Blocking a contact 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. They won't see a notification that they've been blocked — the call or message straightforward fails on their end. You can block a contact in seconds from the Phone app, Messages app, or directly from a contact's card.

Blocking is different from muting notifications. If you mute someone, their calls and messages still come through, but your phone doesn't alert you. Blocking prevents the contact from reaching you at all. You can unblock someone at any time if you change your mind.

Key Takeaways

  • Blocked contacts cannot call, text, or FaceTime you, and their attempts fail silently without notifying them they're blocked.
  • You can block someone from the Phone app, Messages app, or by opening their contact card and scrolling to the block option.
  • Blocking does not delete the contact from your phone or remove past messages — you can unblock them later without losing anything.
  • If someone is blocked and tries to call, they hear a busy signal or the call goes to voicemail depending on their carrier.

Block someone from the Phone app

Open the Phone app and go to the Recents tab at the bottom. Find the person you want to block and swipe left on their name. A red circle with a phone icon and the word "Block" will appear on the right side. Tap "Block" and confirm by tapping "Block Contact" in the popup window.

If you want to block someone who isn't in your recent calls, tap the Contacts tab at the bottom of the Phone app instead. Find their name, tap it to open their card, scroll down, and tap "Block this Caller" in red text near the bottom.

Block someone from the Messages app

Open Messages and find the conversation with the person you want to block. Swipe left on their name or message thread. A red circle with a trash icon will appear, but keep swiping or tap the three dots that appear. You'll see a "Block" option — tap it and confirm.

Alternatively, open the conversation, tap their name at the top of the screen, and scroll down to find "Block this Caller" in red text. Tap it and confirm the action.

Block someone from their contact card

Open the Contacts app and find the person you want to block. Tap their name to open their full contact card. Scroll all the way to the bottom and tap "Block this Caller" in red text. A confirmation popup will appear — tap "Block Contact" to finish.

This method works the same way whether the person is saved in your contacts or not. If they're not saved, you can still open their card from a recent call or message and block them from there.

What happens after you block someone

Once blocked, that person cannot reach you through calls, text messages, or FaceTime. If they try to call, they'll hear a busy signal or the call will go to voicemail. If they text, the message won't be delivered. They won't receive a notification saying they've been blocked — their attempt straightforward fails.

The contact remains in your phone and all past messages stay in your conversation history. You can read old messages from them anytime. Blocking only stops new contact attempts going forward.

Unblock someone if you change your mind

Open Settings and scroll down to find "Phone" or "Messages" depending on where you blocked them. Tap it, then look for "Blocked Contacts" or "Blocked Messages & Calls." You'll see a list of everyone you've blocked. Find the person you want to unblock, swipe left on their name, and tap "Unblock."

After you unblock someone, they can call, text, and FaceTime you again when ready. You don't lose any old messages or contact information — everything returns to normal.

Block unknown callers and spam

If you're getting calls from numbers not in your contacts, you can silence them without blocking each one individually. Open Settings, tap "Phone," then turn on "Silence Unknown Callers." Unknown numbers will go straight to voicemail, but calls from people in your contacts will ring normally.

For text spam, open Settings, tap "Messages," and turn on "Filter Unknown Senders." Texts from unknown numbers go to a separate tab so they don't clutter your main conversation list. This is useful if you're getting repeated spam without wanting to block individual numbers.

Frequently Asked Questions

Can someone tell if I've blocked them?

Not directly. When they call, they hear a busy signal or the call goes to voicemail. When they text, the message fails to send. They might suspect they're blocked if calls always go to voicemail and texts never deliver, but iPhone doesn't send them a notification saying you blocked them.

Do blocked contacts see my old messages?

No. Once you block someone, they cannot see any of your messages, including ones you sent before blocking them. The conversation disappears from their view. If you unblock them later, they still cannot see those old messages.

What if I block someone by accident?

Go to Settings, find "Phone" or "Messages," tap "Blocked Contacts," find the person's name, swipe left, and tap "Unblock." They can reach you again when ready. Your old messages with them will reappear in your conversation list.

Can I block someone from FaceTime only?

No. Blocking on iPhone blocks calls, texts, and FaceTime all together. You cannot block someone from just one service. If you want to stop FaceTime calls but allow texts, you would need to turn off FaceTime in Settings instead, though that affects all incoming FaceTime requests.

Will blocking someone delete our conversation?

No. Your message history with them stays in your Messages app. You can still read old conversations. Blocking only stops new messages from coming in — it doesn't erase what you've already exchanged.
