How to block someone on iPhone

The short answer

Open the Phone app, find the number you want to block, tap the info icon, scroll down, and tap “Block this Caller” — this blocks calls, texts, and FaceTime from that person.

How to block someone from the Phone app

This is the fastest method:

  1. Open the Phone app and tap Recents
  2. Find the number or contact you want to block
  3. Tap the info icon (the small “i” in a circle) next to the number
  4. Scroll to the bottom and tap Block this Caller
  5. Tap Block Contact to confirm

Once blocked, that person cannot call you, send you texts, or FaceTime you. They won’t be notified that you blocked them.

How to block someone from Settings

If the person hasn’t contacted you recently:

  1. Go to Settings > Phone > Blocked Contacts
  2. Tap Add New at the bottom
  3. Search for and select the contact you want to block

This same method works under Settings > Messages and Settings > FaceTime.

Changed your mind? Here’s how to reverse it:

  3. Tap Unblock

What happens when you block someone?

  • Phone calls from them go straight to voicemail
  • Text messages they send are not delivered to you
  • FaceTime calls from them won’t come through
  • They won’t get any notification that they’ve been blocked
  • Their calls will still appear in your blocked voicemail folder at the bottom of the Voicemail tab

Blocking someone does not remove them from your contacts list — it just stops their communications from reaching you.
