Step by Step Tutorial on How to Block a Number on iPhone 15

Before jumping into the steps, it’s important to understand that once you block a number, you restrict that number from making calls, sending text messages, or initiating FaceTime sessions with you.

Step 1: Open the Phone App

Open the Phone app on your iPhone 15.

The Phone app is your gateway to all things call-related on your iPhone 15. It’s where your contacts, recent calls, voicemail, and keypad reside. It’s typically located on your home screen for easy access.

Step 2: Locate the Number

Find the number you wish to block in your recent calls or contacts.

If the number you want to block has recently called you, it’ll be in your “Recents” tab. If it’s someone you’ve saved to your contacts, you’ll find them there. If you can’t find them, you can also enter the number manually by tapping the “Contacts” tab and selecting the “+” to add a new contact, where you can then block them.

Step 3: Tap on “info”

Tap on the “info” button next to the number.

The “info” button is denoted by a small “i” inside a circle. It’s your portal to more information about the call or contact, including the option to block them.

Step 4: Select “Block this Caller”

Scroll down and tap on “Block this Caller.”

Once you’re in the info section, scroll down to find the “Block this Caller” option. It’s usually near the bottom, so you might have to scroll a bit.

Step 5: Confirm Your Choice

Confirm you want to block the number.

Additional Information

When you decide to block a number on your iPhone 15, it’s also worth noting that the blocked number is added to a blacklist across all your Apple devices if they’re connected with the same Apple ID. This means that if you block a contact on your iPhone, they’re also blocked on your iPad, iPod touch, and even Mac.

There are alternative methods to block a number besides the Phone app. For instance, if you’ve received a text message from an unwanted number, you can block it directly from the Messages app. Similarly, you can block a caller from your FaceTime log. This interconnectedness ensures that once a number is blocked, it’s really blocked from all angles.

Of course, if you ever change your mind about a blocked contact, you can always navigate back to your settings to unblock them. Just go to Settings, tap on Phone, select Call Blocking & Identification, and you’ll see your list of blocked numbers. From there, you can swipe left on any number to unblock it.
