Here’s a clear, user-friendly guide on how to block texts on iPhone , along with some extras like filtering unknown senders and dealing with spam.

Blocking a specific texter in Messages

Use this when someone is texting you and you want them fully blocked (texts, calls, FaceTime).

  1. Open the Messages app on your iPhone.
  1. Tap the conversation with the person/number you want to block.
  1. At the top, tap the name/number/profile icon.
  1. Tap Info (you may need to tap Info again on the next screen).
  1. Scroll down and tap Block this Caller (or Block Caller / Block Contact).
  1. Confirm by tapping Block Contact.

Once blocked, that person’s texts, calls, and FaceTime will no longer come through to you.

Blocking someone using Contacts / Phone

Good if you’ve deleted the text or want to preemptively block a number.

  1. Open the Phone app and go to the Contacts tab.
  1. If the person is already a contact:
    • Tap their name , scroll to the bottom, and tap Block this Caller , then confirm.
  1. If they aren’t a contact:
    • Tap the + button to create a new contact.
    • Add a name and phone number , tap Done , then scroll down and tap Block this Caller.

This blocks texts, calls, and FaceTime from that number as well.

Filtering unknown senders (semi-automatic filter)

If you’re getting a lot of spam or random codes, you can have iOS separate unknown numbers into a different list.

  1. Open Settings.
  1. Scroll down and tap Messages.
  1. Scroll to Message Filtering (near the bottom).
  1. Turn on Filter Unknown Senders.

What this does:

  • Messages from numbers not in your contacts go into an “Unknown Senders” tab instead of your main list.
  • You can view them by tapping Filters → Unknown Senders at the top of the Messages list.

Caution: you could miss an important text from a new number if you forget to check that tab regularly.

Extra tips for spam and scam texts

  • Never tap suspicious links or share personal info (codes, passwords, bank details).
  • For obvious spam, you can often tap Report Junk (if shown) in the message thread; this helps your carrier and Apple flag that sender.
  • Combine blocking + Filter Unknown Senders for a much cleaner inbox, especially if you’re getting lots of promotional or robocall-type texts.
