You can block a number directly from your Phone app, Messages, or FaceTime

iPhone gives you several ways to block a number depending on where you see it. The fastest route is to open the Phone app, find the number in your recent calls or voicemail, swipe left on it, and tap Block this Caller. If the call came through Messages or FaceTime, you can block from there too — swipe left on the conversation and tap the block icon. Once blocked, that number cannot call, text, or FaceTime you, and their calls go straight to voicemail without your phone ringing.

You can also block a number before it ever calls you. Open Contacts, find the person or number you want to block, tap the info button (the circle with an "i"), scroll down, and select Block this Caller. This works whether the contact is saved in your phone or not — you can type in a number you want to block even if you have never spoken to that person.

Key Takeaways

  • Blocked numbers cannot call, text, or FaceTime you, and their calls go to voicemail without ringing your phone.
  • You can block a number from your recent calls, a text message, a FaceTime call, or your Contacts app.
  • Blocked callers can still leave voicemails, but you will not be notified and their messages go to a separate section.
  • You can unblock a number at any time by going to Settings > Phone > Blocked Contacts and swiping left on the name.
  • Blocking works only on your phone — the person can still reach you from a different number or contact you on other apps.

Where blocked calls and texts go

When you block a number, your phone stops showing you that person's calls and messages. Calls go straight to voicemail, and text messages disappear from your Messages app — you will not see a notification. The blocked person does not get a message saying they are blocked; their call or text straightforward goes through without a response from you.

Blocked voicemails do not disappear entirely. They go into a separate section in your Voicemail tab called Blocked Messages, which you can view if you want to. You will not get a notification when a blocked person leaves a voicemail, so you have to check that section manually if you are curious what they said.

How to see your full blocked list and unblock someone

Open Settings, tap Phone, then scroll down and tap Blocked Contacts. This shows every number you have blocked on your iPhone. If you want to unblock someone, swipe left on their name and tap Unblock. Once unblocked, that person can call and text you again, and you will see their calls and messages normally.

If you have blocked many numbers and want to find a specific one, you can scroll through the list or use the search function at the top. The list shows blocked contacts in the order you blocked them, with the most recent at the top.

Blocking does not stop calls from different numbers

A blocked number cannot reach you from that specific phone number, but the person can call from a different number and you will see it as a new call. If someone is harassing you from multiple numbers, you will need to block each one separately. There is no way to block an entire person across all possible numbers they might use.

If you are getting calls from many different numbers that seem to be the same person or organization, consider using Silence Unknown Callers instead. This feature, found in Settings > Phone, sends any call from a number not in your Contacts to voicemail automatically. It is broader than blocking individual numbers and works for any caller you do not know.

Blocking through iCloud and across your Apple devices

If you block a number on your iPhone, that block syncs to your other Apple devices through iCloud — iPad, Mac, and Apple Watch will all respect the block. This means a blocked number cannot reach you on any of those devices either. The sync happens automatically if you are signed into the same iCloud account on all your devices.

If you use multiple Apple devices but do not want the same blocks on all of them, make sure you are not signed into the same iCloud account, or turn off iCloud syncing for Contacts on the devices where you want different blocking rules.

What happens when you block someone on iMessage

If you block someone in the Messages app specifically, you are blocking them from texting you through iMessage (Apple's messaging service). However, if that person has your phone number and you have not blocked the number itself in your Phone settings, they can still reach you through regular SMS text messages. To fully block someone from texting you, block the number in your Phone app, not just in Messages.

Similarly, blocking someone in FaceTime only blocks them from calling you through FaceTime. They can still call your phone number or text you unless you block the number itself in your Phone app.

Frequently Asked Questions

Can a blocked person tell they are blocked?

No. When a blocked person calls, their call goes to voicemail without any indication that they are blocked. They do not receive a message saying the number is blocked. They may suspect it if calls consistently go to voicemail, but iPhone does not notify them.

Can I block a number that is not in my Contacts?

Yes. Open the Phone app, tap Keypad, enter the number, and tap the info button (circle with "i"). Scroll down and tap Block this Caller. You can block any number whether or not it is saved in your phone.

What if I block someone by accident?

Go to Settings > Phone > Blocked Contacts, find the name, swipe left, and tap Unblock. They can call and text you again when ready. There is no waiting period or confirmation needed.

Do blocked calls still use my data or minutes?

No. Blocked calls do not ring your phone or use your data. They go straight to voicemail without consuming any of your service.

Can I block a number from my voicemail?

Yes. In the Voicemail tab, tap the voicemail from the number you want to block, tap the info button, and select Block this Caller. This blocks the number and prevents future calls from reaching you.
