Where to find the block feature on your iPhone

The block feature on iPhone lives in the Phone app, not in Settings. Open Phone, tap Recents (the clock icon at the bottom), find the number or contact you want to block, swipe left on it, and tap the red block icon. You can also tap the information icon next to any recent call, scroll to the bottom, and select Block This Caller.

If you want to block someone before they call you, open Contacts, find their name, tap the information icon, scroll down, and select Block This Caller. The same option appears in Messages if you want to block a contact from texting you.

Once you block a number, that person cannot call you, text you, or reach you through FaceTime. Their calls go straight to voicemail, and you will not see a notification that they tried. They will not know they are blocked — they will just hear the phone ring and then get your voicemail.

Key Takeaways

  • You can block a caller directly from your recent calls list by swiping left and tapping the block icon.
  • Blocked callers can still leave voicemails, but you will not receive a notification that they called.
  • Blocking works across Phone, Messages, and FaceTime at the same time.
  • You can unblock someone at any time by going to Settings > Phone > Blocked Contacts and swiping left to remove them.
  • Blocked contacts cannot see that they are blocked — their calls straightforward ring through to voicemail.

How to see your full list of blocked numbers

Your blocked contacts list is in Settings, not in the Phone app. Open Settings, tap Phone, and scroll down to Blocked Contacts. This shows every number and contact you have blocked on your device.

From this list, you can swipe left on any blocked contact to unblock them. Once you unblock someone, they can call and text you normally again. There is no confirmation step — swiping left and tapping Unblock removes them when ready.

Blocking unknown or spam callers

If you get a call from an unknown number, you can block it the same way you block a known contact. Swipe left on the number in Recents and tap block. You do not need to know who the person is.

iPhone also has a feature called Silence Unknown Callers that sends calls from numbers not in your contacts straight to voicemail without ringing your phone. This is different from blocking — the calls still come through, you just do not hear them. To turn this on, go to Settings > Phone > Silence Unknown Callers and toggle it on.

If you are getting repeated spam calls, blocking individual numbers works, but Silence Unknown Callers is usually faster because it handles all unknown numbers at once. You can use both at the same time.

What happens when you block someone on iMessage or FaceTime

Blocking a contact in Messages or FaceTime does not automatically block their phone calls. If you want to block someone completely — calls, texts, and FaceTime — you need to block them from the Phone app or Contacts app, which blocks them across all three services at once.

If you block someone only in Messages, they can still call you and reach you on FaceTime. If you block them only in FaceTime, they can still text and call. To be thorough, use the Phone app or Contacts method, which blocks them everywhere.

Blocking contacts on a shared family device

If you share an iPhone with family members, blocking a contact blocks them for everyone on that device. There is no way to block a number for just one person on a shared phone. If you need separate block lists, each person needs their own Apple ID and their own device, or you need to use Screen Time parental controls to manage what different family members can access.

If you are the account holder and want to block numbers for a child's device, you can do that through Family Sharing in Settings. Open Settings, tap your name, tap Family Sharing, select the child's account, and manage their blocked contacts from there.

Unblocking a contact and what to expect

To unblock someone, go to Settings > Phone > Blocked Contacts, find their name, swipe left, and tap Unblock. Once you unblock them, they can call and text you when ready. You will see their calls in your recent list and their messages in your conversation threads.

Unblocking does not restore old messages or calls from when they were blocked — those are gone. It only opens the line of communication going forward. If you unblock someone by mistake, you can block them again the same way.

Why a blocked caller can still leave voicemail

When you block someone, their calls go to voicemail, but they can still leave a message. That voicemail goes into a separate folder called Blocked Messages in your voicemail app. You can listen to it if you want, but you will not get a notification.

If you do not want blocked callers to leave voicemail at all, you would need to set up a custom voicemail greeting that hangs up before the beep, but most people leave this as is. The blocked messages folder keeps them separate from your regular voicemail, so they do not clutter your main inbox.

Frequently Asked Questions

Can someone tell if I blocked them?

No. When you block someone, their calls ring through to voicemail just like a normal unanswered call. They will not see a message saying they are blocked, and they will not get an error. They may suspect it if you never respond, but the phone will not tell them.

What if I block someone and then they text me from a different number?

Blocking only works on the specific number you blocked. If the person texts or calls from a different phone number, you will see it and hear it normally. You would need to block that new number separately.

Do blocked contacts see my voicemail greeting?

Yes. When a blocked caller reaches your voicemail, they hear your regular greeting and can leave a message. The only difference is that you will not be notified, and the message goes to your Blocked Messages folder instead of your main inbox.

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

Yes. You can block any phone number, whether it is saved in your contacts or not. Find it in your recent calls list, swipe left, and tap block. You do not need to know who the person is.

If I block someone, will they know when I unblock them?

No. Unblocking is invisible to the other person. They will not get a notification. If you unblock them and they call or text, they will just see that the call or message goes through normally.
