The fastest way to block a caller

Open the Phone app, find the number or contact you want to block, tap the info button (the circle with an "i"), scroll down, and tap Block this Caller. That number can no longer call or text you — the calls go straight to voicemail and texts disappear without a notification. You can also block someone directly from a recent call by swiping left on their name and tapping the block icon.

If someone texts you first, open Messages, press and hold their name or number, tap Block, then confirm. The same action works in FaceTime — tap the info button on a recent call and select Block this Caller.

Blocked contacts don't know they're blocked. Their calls ring on their end as normal, but you never hear them. Texts they send sit in their phone as "delivered" even though you never receive them.

Key Takeaways

  • You can block a number from the Phone app, Messages, or FaceTime by finding the contact and selecting the block option from their info screen.
  • Blocked callers hear a normal ring but their calls go to your voicemail, and their texts never reach you.
  • You can unblock anyone anytime by going to Settings > Phone > Blocked Contacts (or Settings > Messages > Blocked Contacts for text-only blocks).
  • Blocking someone in one app (like Messages) does not automatically block them in Phone or FaceTime — you may need to block them separately in each app.
  • Do Not Disturb and Focus modes let you silence calls from everyone except your contacts, which is different from blocking and still lets them reach your voicemail.

Blocking from your blocked contacts list

You can also block numbers without having them in your recent calls or messages. Go to Settings > Phone > Blocked Contacts and tap the plus sign in the top left. Search for the contact or type the number you want to block, then tap Block.

This method is useful when you want to block a number you've never called or that hasn't contacted you yet. You can add as many numbers as you need, and there's no limit to how many people you can block on an iPhone.

Blocking across different apps

Blocking works differently depending on which app the contact uses to reach you. If someone calls you through the Phone app, blocking them there stops phone calls but may not stop FaceTime calls or iMessages from the same person. You need to block them separately in each app if you want to block all forms of contact.

To block in FaceTime, open the app, find the recent call, tap the info button, and select Block this Caller. To block in Messages, press and hold the conversation and tap Block. Someone blocked in Messages can still call you on the Phone app unless you block them there too.

If you want to block someone across all Apple services at once, the most reliable way is to block them in Settings > Phone > Blocked Contacts, then repeat the process in Messages and FaceTime.

Unblocking a number

To unblock someone, go to Settings > Phone > Blocked Contacts and swipe left on their name or number. Tap Unblock. You can also tap Edit in the top left, then tap the minus sign next to a contact and confirm.

If you blocked them in Messages or FaceTime instead, go to Settings > Messages > Blocked Contacts or Settings > FaceTime > Blocked Contacts and unblock them the same way. Once unblocked, they can call, text, or FaceTime you normally again.

Using Do Not Disturb or Focus modes instead

Do Not Disturb and Focus modes silence calls and notifications from everyone except your contacts, favorites, or people you choose. This is different from blocking — the person can still reach you, but you won't hear them unless they call twice in three minutes (a built-in emergency override). Go to Settings > Focus to set one up, or swipe up from the bottom of your screen and tap the Focus icon to turn one on quickly.

Use Do Not Disturb or a Focus mode when you want temporary silence without permanently blocking someone. Use blocking when you want to stop contact from someone permanently. You can have both active at the same time — a blocked contact still can't reach you even if Do Not Disturb is off.

What happens to blocked calls and texts

When someone you've blocked calls you, the call goes straight to your voicemail. They hear a normal ring and may leave a message, but you won't see a missed call notification. Their voicemail sits in your voicemail inbox like any other, but you'll know it's from a blocked number because the caller ID will show their name or number.

Texts from blocked contacts never arrive on your phone. They don't appear in your Messages app, and you get no notification. The person sending the text sees it as "delivered," so they may not realize you've blocked them. If they call you instead, they'll hear a normal ring, which can create confusion about why their texts aren't getting through.

Blocking spam and unknown numbers

If you're getting calls from numbers you don't recognize, you can block them one at a time using the methods above. For broader protection, go to Settings > Phone > Silence Unknown Callers and turn it on. This sends all calls from numbers not in your contacts to voicemail automatically, though you'll still see them in your recent calls list.

Some carriers also offer spam-filtering tools through their own apps or settings. Check with your carrier (AT&T, Verizon, T-Mobile, etc.) to see if they provide additional spam-blocking options. Third-party apps like Nomorobo or Truecaller can also filter spam calls, though they require separate setup and permissions.

Frequently Asked Questions

Can someone tell if I've blocked them?

No direct notification tells them, but they may figure it out. Their calls go to voicemail every time, and if they text you, the messages show as "delivered" but you never respond. If they try FaceTime, it may behave differently than a normal decline. There's no way for them to know for certain without asking you directly.

What if I block someone by accident?

Go to Settings > Phone > Blocked Contacts, find their name, swipe left, and tap Unblock. If you blocked them in Messages or FaceTime, unblock them in those apps' settings instead. Once unblocked, they can reach you normally again.

Do blocked contacts still see my location or status?

Blocking only stops calls, texts, and FaceTime. It does not hide your location from Find My Friends or change your status in other apps. If you want to hide your location from someone, you need to remove them from Find My or adjust those settings separately.

Can I block a number that's not saved as a contact?

Yes. Go to Settings > Phone > Blocked Contacts, tap the plus sign, and type or paste the number. You don't need their name or contact information — just the phone number is enough to block them.

If I block someone in iCloud, does it block them on all my devices?

Blocking syncs across your iPhone, iPad, and Mac if you're signed into the same iCloud account. If you block someone on your iPhone, they're automatically blocked on your other Apple devices too. The same applies if you unblock them.
