Block a number directly from a text message

The fastest way to block someone is to open the text thread from that person, tap the phone number or contact name at the top of the screen, then scroll down and tap Block this Caller. Confirm by tapping Block Contact. That person's texts will stop arriving immediately, and any messages already from them will stay in your conversation thread but won't trigger notifications.

If you want to block someone but keep their messages visible for your own records, this method works — the texts remain in your phone but you won't see alerts when new ones arrive. If you change your mind later, you can unblock them the same way: open their contact, tap the number at the top, scroll down, and tap Unblock this Caller.

Key Takeaways

  • You can block a number directly from any text conversation by tapping the contact name at the top and selecting Block this Caller.
  • Blocked texts still arrive on Apple's servers but your phone will not download or show them, and you will not receive notifications.
  • Messages from blocked contacts remain in your conversation thread unless you manually delete them.
  • You can block up to 1,000 numbers on a single iPhone, and the block list syncs across all your Apple devices if you use the same iCloud account.

Block a contact from the Contacts app

Open the Contacts app, find the person you want to block, and tap Edit in the top right corner. Scroll to the bottom and tap Block this Contact, then confirm. This method works the same way as blocking from a text thread — the person's messages stop arriving — but it's useful if you want to block someone before they text you, or if you've already deleted their conversation.

Blocking through Contacts also blocks their calls and FaceTime requests at the same time, so you won't hear from them through any of those channels. If the person is not yet in your Contacts, you can still block their number by opening Settings, going to Messages, tapping Blocked Contacts, and tapping Add New to enter their number manually.

Where blocked messages go

When you block a number, that person's texts still reach Apple's servers, but your iPhone will not download them or show them to you. You won't see a notification, and the message won't appear in your Messages app. The blocked person won't know they're blocked — they'll see their message send normally, with no error or delivery failure.

If you later unblock the number, you won't receive the messages they sent while you had them blocked. Those texts are deleted from Apple's system after a certain period. Your own messages to them are not affected by blocking — they can still see anything you sent before or after the block was in place.

Check and manage your blocked list

To see everyone you've blocked, open Settings, tap Messages, then tap Blocked Contacts. You'll see a list of every number and contact you've blocked through Messages. To unblock someone, swipe left on their name and tap Unblock, or tap Edit and then the red minus sign next to their name.

If you've blocked someone through the Phone app (to stop their calls), they will also appear in this list. Blocking is not app-specific — when you block a number, it blocks them across Messages, Phone, and FaceTime all at once. You can block up to 1,000 numbers on a single device.

Blocked contacts sync across your devices

If you use the same iCloud account on multiple Apple devices — an iPad, Mac, or another iPhone — your blocked list syncs automatically. Block someone on your iPhone and they'll be blocked on your iPad too. This sync happens within a few minutes of you making the change.

If you have a family member who shares an iCloud account with you, they will see your blocked list and you will see theirs. If you want to block someone on just one device without affecting the others, you'll need to use a separate iCloud account on that device, which is not practical for most people. The simpler approach is to manage blocks on whichever device you use most often and let them sync.

What happens when you block someone

Blocking stops text messages, calls, and FaceTime requests from that person. They can still leave voicemails if you have voicemail set up, but you won't be notified about them — you'd have to check your voicemail manually to hear it. They can still see your iCloud status (like whether you're online in Messages) unless you've also turned off that setting in your privacy options.

The person you block won't receive a notification that you've blocked them. Their texts will appear to send normally. If they call you, they'll hear a ring tone but the call won't reach your phone. Some people may figure out they're blocked if they notice you're never responding and their calls always go to voicemail, but there's no official "you've been blocked" message.

Frequently Asked Questions

Can I block someone without deleting our text conversation?

Yes. When you block a number, the entire conversation thread stays in your Messages app. You can still read old messages from that person, but new texts from them won't arrive. If you want to hide the conversation from view, you can swipe left on it and tap Hide, which removes it from your main message list without deleting it.

What if someone texts me from a different number after I block them?

Blocking only affects the specific number you blocked. If the person texts from a different phone or a texting app that uses a different number, those messages will come through normally. You would need to block each number separately. There's no way to block all messages from a person across every possible number they might use.

Will the person know I blocked them?

They won't receive a notification. Their texts will appear to send successfully, and calls will seem to ring normally. However, if they notice you never respond and your status never changes, they may suspect you've blocked them. There's no official way for them to confirm it through the iPhone.

Can I block text messages but still receive calls from someone?

No. Blocking a contact blocks them across Messages, Phone, and FaceTime all together. You cannot block just texts while allowing calls. If you need to receive calls from someone but don't want their texts, you would need to use a different method, like creating a contact with a silent ringtone and turning off notifications for their messages.

What if I accidentally block someone?

Open Settings, tap Messages, tap Blocked Contacts, find the person's name, and tap Edit followed by the red minus sign, or swipe left and tap Unblock. They'll be unblocked immediately, and any messages they send after that point will come through normally. Messages they sent while blocked will not be delivered retroactively.
