Block a specific contact's messages in Settings

The fastest way to stop texts from one person is through your iPhone's built-in blocking feature. Open Settings, then tap Messages. Scroll down and tap Blocked Contacts. Tap Add New and select the contact you want to block from your list. That person can still call you, but their text messages will not arrive on your phone.

If you do not have the contact saved in your phone yet, you can block by phone number instead. In the same Blocked Contacts screen, tap Add New and type the number manually. The block works the same way — messages from that number simply will not come through.

Block someone directly from a conversation

You do not have to go into Settings. Open the Messages app, find the conversation with the person you want to block, and swipe left on their name. A red Block button appears. Tap it, then confirm. The conversation stays in your message list, but no new messages from that person will reach you.

This method is useful when you are already looking at a message thread and want to stop it immediately. The block takes effect right away — if they text you again in the next few seconds, you will not see it.

Key Takeaways

  • Blocked contacts cannot send you text messages, but they can still call you unless you block them separately in the Phone app.
  • You can block by contact name through Settings > Messages > Blocked Contacts, or by swiping left on a conversation in the Messages app.
  • Blocked people do not receive a notification that you blocked them, but they may notice their messages are not being delivered.
  • You can unblock someone at any time by going to Settings > Messages > Blocked Contacts, swiping left on their name, and tapping Unblock.

What happens when you block someone

When you block a contact, their text messages do not arrive on your phone at all. They will not see a "delivered" or "read" status on their end — the message simply fails to send. From their perspective, it looks like the message went through, but they will not get a response and will not see a delivery confirmation.

The blocked person can still leave you voicemails and call you, though the call will ring normally on their end while you see nothing. If you want to block calls as well, you need to block them separately in the Phone app. Messages and Phone have separate block lists.

Unblock a contact if you change your mind

Open Settings, tap Messages, then Blocked Contacts. Find the person you want to unblock, swipe left on their name, and tap Unblock. Their messages will start coming through again immediately.

Unblocking does not restore old messages that arrived while they were blocked — those are gone. But any new messages from that person will appear in your inbox normally. You can block and unblock the same person as many times as you need to.

Block unknown senders and filter unknown numbers

If you are getting texts from numbers not in your contacts, you can turn on Filter Unknown Senders. Go to Settings > Messages and toggle on Filter Unknown Senders. Messages from people not in your contacts will go into a separate tab called Unknown Senders instead of your main inbox.

This does not block the messages — they still arrive on your phone — but they stay out of your way. You can check that tab whenever you want to see if anything important came through. This is useful if you get a lot of spam or marketing texts but do not want to block specific numbers one at a time.

Report spam and block at the same time

If a message is clearly spam or harassment, you can report it while blocking. Open the conversation, tap the contact name at the top, scroll down, and tap Block this Caller. A menu appears asking if you want to report the message as spam. Tap Report Spam if you do, then confirm the block. Your report helps Apple identify patterns of spam across all iPhones.

Reporting does not do anything to the sender — they are not notified or punished. But it helps train Apple's systems to catch similar messages before they reach other people. You can report and block in one action, or just block without reporting if you prefer.

Frequently Asked Questions

Can a blocked contact see that I blocked them?

No notification is sent to them, but they may figure it out if their messages stop delivering and you stop responding. There is no way for them to know for certain through the Messages app itself.

Do blocked messages take up storage space on my iPhone?

No. Blocked messages never arrive on your phone, so they do not use any storage. If you delete a conversation before blocking someone, those old messages are already gone.

If I block someone in Messages, are they blocked in FaceTime too?

No. Messages and FaceTime have separate block lists. You need to block them in FaceTime separately if you want to prevent FaceTime calls. Go to Settings > FaceTime > Blocked Contacts to do that.

What is the difference between blocking and muting a conversation?

Muting silences notifications from a conversation but messages still arrive and you can read them. Blocking prevents messages from arriving at all. Use muting for people you want to hear from later but not right now.

Can I block a number that is not saved as a contact?

Yes. Go to Settings > Messages > Blocked Contacts, tap Add New, and type the phone number. You do not need to save it as a contact first.
