You can see your blocked numbers list in Settings, and unblock any number whenever you want

Your iPhone keeps a record of every number you've blocked, and you can view that list anytime in the Settings app. Open Settings, go to Phone, then tap Blocked Contacts. You'll see the phone numbers and contacts you've blocked. From there, you can unblock any number by swiping left on it and tapping Unblock, or by tapping Edit and then the red minus sign next to the contact.

Blocked numbers can't call or text you, and their calls go straight to voicemail without your phone ringing. Messages from blocked numbers don't appear in your Messages app at all. If you change your mind about blocking someone, unblocking them takes seconds and restores normal communication.

Key Takeaways

  • Your blocked numbers list is in Settings > Phone > Blocked Contacts, and you can view it anytime.
  • Unblock a number by swiping left on it in the Blocked Contacts list and tapping Unblock.
  • Blocked callers can still leave voicemails, but you won't see a notification and their messages won't show in your voicemail list by default.
  • You can block a number directly from a call, text, or contact card without opening Settings.

How to find your blocked numbers in Settings

Open the Settings app on your home screen. Scroll down and tap Phone. In the Phone settings menu, look for Blocked Contacts near the bottom and tap it. This screen shows every number you've blocked on your device.

The list displays the phone number or contact name if you had the number saved in your contacts before blocking it. If you blocked an unknown number, you'll see just the digits. Tapping on any entry shows you when you blocked it (though the exact date isn't always displayed) and gives you the option to unblock immediately.

Unblocking a number you've blocked

To unblock a single number, open Settings > Phone > Blocked Contacts. Find the number you want to unblock, swipe left on it from right to left, and tap the red Unblock button that appears. The number is now unblocked and can reach you again.

Alternatively, tap Edit in the top left corner of the Blocked Contacts screen. Red minus signs appear next to each number. Tap the minus sign next to the number you want to unblock, then tap Delete. Both methods do the same thing — they remove the block and restore normal communication with that contact.

Blocking a number directly from calls or messages

You don't have to go into Settings to block someone. When you receive a call from a number you want to block, tap the info button (a small circle with an "i" inside) on the call screen, scroll down, and tap Block this Caller. The call ends and the number is added to your blocked list.

In the Messages app, open a conversation from someone you want to block, tap their name at the top, scroll down, and tap Block this Caller. In your Contacts app, open a contact, tap Edit, scroll to the bottom, and tap Block this Contact. All three methods add the number to your Blocked Contacts list instantly.

What happens when you block a number

When you block a number, the person calling or texting you won't know they're blocked — there's no notification sent to them. Their calls go straight to voicemail, but they won't hear a busy signal or any message saying they're blocked. Text messages from blocked numbers don't appear in your Messages app at all.

Blocked callers can still leave voicemails, but those voicemails appear in a separate section at the bottom of your Voicemail tab, not mixed in with your regular messages. You can listen to them if you want, or delete them without listening. This setup lets you block someone without them realizing it, but also gives you a way to hear what they said if it's important.

Blocking contacts across your Apple devices

If you block a number on your iPhone, that block syncs to your iPad and Mac through iCloud, as long as you're signed into the same Apple ID on all devices. This means if you block someone on your iPhone, they're automatically blocked on your iPad too. The sync works both ways — blocking on any device updates your blocked list everywhere.

This automatic syncing applies only to phone numbers and contacts. If you use FaceTime on your Mac or iPad, you may need to block the person separately in FaceTime settings, since FaceTime has its own block list. Check FaceTime settings on each device if you want to block someone from video calls as well as phone calls.

Recovering access if you blocked someone by accident

If you blocked a number by mistake, the process to fix it is the same as unblocking any other number. Go to Settings > Phone > Blocked Contacts, find the number, and swipe left to tap Unblock. There's no waiting period or confirmation step — unblocking happens immediately.

If you can't remember which number you blocked, look through your Blocked Contacts list. If the number isn't saved in your contacts, you'll see just the phone number digits. If you're not sure whether a specific person is blocked, you can try calling them from another phone, or ask them if they've been able to reach you recently. Once you unblock them, they can call and text you normally again.

Frequently Asked Questions

Can a blocked number still leave me a voicemail?

Yes. Blocked numbers can still leave voicemails, but they appear in a separate Blocked section at the bottom of your Voicemail tab. You won't get a notification when they leave a message, and you have to scroll down to see it.

Will someone know if I block them?

No. They won't receive any notification that you've blocked them. Their calls go to voicemail and their texts disappear, but they have no way to know for certain that you blocked them rather than simply not answering.

Do I need to unblock someone before they can text me again?

Yes. Until you unblock a number, they can't reach you by call or text. Unblocking restores full communication immediately.

What's the difference between blocking a contact and blocking a number?

On iPhone, blocking a contact and blocking a number are the same thing. If a contact has multiple phone numbers, blocking the contact blocks all of them. If you block just one number from a contact, only that number is blocked.

If I delete a contact, does that unblock them?

No. Deleting a contact doesn't unblock them. You have to go to Settings > Phone > Blocked Contacts and unblock them separately. The block remains even if you remove them from your contacts.
