If you’re tired of unwanted calls, spam texts, or persistent telemarketers, your iPhone makes it incredibly easy to block them. Apple’s built-in blocking feature sends calls straight to voicemail, hides text messages, and stops FaceTime requests — giving you complete peace and quiet.
In this guide, you’ll learn how to add a number to your iPhone block list using different methods, including the Phone app, Messages app, Contacts, and Settings. Everything is explained in clear steps so you can block anyone in seconds.
Why Block a Number on an iPhone?
Blocking a number helps you:
-
Stop spam or robocalls
-
Avoid unwanted text messages
-
Prevent harassment or disturbance
-
Keep your privacy protected
-
Gain more control over who can contact you
Once blocked, the person cannot call, text, or FaceTime you — and you won’t receive any notifications from them.
How to Add Someone to the iPhone Block Number List
There are three easy ways to block someone on an iPhone. You can block them through the Phone app, Messages app, or directly from your Contacts list.
Method 1: Block a Number Through the Phone App
This is the fastest way if someone recently called you.
Steps:
-
Open the Phone app on your iPhone.
-
Tap the Recents tab at the bottom.
-
Find the number you want to block.
-
Tap the (i) info button next to the number.
-
Scroll down and select Block this Caller.
-
Confirm by tapping Block Contact.
That’s it — the number is now on your block list.
Method 2: Block Someone From the Messages App
If someone is sending annoying or spam texts, use this method.
Steps:
-
Open the Messages app.
-
Tap the conversation from the number you want to block.
-
Tap the contact name or number at the top.
-
Tap the info (i) button.
-
Scroll down and select Block this Caller.
-
Confirm with Block Contact.
The person will no longer be able to message you.
Method 3: Add Someone to Block List From Contacts
If the number is saved in your phone, block them directly through Contacts.
Steps:
-
Open the Phone or Contacts app.
-
Choose the contact you want to block.
-
Scroll to the bottom of the contact info.
-
Tap Block this Caller.
-
Confirm with Block Contact.
This method works great for blocking someone you already know.
How to View or Unblock Numbers on iPhone
If you ever need to manage or unblock someone:
Steps:
-
Open Settings.
-
Scroll down and tap Phone.
-
Tap Blocked Contacts.
-
You’ll see your full block list.
-
Tap Edit to remove anyone.
This helps you stay in full control of your blocked numbers.
What Happens After You Block Someone?
Blocking prevents:
-
Phone calls
-
Text messages
-
FaceTime audio/video
The blocked person will not know they are blocked. Calls go to voicemail silently, and texts never appear on your device.

Adding someone to the iPhone block number list is quick, simple, and extremely helpful for getting rid of spam or unwanted communication. Whether the number is saved in your contacts or just appeared in your recent calls, blocking takes only a few taps.
