Blocking a contact on iPhone stops them from calling, texting, or FaceTiming you

When you block someone on iPhone, their calls go straight to voicemail, their text messages don't arrive, and FaceTime requests are rejected. The blocked person won't get a notification that they're blocked — their message will simply fail to send, or the call will ring once before going to voicemail. You can block a contact in seconds from your Phone, Messages, or FaceTime app, and you can unblock them just as quickly if you change your mind.

Blocking is different from muting notifications. A muted contact can still reach you; you just won't hear or see their messages until you check. Blocking prevents contact entirely.

Key Takeaways

  • You can block a contact directly from the Phone, Messages, or FaceTime app by finding their name and selecting the block option.
  • A blocked person's calls go to voicemail and their texts don't arrive, but they won't receive a notification that they're blocked.
  • Blocking someone on iPhone does not delete their contact information or your conversation history with them.
  • You can see a list of all blocked contacts in Settings under Phone, Messages, or FaceTime, and unblock anyone from that same list.

Block someone from the Phone app

Open the Phone app and find the contact you want to block. This can be someone in your Recents list or in your Contacts. Tap the information icon (the small "i" in a circle) next to their name.

Scroll to the bottom of their contact card and tap Block this Caller. A confirmation message will appear asking if you're sure — tap Block Contact to confirm. The person is now blocked.

Block someone from the Messages app

Open Messages 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 from the options that show up.

Alternatively, swipe left on the conversation thread (on iPhone with Face ID) or tap Edit in the upper left, then tap the minus sign next to the conversation. A Block option will appear — tap it to confirm.

Block someone from the FaceTime app

Open FaceTime and find the person you want to block in your Recents list or Contacts. Tap the information icon next to their name. Scroll down and tap Block this Caller, then confirm by tapping Block Contact.

If you want to block someone who called you on FaceTime, you can also tap the information icon next to their name in your Recents list and follow the same steps.

View and manage your blocked contacts list

To see everyone you've blocked, open Settings and go to Phone, Messages, or FaceTime depending on which app you want to check. Scroll down and tap Blocked Contacts. You'll see a list of everyone you've blocked in that app.

To unblock someone, tap Edit in the upper right corner, then tap the red minus sign next to their name. Tap Unblock to confirm. They can now call, text, or FaceTime you again.

What happens when you block someone

When you block a contact, they cannot call you, send you text messages, or reach you on FaceTime. Their calls will ring once and then go to voicemail. Text messages they send will fail to deliver, and they'll see a message saying the text couldn't be sent. FaceTime requests will be rejected without ringing on your end.

The blocked person will not see a notification saying they're blocked. From their perspective, it will simply appear that you're not answering or that messages aren't going through. Your contact information remains in their phone, and they can still see your profile picture and status if you haven't changed your privacy settings.

Blocking someone does not delete your conversation history with them. If you unblock them later, all previous messages and call logs will still be there.

Block someone you don't have as a contact

If someone has called or texted you and you don't have them saved as a contact, you can still block them. In the Phone app, find their number in your Recents list and tap the information icon. Tap Block this Caller. In Messages, find their number or name in your conversation list, press and hold, and tap Block.

You don't need to save their number first — the block will work on their phone number or Apple ID regardless of whether they're in your contacts.

Frequently Asked Questions

Will the person know I blocked them?

No. They won't receive a notification. Their calls will go to voicemail and texts will fail to send, but they won't see a message saying you blocked them. Over time, they may figure it out if calls consistently go to voicemail, but iPhone doesn't tell them directly.

Can I block someone and still see their old messages?

Yes. Blocking someone does not delete your conversation history. You can still read old messages from them, but new messages they send won't arrive. If you unblock them later, new messages will start coming through again.

What if I block someone by accident?

Go to Settings, then Phone, Messages, or FaceTime. Tap Blocked Contacts, tap Edit, and tap the red minus sign next to their name. Tap Unblock to confirm. They can contact you again immediately.

Can I block someone on just one app, like Messages, but not Phone?

Yes. Blocking in Messages only blocks them in that app. They can still call you on the Phone app or reach you on FaceTime. You have to block them separately in each app if you want to block them everywhere.

Does blocking someone delete their contact from my phone?

No. Their contact information stays in your Contacts app. Blocking only prevents them from reaching you — it doesn't remove their name, number, or email address from your phone.
