Are you tired of receiving calls from unknown numbers on your iPhone? Blocking these unwanted calls can help you regain control of your device and protect yourself from unwanted interruptions. In this article, we will guide you through the steps to block unknown numbers on your iPhone.

Method 1: Blocking Unknown Numbers using the Phone App

If you want to block unknown numbers directly from the Phone app, follow these simple steps:

  1. Open the “Phone” app on your iPhone.

  2. Tap on the “Recents” tab at the bottom of the screen.

  3. Scroll down and find the unknown number that you want to block.

  4. Tap on the “i” icon next to the unknown number.

  5. Scroll down and tap on “Block this Caller”.

Note: Blocking a number will also prevent that caller from leaving voicemails. If you have previously received voicemails from an unknown number that you would like to block, it is recommended to save those voicemails before blocking the caller.

Method 2: Blocking Unknown Numbers using Settings

If you prefer to block unknown numbers using your iPhone’s settings, here’s what you need to do:

  1. Go to your iPhone’s “Settings” app.

  2. Scroll down and tap on “Phone”.

  3. Select “Blocked Contacts”.

  4. Tap on “Add New..”

  5. Type the unknown number you want to block and tap “Block this Caller”.

Note: You can also block unknown numbers from your iPhone’s “Messages” app by following a similar process. Open the “Messages” app, tap on the conversation with the unknown number, tap on the contact’s name or number at the top of the screen, scroll down, and select “Block this Caller”.

Method 3: Using Third-Party Call Blocking Apps

If you receive a large volume of unwanted calls or want more advanced call blocking features, you can consider using third-party call blocking apps available on the App Store. Some popular options include Truecaller, Hiya, and RoboKiller.


Blocking unknown numbers on your iPhone is a simple yet effective way to prevent unwanted calls and maintain your peace of mind. Whether you choose to block numbers directly from the Phone app or through your device settings, taking control of your incoming calls is just a few taps away.

Remember to stay vigilant while sharing your phone number online and report any harassing or scam calls to your local authorities if necessary.
