Why a blocked number might still reach you

A blocked number on your iPhone cannot call you directly — but it can still leave voicemails, send text messages, and reach you through apps like FaceTime or iMessage. If you blocked someone's phone number through the Phone app, they cannot use that same number to call you. However, they can switch to a different number, use a spoofing service to mask their real number, or contact you through messaging apps you haven't blocked them on.

The confusion often comes from the difference between blocking a contact and blocking a number. When you block a contact in your Contacts app, you block all the phone numbers and email addresses associated with that contact. When you block a specific number in the Phone app, you block only that one number. If the person has multiple numbers, you need to block each one separately.

Key Takeaways

  • Blocked numbers cannot call you, but they can still send iMessages, FaceTime requests, and voicemails unless you block them in those apps too.
  • Blocking a contact in your Contacts app blocks all their numbers at once, while blocking through the Phone app blocks only that specific number.
  • You can block numbers in the Phone app, Messages app, FaceTime app, and Mail app — each app maintains its own block list.
  • If someone is reaching you from a different number, you need to block that new number separately in the same app where they contacted you.
  • Blocked contacts cannot see that they are blocked; calls go straight to voicemail and messages appear to send normally on their end.

Block a number directly from the Phone app

Open the Phone app and go to the Recents tab at the bottom. Find the number you want to block, swipe left on it, and tap the trash icon to delete it from recents first (optional but keeps your list clean). Then tap the information icon (the small circle with an "i") next to the number. Scroll down and tap Block this Caller. Confirm by tapping Block Contact.

If you want to block a number that is already in your Contacts app, open Contacts, find the person, tap Edit in the top right, scroll to the bottom, and tap Block this Contact. This blocks all phone numbers and email addresses linked to that contact at once, which is faster than blocking each number individually.

Block numbers in Messages and FaceTime separately

Blocking a phone number in the Phone app does not automatically block that person from sending you text messages or FaceTime requests. You need to block them in each app where they can reach you. Open the Messages app, find the conversation with the number you want to block, swipe left on it, tap More (the three dots), and select Block this Caller.

For FaceTime, open the FaceTime app, find the person in your recents or contacts, swipe left on their name, tap the information icon, and select Block this Caller. If someone is using a different number or email address to contact you through FaceTime, you need to block that specific contact method in FaceTime — blocking their phone number in the Phone app will not stop a FaceTime call from their email address.

Block numbers that are spoofed or coming from different numbers

If you keep getting calls from numbers that look similar to yours or from numbers you do not recognize, the caller may be using a spoofing service to hide their real number. Each spoofed number needs to be blocked individually because they are technically different numbers. Block each one in the Phone app using the steps above.

If you suspect the calls are coming from the same person using different numbers, block them in your Contacts app instead. This blocks all current and future contact information linked to that contact. However, if they add a completely new phone number to their account, you will need to block that new number separately once it reaches you.

Check your block list and unblock if needed

To see all the numbers you have blocked in the Phone app, open Settings, scroll down and tap Phone, then tap Blocked Contacts. This shows every number you have blocked through the Phone app. To unblock a number, swipe left on it and tap Unblock.

Your Messages app, FaceTime app, and Mail app each keep their own separate block lists. To see blocked contacts in Messages, open the app, tap Edit in the top left, then tap Show Blocked (if you do not see this option, you have no blocked contacts in Messages). In FaceTime, go to Settings > FaceTime > Blocked Contacts. In Mail, go to Settings > Mail > Blocked Contacts. You can unblock from any of these lists the same way — swipe left and tap Unblock.

What blocked callers experience on their end

When you block someone, they do not receive a notification that they have been blocked. Their call goes straight to your voicemail, and to them it sounds like a normal unanswered call. Text messages they send appear to deliver normally on their phone, but you never receive them. FaceTime requests show as unanswered calls on their end.

Because blocked callers do not know they are blocked, they may keep trying to reach you from the same number or try a different number. If someone is persistently contacting you from multiple numbers, blocking each one individually becomes tedious — in that case, consider using Do Not Disturb or Focus modes to silence calls and messages from unknown numbers while you decide your next step.

Use Do Not Disturb and Focus modes as an alternative

If you are being contacted by many unknown numbers or spoofed numbers, blocking each one individually is not practical. Instead, open Settings, tap Focus, and create a new Focus mode (or use the built-in Do Not Disturb mode). Set it to allow calls only from your Contacts, Favorites, or a specific group. This silences all other calls and notifications while still letting important people reach you.

You can schedule a Focus mode to turn on automatically at certain times or locations. For example, you could set Do Not Disturb to set up every evening and only allow calls from people in your Favorites list. This stops unwanted calls without having to block each number individually, and you can turn it off whenever you need to receive calls from unknown numbers.

Frequently Asked Questions

Can a blocked number still send me voicemails?

Yes. When you block a number in the Phone app, their calls go straight to voicemail, but they can still leave messages. You will see their voicemail in your voicemail list, but it will not trigger a notification. If you do not want to hear from them at all, you can delete their voicemails without listening to them.

If I block someone in Messages, are they also blocked in the Phone app?

No. Each app maintains its own block list. Blocking a number in Messages only blocks them from texting you — they can still call you through the Phone app. You need to block them separately in each app where you want to prevent contact.

What happens if a blocked contact calls me from a different number?

The call will go through because you have only blocked their original number. You will need to block the new number in the Phone app. If the same person keeps contacting you from different numbers, blocking them in your Contacts app (instead of blocking individual numbers) will block all their contact information at once, though new numbers they add later will still need to be blocked separately.

Can I block an unknown number before they call me?

No, you can only block a number after it has contacted you. However, you can use Focus modes to silence calls from unknown numbers automatically. Go to Settings > Focus > Do Not Disturb and set it to allow calls only from your Contacts. This prevents unknown numbers from reaching you without having to block them individually.

Will a blocked contact know I blocked them?

No. They will not receive any notification. Their calls go to voicemail and their messages appear to send normally on their end, so they have no way to know they are blocked unless they try contacting you and notice a pattern of unanswered calls and messages.
