that restricted number.

Blocking the Restricted Number via the "Do Not Disturb" Feature

  • Go to the iPhone general settings. Locate the option of "Do Not Disturb." Further, find the "Allow Call from" option and click on it.

  • After completing the settings, locate and turn on the "Do Not Disturb" mode from the top of the page.

Block Restricted Phone Call via Service Provider
