You can block texts from specific people directly in the Messages app

iPhone gives you two straightforward ways to stop text messages from reaching you. The fastest method is to block someone right from a conversation thread — you tap their name, then tap Block This Caller. The second way is through your iPhone's settings, where you can manage a full list of blocked contacts. Both methods work the same way: blocked people can still send you texts, but the messages never arrive on your phone, and they won't see a delivery notification.

The person you block will not receive a message saying they're blocked. They'll only notice if they try to call you afterward — your phone will go straight to voicemail without ringing. Text messages simply disappear into nothing on their end.

Key Takeaways

  • You can block someone from any text conversation by tapping their name and selecting Block This Caller.
  • Blocked texts never reach your phone, and the sender won't know they've been blocked through texting alone.
  • You can see your full list of blocked contacts in Settings under Phone, Messages, or FaceTime depending on how they contacted you.
  • Unblocking someone is just as simple — go to Settings, find the person's name in your blocked list, and tap Unblock.
  • Blocking someone in Messages does not automatically block them in Phone calls or FaceTime, so you may need to block them in multiple places.

Block someone directly from a text conversation

Open the Messages app and find the conversation with the person you want to block. Tap their name or number at the very top of the conversation thread — you'll see it displayed above all the messages. A small menu will pop up showing their contact card.

Look for the info icon (a small circle with an "i" inside) and tap it. Scroll down until you see the Block This Caller option, then tap it. A confirmation message will appear asking if you're sure — tap Block Contact to confirm. That person's future texts will no longer reach your phone.

Block someone through your iPhone settings

If you don't have an active conversation with someone, or you prefer to manage blocks from one central location, use the Settings app. Open Settings and scroll down to find either Phone, Messages, or FaceTime — the location depends on which service you want to block them from. Tap the one you need.

Look for an option called Blocked Contacts or Block List (the exact name varies slightly by iOS version). Tap Edit in the top right corner, then tap the plus sign to add a new blocked contact. Search for the person's name or number and tap their contact to add them. If you don't have them saved as a contact, you can type their phone number directly.

The difference between blocking in Messages, Phone, and FaceTime

iPhone treats Messages, Phone calls, and FaceTime as separate services. Blocking someone in Messages stops their texts, but they can still call you or reach you on FaceTime unless you block them there too. The same applies in reverse — blocking them from calling doesn't block their texts.

If someone is harassing you across multiple services, you'll need to block them in each one separately. Go to Settings, then Phone, and add them to the Phone blocked list. Then go to Settings, Messages, and add them there too. Then do the same in FaceTime if needed. It takes a few extra taps, but it closes all the doors.

How to unblock someone

Open Settings and go to Phone, Messages, or FaceTime — whichever service you blocked them from. Tap Blocked Contacts or Block List. Find the person's name in the list and swipe left on it, or tap Edit and then the minus sign next to their name. Tap Unblock to confirm.

Once you unblock them, their messages and calls will come through normally again. They won't be notified that you've unblocked them. If they sent you texts while they were blocked, those messages will not suddenly appear — they're gone permanently.

What happens when you block someone

When you block someone in Messages, their texts go nowhere. They won't see a delivery notification, and you won't see their messages. Your phone simply ignores them. If they try to call you, the call goes straight to voicemail, and they won't hear a busy signal or any indication that you've blocked them — it will just ring once or twice and then go to voicemail.

Blocked people can still see your profile picture and status on iMessage if they're using an iPhone, but they won't be able to message you or see when you're typing. If they contact you from a different phone number or account, those messages will come through normally — blocking only applies to the specific contact you blocked.

Blocking spam and unknown numbers

If you're getting texts from numbers you don't recognize, you can block them the same way. Open the conversation, tap the number at the top, tap the info icon, and select Block This Caller. You can also report the message as spam at the same time — tap Report Junk before you block, and Apple will use that information to improve its spam filters.

For ongoing spam, consider enabling Filter Unknown Senders in Settings. Go to Messages, scroll down, and toggle on Filter Unknown Senders. This moves texts from people not in your contacts to a separate tab, so they don't clutter your main inbox. You can still see them if you need to, but they won't interrupt you with notifications.

Frequently Asked Questions

Will the person know I blocked them?

They won't know through texting. Their messages will simply fail to deliver with no notification on their end. If they try to call you, they'll notice the call goes straight to voicemail, which might tip them off, but texting alone won't reveal that you've blocked them.

Can I block someone and still see their old messages?

Yes. Blocking only stops new messages from arriving. All the old texts in that conversation stay on your phone. If you want to delete them, you can swipe left on the conversation and tap Delete, but that's a separate action from blocking.

What if someone blocks me — will I know?

You might notice if your calls go straight to voicemail repeatedly, or if you send several texts and never get a response. There's no official notification, but the pattern usually becomes obvious after a few attempts to contact them.

Can I block someone on iMessage but not regular SMS?

No. When you block someone in Messages, it blocks both iMessage and regular SMS from that contact. You can't split the block between the two services — it's all or nothing in the Messages app.

Do blocked messages take up storage space on my phone?

No. Blocked messages never reach your phone, so they don't use any storage. They disappear on the sender's end without ever being stored on your device.
