Blocking stops someone from calling, texting, or reaching you through FaceTime
When you block someone on an iPhone, that person cannot call you, send you text messages, or start a FaceTime call with you. Their calls go straight to voicemail as if your phone is off. Text messages they send do not arrive in your Messages app. If they try to FaceTime you, they will see a message saying the call failed.
The person you block does not receive a notification that you blocked them. However, they may figure it out over time — their calls always go to voicemail, their texts never get a response, and FaceTime calls always fail. There is no way to block someone without them eventually noticing the pattern.
Blocking is different from muting or silencing notifications. If you mute someone, their messages and calls still reach you, but your phone does not alert you. If you block them, the messages and calls do not arrive at all.
Key Takeaways
- Blocking someone prevents their calls, texts, and FaceTime requests from reaching you, and their calls go to voicemail instead.
- You can block a contact through the Phone app, Messages app, or by opening their contact card and scrolling to the Block option.
- Blocked people do not get a notification, but they will notice when calls always go to voicemail and texts never get responses.
- You can unblock someone at any time by finding them in your blocked list and tapping Unblock.
- Blocking someone on one Apple device does not automatically block them on your other devices — you may need to block them separately on iPad or Mac.
How to block someone from the Phone app
Open the Phone app and find the person's number in your recent calls list. Tap the information icon (the small circle with an "i" in it) next to their name or number. Scroll down and tap Block This Caller. A confirmation message will appear — tap Block Contact to confirm.
If the person is in your Contacts, you can also open their contact card directly. Scroll all the way to the bottom and tap Block This Contact. This method works the same way whether you found them through recent calls or through your contacts list.
How to block someone from the Messages app
Open Messages and find the conversation with the person you want to block. Swipe left on their name (or tap and hold on older iPhones). A menu will appear with options including Block. Tap Block and confirm when prompted.
You can also open the conversation, tap Details in the top right corner, scroll down, and tap Block This Caller. Both methods accomplish the same thing — the person will not be able to send you messages or reach you through FaceTime.
How to block someone from their contact card
Open the Contacts app and find the person's name. Tap their contact card to open it. Scroll all the way to the bottom of the card. You will see a red button that says Block This Contact. Tap it and confirm.
This method is useful if you have someone in your contacts but have not recently called or texted them. It is also the clearest way to see exactly who you are blocking before you confirm.
How to see your blocked list and unblock someone
To view everyone you have blocked, open Settings and tap Phone. Scroll down and tap Blocked Contacts. You will see a list of every person you have blocked on this device.
To unblock someone, swipe left on their name in the blocked list and tap Unblock. You can also tap Edit in the top left corner, tap the minus sign next to a name, and then tap Unblock. Once you unblock someone, they can call, text, and FaceTime you again.
What happens when you block someone
When you block someone, their calls go directly to voicemail without your phone ringing. They hear a message saying the call could not be completed. Text messages they send to you do not appear in your Messages app — they straightforward fail to deliver on their end.
If they try to FaceTime you, they will see a message saying the call failed. They cannot see that you blocked them through any of these apps. However, if they try to reach you through multiple methods and everything fails, they will likely realize you have blocked them.
Blocking is one-way. If you block someone, you can still call or text them if you choose to — but most people do not. The block only prevents them from reaching you, not the other way around.
Blocking on multiple devices
If you own an iPad or Mac in addition to your iPhone, blocking someone on your iPhone does not automatically block them on those other devices. You will need to block them separately on each device if you want to block them everywhere.
To block someone on iPad, open Settings, tap Messages or FaceTime, and look for a Blocked option. On Mac, open Messages or FaceTime, find the person's name, right-click, and select Block. The steps vary slightly between devices, but the result is the same — that person cannot reach you on that specific device.
Frequently Asked Questions
Can someone tell if I blocked them?
They do not get a notification, but they will likely figure it out. Their calls always go to voicemail, texts never deliver, and FaceTime calls always fail. After a few attempts, most people realize they have been blocked.
If I block someone, can I still see their old messages?
Yes. Blocking only stops new messages from arriving. All previous conversations with that person remain in your Messages app and you can read them anytime. Unblocking someone does not delete old messages either.
What if I block someone by accident?
Open Settings, tap Phone, tap Blocked Contacts, find the person's name, swipe left, and tap Unblock. They can reach you again when ready. There is no penalty for unblocking — you can block and unblock the same person as many times as you need to.
Does blocking someone delete their contact from my phone?
No. Their contact information stays in your Contacts app. Blocking only prevents them from calling, texting, or FaceTiming you. If you want to remove their contact entirely, you have to delete it separately.
Can I block someone on iMessage but not on regular text?
No. Blocking on iPhone blocks all contact methods at once — calls, text messages, and FaceTime. You cannot block someone for just one type of communication. If you want to avoid their messages but still receive calls, you would need to mute them instead of blocking them.
