The fastest way to block someone on iPhone

Open the Phone app, Messages app, or FaceTime app — whichever one the person contacted you through. Find their name or number in your recent calls, messages, or FaceTime history. Tap the "i" icon (information circle) next to their name, scroll down, and tap "Block this Caller" or "Block Contact". Confirm when prompted. That person can no longer call, text, or FaceTime you, and their messages will not appear in your inbox.

If you want to block someone who is not in your recent history, open Contacts, find their name, tap the "i" icon, scroll to the bottom, and select "Block this Contact". The steps are the same whether you are blocking a phone number, email address, or contact name.

Once blocked, the person will not receive a notification that you blocked them. Their calls go to voicemail as if your phone is off, and their text messages appear to send successfully on their end but never reach you. You can unblock them at any time by going back to that contact and tapping "Unblock this Contact".

Key Takeaways

  • You can block someone directly from the Phone, Messages, or FaceTime app by tapping the information icon next to their name and selecting the block option.
  • Blocked people cannot reach you by call, text, or FaceTime, and their messages will not appear in your inbox.
  • The person you block will not receive a notification that you blocked them.
  • You can unblock someone at any time through their contact card or by removing them from your blocked list in Settings.

Blocking from the Contacts app

If you have the person saved as a contact, the Contacts app is often the clearest place to block them. Open Contacts, search for or scroll to the person's name, and tap it to open their full contact card. Tap the "i" icon in the top right corner, then scroll down past their phone number and email address until you see "Block this Contact" in red text. Tap it and confirm.

This method works whether the contact has one phone number or multiple numbers and email addresses. Blocking the contact blocks all of their numbers and addresses at once. If you later want to block only one specific number from that contact while keeping others unblocked, you will need to create a separate contact entry for that number and block it individually.

Blocking from Messages

Open the Messages app and find the conversation with the person you want to block. Tap "Edit" in the top left corner, then tap the red minus sign next to their name. A menu will appear with options including "Delete" and "Block". Tap "Block" and confirm. Alternatively, swipe left on the conversation thread and tap the phone icon with a slash through it, which also blocks the contact.

When you block someone through Messages, all their text messages and iMessages stop coming through. Any existing conversation thread with them remains in your Messages app, but you can delete it if you want. New messages from them will not appear anywhere on your phone.

Blocking from Phone and FaceTime

In the Phone app, go to the Recents tab to see your recent calls. Find the person you want to block, tap the "i" icon next to their name, and scroll down to tap "Block this Caller". In the FaceTime app, find their name in your recent FaceTime calls, tap the "i" icon, and select "Block this Contact".

Blocking through the Phone app stops incoming calls and voicemail from that number. Blocking through FaceTime stops FaceTime calls and FaceTime audio calls. If you want to block someone completely across all communication methods, you should block them through the Contacts app instead, which blocks them everywhere at once.

Managing your blocked list in Settings

You can see everyone you have blocked and unblock them from Settings. Open Settings, scroll down and tap "Phone" (or "Messages" or "FaceTime" depending on which app you want to manage). Tap "Blocked Contacts" to see the full list of people you have blocked. Tap "Edit" in the top right, then tap the red minus sign next to any name you want to unblock. Tap "Unblock" to confirm.

This is also where you can check whether you have actually blocked someone if you are unsure. If their name appears in your Blocked Contacts list, they are blocked. If you do not see them there, they are not blocked, even if you deleted their messages or conversation thread.

What happens when you block someone

When you block a person on iPhone, they cannot call you, text you, or reach you on FaceTime. Their calls go straight to voicemail, and they will hear your voicemail greeting as if your phone is off or unavailable. Text messages they send appear to deliver on their end (they see a checkmark), but the messages never reach your phone and do not appear in your Messages app.

The blocked person does not receive a notification saying you blocked them. They will only realize they are blocked if they notice their calls always go to voicemail, their texts never get a response, or they try to FaceTime you and the call fails to connect. There is no way for them to know for certain from their phone that you blocked them specifically.

If you block someone and then later change your mind, you can unblock them through Settings or through their contact card. Once unblocked, they can reach you normally again, and you will see their messages and calls as usual.

Blocking unknown or spam numbers

If you receive a call or text from a number you do not recognize, you can block it even if it is not saved in your contacts. In the Phone app, tap the "i" icon next to the unknown number in your Recents list and select "Block this Caller". In Messages, swipe left on the text thread and tap the phone icon with a slash, or tap "Edit", then the red minus sign, then "Block".

You can also block a number by asking Siri. Say "Block this number" while viewing the call or message, and Siri will block it for you. This is useful if you receive a spam call and want to block it quickly without typing.

Frequently Asked Questions

Can a blocked person see that I blocked them?

No. A blocked person will not receive a notification. They will only suspect they are blocked if their calls always go to voicemail and their texts never get responses. There is no way for them to confirm from their phone that you specifically blocked them.

Will a blocked person's old messages still be visible to me?

Yes. Blocking someone does not delete your existing conversation history with them. You will still see all past messages in your Messages app. If you want to remove those messages, you can delete the conversation thread manually, but blocking alone does not erase it.

Can I block someone from calling but still receive their texts?

No. Blocking a contact blocks them across all communication methods at once — calls, texts, and FaceTime all stop coming through. If you want to block only calls or only texts from someone, you would need to use a different approach, such as muting notifications for their messages while leaving them unblocked.

What if I block someone by accident?

Open Settings, go to Phone (or Messages or FaceTime), tap "Blocked Contacts", tap "Edit", and tap the red minus sign next to their name. Tap "Unblock" to restore contact with them. Once unblocked, they can reach you normally again.

Does blocking someone delete their contact from my phone?

No. Blocking a contact does not remove them from your Contacts app. Their name, phone number, and email address remain saved. You can still see their contact card and call or text them if you unblock them later. Blocking only prevents incoming communication from them.
