Block a specific number or contact on iPhone
You can block individual phone numbers or contacts directly in the Messages app or through your phone settings. The blocked person can still call and text you, but their messages won't show up in your inbox, and they won't get a delivery confirmation when they text you.
To block someone in Messages, open the app and find a text from the person you want to block. Press and hold the conversation, then tap "Block this Caller" from the menu that appears. On iOS 17 and later, you can also swipe left on the conversation and tap the block icon.
If you want to block someone who hasn't texted you yet, go to Settings > Messages > Blocked Contacts and tap "Add New." Then search for and select the contact. You can also block a number directly from the Phone app by finding the contact, tapping the info icon, scrolling down, and selecting "Block this Caller."
Key Takeaways
- Blocked contacts can still call and text you, but their messages won't appear in your inbox and they won't see delivery confirmations.
- You can block someone in the Messages app by holding their conversation and tapping "Block this Caller," or through Settings > Messages > Blocked Contacts.
- Blocking is not the same as reporting spam — you can report a number as spam without blocking it, which helps Apple identify patterns of abuse.
- If you block someone and later unblock them, old messages from before the block won't reappear unless you manually restore them from backup.
- Unknown senders and spam can be filtered separately from blocked contacts using the "Filter Unknown Senders" toggle in Messages settings.
The difference between blocking and reporting spam
Blocking stops one person from reaching you. Reporting spam tells Apple that a number is being used to send unwanted messages, which helps the company identify patterns and protect other users. You can do both, or just one.
To report a message as spam without blocking, open the conversation in Messages, press and hold the message itself (not the whole conversation), and tap "Report Junk." This sends a copy of the message to Apple's spam detection system. The message stays in your inbox unless you delete it manually.
If you want to block and report at the same time, tap "Block this Caller" first, then go back and report the message as junk. Both actions together give you the most protection: the person is blocked from reaching you, and Apple gets data about the spam pattern.
Using filters to hide unknown senders and spam
Even without blocking individual numbers, you can hide entire categories of messages. The "Filter Unknown Senders" setting moves texts from people not in your contacts into a separate tab, keeping your main inbox clean.
Turn this on in Settings > Messages, then toggle "Filter Unknown Senders" to on. Messages from contacts in your phone will still arrive in your main inbox. Everything else — including texts from unknown numbers, businesses you've never interacted with, and spam — goes to a separate "Unknown Senders" tab that you can check when you want to.
This is useful if you don't want to block specific numbers but also don't want random texts cluttering your main conversation list. You can still read messages in the Unknown Senders tab if something important comes through, and you can block or report individual messages from there.
Managing your blocked contacts list
You can see everyone you've blocked and unblock them anytime. Go to Settings > Messages > Blocked Contacts to see the full list. Tap "Edit" in the top right, then tap the minus sign next to a name and confirm to unblock them.
You can also unblock someone through Settings > Phone > Blocked Contacts or Settings > FaceTime > Blocked Contacts if you blocked them through those apps instead of Messages. Blocking in one app doesn't automatically block in the others — if you want to block someone from calling, texting, and FaceTiming, you may need to block them in multiple places.
When you unblock someone, they can text and call you again, and they'll see delivery confirmations on their messages. However, any messages they sent while blocked won't reappear in your inbox. If you want to see those old messages, you would need to restore your phone from a backup made before you blocked them.
What happens when you block someone
A blocked person can still call you — the call will ring on their end as normal, but you won't see it come through. They can still leave voicemails, which will appear in your voicemail inbox. They can also still send texts, but those messages won't show up in your Messages app at all.
The blocked person won't receive a notification that they're blocked. Their texts will appear to send normally on their end, and they won't see a "message not delivered" error. This means they may not realize they're blocked and could keep trying to reach you.
If you block someone and then they call you, the call goes straight to voicemail without ringing on your phone. If they text you, the message is silently discarded — they won't know it didn't go through. This can be useful if you want to avoid contact without confrontation, but it also means the person may not understand why you're not responding.
Blocking group texts and iMessage threads
Blocking someone removes them from group texts you're part of, but it doesn't remove you from group texts they create. If you're in a group message with someone you've blocked, their messages won't show up in that conversation, but you'll still see messages from everyone else.
If someone you've blocked creates a new group text and adds you to it, you'll see the conversation but not their individual messages within it. You can leave the group entirely by opening the conversation, tapping "Details" in the top right, scrolling down, and tapping "Leave this Conversation."
For iMessage threads specifically, blocking works the same way as regular texts. If you block someone in an iMessage conversation, that thread will no longer show their messages, but the conversation itself stays in your inbox. You can delete the conversation entirely if you want it out of your message list.
Blocking on iCloud and syncing across devices
If you have multiple Apple devices signed into the same iCloud account, blocking someone on one device syncs to the others. Block someone on your iPhone, and they'll be blocked on your iPad and Mac as well.
This sync happens automatically if you're signed into iCloud and have Messages syncing turned on. You can check this in Settings > [Your Name] > iCloud and make sure "Messages" is toggled on. If you turn off Messages syncing, blocks won't sync between devices, and you'd have to block someone separately on each phone or tablet.
If you use multiple phone numbers or email addresses in Messages, blocking applies to all of them. A person blocked on your main phone number is also blocked from reaching you through any email addresses you've set up for iMessage.
Frequently Asked Questions
Can someone tell if I've blocked them?
Not directly. Their calls will go to voicemail and their texts will appear to send normally, so they won't get an error message. However, if they notice you never respond and their calls always go straight to voicemail, they may suspect you've blocked them. There's no official way for them to confirm it.
What if I block someone by accident?
Go to Settings > Messages > Blocked Contacts, find the person's name, tap "Edit," and tap the minus sign to unblock them. They can text and call you again immediately. Any messages they sent while blocked still won't appear in your inbox.
Do blocked messages take up storage space on my iPhone?
No. Blocked messages are deleted from your device and don't count toward your storage. They're not stored anywhere on your phone, so blocking someone also frees up a tiny amount of space if they had sent you many messages.
Can I block someone from just texting but still allow calls?
No. Blocking on iPhone blocks both calls and texts together. If you want to allow calls but block texts, you would need to use a different approach, like using the "Do Not Disturb" feature and manually allowing specific contacts through, but that's not designed for this purpose and isn't a clean solution.
If I block someone, will they see my "typing" indicator or "read" receipts?
No. Once someone is blocked, they won't see any indicators that you've read their messages, that you're typing, or that you're online. They also won't see your location if you share it through Find My Friends, and any shared albums or notes will no longer be visible to them.
