How to Block a Phone Number on iPhone

Using Settings

Open Settings, which is a gray gear icon (⚙️) and usually appears on the home screen.

Tap Phone . This application is often grouped with other Apple applications such as Mail and Notes.

Tap Call Blocking & Identification in the "CALLS" section of the menu.

A list of all contacts and anonymous numbers that you have previously blocked will be displayed.

Scroll down the list and select Block Contact at the bottom of the screen.

If the list of blocked callers exceeds the screen, you will have to scroll down.

Select the contact to block. You'll do this by tapping on the name of the person you want to block. Thus, this number will not be able to contact your iPhone by call, FaceTime or text message.

Repeat the previous two steps for all anonymous numbers or contacts you want to block.

You can unblock numbers from this menu by tapping Edit in the top right corner of the screen and selecting the number.

Block all calls

Open Settings, the gray gear icon (⚙️), usually shown on the home screen.

Tap Do Not Disturb . It's near the top of the menu, next to the moon icon on a purple background.
