The fastest way to block a contact

Open the Phone app, find the contact you want to block, tap the information icon (the small "i" in a circle), scroll down, and tap Block this Caller. That person can no longer call, text, or FaceTime you, and their messages will not show up in your inbox. If you change your mind later, you can unblock them the same way.

You can also block someone directly from a text conversation. Open Messages, find the thread, swipe left on the contact's name at the top, and tap Block. Or block them from a FaceTime call by tapping the information icon during or after the call and selecting Block this Caller.

Blocking works across all communication methods on your iPhone at once — calls, texts, FaceTime, and iMessage all stop coming through. The blocked person will not receive a notification that you blocked them, but they may figure it out if their calls go straight to voicemail or their texts show as delivered but you never respond.

Key Takeaways

  • You can block someone from the Phone app, Messages app, or FaceTime by finding their contact and selecting the block option from their information screen.
  • A blocked person cannot reach you by call, text, iMessage, or FaceTime, and their messages will not appear in your inbox.
  • The blocked person does not receive a notification that you blocked them, though they may notice their calls go to voicemail.
  • You can unblock someone at any time by going to their contact information and tapping Unblock this Caller.

Blocking from the Contacts app

If you prefer to manage blocks from your Contacts app, open it and find the person you want to block. Tap their name to open their contact card, then tap the information icon (the small "i" in a circle) at the top right. Scroll down and tap Block this Caller. This method works the same way as blocking from Phone or Messages — the person is blocked across all communication types.

This approach is useful if you have someone in your contacts but have never called or texted them recently. You do not have to dig through your call history or message threads to find them.

What happens when you block someone

When you block a contact, their calls go straight to voicemail without ringing your phone. Text messages from them will not appear in your Messages app at all — they simply disappear. If they try to FaceTime you, the call will not come through. From their perspective, they will see their call go to voicemail, their texts will show as delivered (not read), and their FaceTime calls will appear to ring but you will not answer.

The blocked person remains in your contacts list, but you will not see any new messages or calls from them. If they contact you from a different phone number, that call or message will come through normally because the block is tied to their specific contact, not their identity.

Blocking is permanent until you unblock them. There is no time limit — a blocked contact stays blocked until you manually remove the block.

Unblocking someone later

To unblock someone, open the Phone app and tap Contacts at the bottom. Find the person you want to unblock, tap their name, then tap the information icon. Scroll down and tap Unblock this Caller. You can also unblock from the Contacts app or Messages app using the same steps.

Once you unblock someone, they can call, text, and FaceTime you again. Any messages they sent while blocked will not reappear — those are gone. Going forward, you will see their new messages and calls normally.

Blocking unknown or spam callers

If you receive a call from an unknown number and want to block it, you do not need to add them to your contacts first. During the call, tap the information icon and select Block this Caller. You can also block an unknown number from your recent calls list by swiping left on the number and tapping Block.

For text messages from unknown numbers, open the message thread, swipe left on the contact name at the top, and tap Block. Unknown numbers you block will not be able to reach you going forward, even if they use different numbers.

Blocking in iCloud and across devices

If you use iCloud and have multiple Apple devices, your block list syncs across them. When you block someone on your iPhone, they are also blocked on your iPad and Mac if those devices are signed into the same iCloud account. This means you do not have to block the same person separately on each device.

If you sign out of iCloud on one device, the block list on that device will no longer sync with your other devices. The blocks you made on that device stay in place, but new blocks you make elsewhere will not appear there.

Frequently Asked Questions

Can a blocked person tell that I blocked them?

They will not receive a notification, but they may figure it out. Their calls will go straight to voicemail, their texts will show as delivered but you will not respond, and FaceTime calls will not connect. Some people realize they have been blocked when this pattern continues.

What if someone blocks me on their iPhone?

Your calls will go to voicemail, your texts will show as delivered, and FaceTime calls will not ring through. You will not receive a notification that you have been blocked. The only way to know for certain is to ask them directly or notice the pattern of unanswered calls and messages.

Can I block someone without them being in my contacts?

Yes. You can block an unknown number directly from your recent calls list or from a text message thread without adding them to your contacts. Swipe left on the number or message and tap Block.

If I block someone, do old messages disappear?

No. Messages you received before blocking them stay in your Messages app. Only new messages from that person will not appear. If you want to delete the old conversation, you can swipe left on the thread and tap Delete.

Can I block someone from FaceTime only, not from calls and texts?

No. Blocking on an iPhone blocks someone across all communication methods at once — calls, texts, iMessage, and FaceTime. You cannot block them from just one type of communication.
