You can block a phone number from recent calls, Messages, or a saved contact. Blocking helps stop normal communication through Apple’s Phone, Messages, and FaceTime features from that contact or number.
Block a Number From Recent Calls
- Open the Phone app.
- Tap Recents.
- Tap the information button beside the number.
- Tap Block Caller.
- Confirm.
Block a Sender From Messages
- Open the conversation.
- Tap the sender information at the top.
- Open the person’s details.
- Choose Block Caller.
Review or Unblock Numbers
Go to the blocked-contacts controls in the Phone settings to review the list. Removing someone from that list allows future supported communication again.
What Blocking Does Not Do
Blocking does not erase the contact or previous messages. It also does not automatically configure block lists inside unrelated third-party calling or messaging apps.
Spam From Constantly Changing Numbers
If spam callers keep using new numbers, individual blocking becomes less effective. Unknown-caller screening and carrier spam filtering may be more useful for that situation.
Blocking Does Not Prove a Caller Is Gone
Phone numbers can be spoofed, reassigned, or changed. Blocking a displayed number prevents normal contact from that entry, but it does not stop a scammer who starts calling from different numbers. For persistent abuse or fraud, combine iPhone controls with your carrier’s spam tools and keep records if the calls may need to be reported.
Unblocking Is Reversible
You can remove a number from the blocked list later if the situation changes. Before unblocking, verify that the contact information belongs to the person or organization you actually intend to allow again.
