Blocking stops calls, texts, and FaceTime from a specific person

When you block a contact on an iPhone, that person cannot call you, send you text messages, or reach you through FaceTime. Their calls go straight to voicemail as if your phone is off. Text messages from them do not arrive. If they try FaceTime, they see a message saying the call failed. You can block someone in under a minute from your Contacts app, Messages app, or Phone app — whichever one you happen to be using when you decide to block them.

Blocking is different from muting notifications. If you mute someone, their messages and calls still come through, but your phone does not alert you. Blocking stops the contact entirely. The blocked person does not get a notification that you blocked them, but they will notice they cannot reach you.

Key Takeaways

  • You can block a contact from the Contacts app, Messages app, Phone app, or FaceTime app — each method takes about 30 seconds.
  • A blocked person's calls go to voicemail, texts do not arrive, and FaceTime calls fail without notifying them they are blocked.
  • You can unblock someone at any time by finding them in your blocked list and tapping Unblock.
  • Blocking only works on your device — if the person calls from a different number or uses a different service, they can still reach you.

Block someone from your Contacts app

Open the Contacts app on your home screen. Find the person you want to block by scrolling or using the search bar at the top. Tap their name to open their contact card.

Scroll to the bottom of the contact card and tap the red button that says "Block this Caller." A popup will appear asking you to confirm. Tap "Block Contact" to finish. The person is now blocked and cannot reach you through calls, texts, or FaceTime.

Block someone from Messages or Phone

If you are already texting or calling with someone, you do not need to go to Contacts. Open the Messages app and find the conversation with the person you want to block. Press and hold on their name or the conversation thread until a menu appears. Tap "Block this Caller."

The same method works in the Phone app. Open Phone, go to the Recents tab, find the person's name, swipe left on it, and tap the block icon (a circle with a slash through it). Confirm when the popup appears. The contact is blocked when ready.

Block someone from FaceTime

Open FaceTime and find the person in your recent calls or contacts. Press and hold their name until a menu appears. Tap "Block this Caller." This prevents them from reaching you through FaceTime on any of your Apple devices.

You can also open their contact card in the Contacts app and scroll down to block them from there. Either method blocks them across all services — calls, texts, and FaceTime.

Where to find your blocked list

To see everyone you have blocked, open Settings and scroll down to find the app you used to block them — Phone, Messages, or FaceTime. Tap that app, then look for "Blocked Contacts" or "Blocked" in the menu. Your full blocked list appears there.

From this list, you can unblock anyone by tapping "Edit" in the top right corner, then tapping the minus sign next to their name. Tap "Unblock" to confirm. Once unblocked, they can call, text, or FaceTime you again.

What happens when you block someone

A blocked person's calls go directly to voicemail. They hear your voicemail greeting and can leave a message, but you will not be notified that they called. Text messages from them do not appear in your Messages app at all — they straightforward do not arrive on your phone. If they try to FaceTime you, they see a message saying the call failed.

The blocked person does not receive a notification saying they are blocked. They only realize it when they notice they cannot reach you across multiple attempts. Blocking does not delete past conversations — old texts and call history with that person remain in your phone unless you delete them manually.

Blocking does not work across all services

Blocking only affects the phone number or Apple ID you blocked. If the person calls from a different number, your iPhone will not recognize it as the same person and the call will come through. If they contact you through email, social media, or another app, blocking them on iPhone does not stop those messages.

If someone keeps contacting you from new numbers after you block them, that is harassment. You can report the behavior to your carrier or to local police. Some carriers offer tools to block multiple numbers at once or to filter calls by type.

Frequently Asked Questions

Can a blocked person see that I blocked them?

No. They do not get a notification. They only realize it when they try to call or text and notice the calls go to voicemail and texts do not get responses. After several attempts, they may figure out they are blocked.

Will a blocked person see my old text messages?

No. Once you block them, they cannot see any of your messages — old or new. On their end, the conversation may still appear in their Messages app, but any new messages you send will not go through.

Can I block someone without them knowing?

Yes. Blocking is silent — they do not get a notification. They will only realize it when they try to reach you and cannot. There is no way for them to know the exact moment you blocked them.

What if I block someone by accident?

Go to Settings, find the app where you blocked them (Phone, Messages, or FaceTime), tap "Blocked Contacts," tap "Edit," and tap the minus sign next to their name. Tap "Unblock" to restore contact.

Does blocking someone delete our conversation history?

No. Your old messages and call history with that person stay on your phone. Blocking only stops new messages and calls from reaching you. You can delete the conversation manually if you want to remove it.
