Step by Step Tutorial

Before we jump into the steps, let’s clarify what we’re aiming to achieve. Following this tutorial, you’ll be able to block any number that’s bothering you, ensuring they can’t contact you via call, message, or FaceTime.

Step 1: Open the Phone App

Start by opening the Phone app on your iPhone 15.

The Phone app is where all your call logs are stored. It’s the green icon with a white phone receiver that you likely use daily.

Step 2: Find the Number

Locate the number you want to block in your recent calls or contacts.

You can either scroll through your recent calls or if the number is saved in your contacts, you can find it there.

Step 3: Tap on the “i” Icon

Tap on the “i” icon next to the number you want to block.

The “i” icon provides more information about the call or contact, including the option to block the number.

Step 4: Scroll Down and Select “Block this Caller”

Once you tap on the “i” icon, scroll down and find the “Block this Caller” option.

The “Block this Caller” option is usually towards the bottom of the screen, so you might need to scroll a bit to find it.

Step 5: Confirm Your Choice

Tap “Block this Caller” and then confirm your decision to block the number.

A pop-up window will appear asking you to confirm that you want to block the number. Once you tap “Block Contact,” the number will be added to your blocked list.


PrivacyBlocking a number on your iPhone 15 ensures your privacy is protected from unwanted callers.
ConvenienceIt takes only a few taps to block a number, making it a convenient feature to use anytime.
Peace of MindKnowing that a particular number can no longer disturb you provides peace of mind.

Blocking a number provides an added layer of privacy, as you can prevent specific contacts from reaching you. This is particularly useful if you’re dealing with harassment or just want to avoid distractions.

The convenience of blocking a number directly from your call log or contact list makes it an easy and accessible feature for users of all ages and tech-savviness. It’s designed to be user-friendly and quick.

Having the ability to block a number can offer significant peace of mind, especially if the calls or messages were causing stress or anxiety. Once a number is blocked, you no longer have to worry about it.


Missed Important CallsYou might accidentally block a number that’s important and miss crucial calls.
Not FoolproofSome telemarketers may use different numbers, so blocking one might not stop the calls.
Can’t Block Unknown NumbersThe iPhone 15 does not allow you to block calls from numbers that are not in your contacts or recent calls.

Blocking a number could lead to missing important calls if done inadvertently. Always double-check that the number you’re blocking is indeed one you no longer wish to hear from.

Telemarketers and spammers often use multiple numbers or spoofing techniques. Blocking one number may not fully stop them from contacting you, but it’s a good start.

Unfortunately, you can’t block unknown numbers or private callers directly, as you need to have the number listed in your contacts or call log to block it. This can be frustrating if you frequently receive calls from hidden numbers.

Additional Information

While blocking a number on your iPhone 15 is quite straightforward, there are a few additional things you should keep in mind. First, the blocked number won’t be notified that they’ve been blocked. They’ll simply be sent to voicemail if they try to call you. However, you won’t receive any voicemail notifications either, so it’s as if they never called. Also, if you change your mind, you can unblock a number just as easily as you blocked it. Simply go to your settings, navigate to the ‘Phone’ section, and you’ll find your block list there.

Another point worth noting is that blocking a number on your iPhone 15 doesn’t block them on other Apple devices unless you have iCloud enabled. If you do, your block list will sync across all your Apple devices, saving you from having to block the same number multiple times. This feature is particularly helpful for those who use multiple devices throughout the day.

Lastly, remember that if you’re blocking a number because of harassment or threats, you can and should report it to your local authorities or your mobile carrier. They may be able to offer additional support or take further action.


  1. Open the Phone app.
  2. Find and tap the number.
