How to Block a Contact in a Messaging App

Tap through each step to see how to block someone from messaging you.

  1. Open the person's profile

    Go into their profile from your contact list or from an existing chat with them.

  2. Open the options menu

    Tap the menu icon, usually in the top corner of their profile screen.

  3. Select "Block" and confirm

    Choose "Block" from the menu and confirm the action when prompted.

  4. Optionally hide them from your contact list too

    Some apps offer a separate "hide" option alongside blocking, which removes them from your visible contact list without any notification to them either.

  5. Unblock them later if you change your mind

    A dedicated "blocked contacts" list in settings lets you review and unblock anyone at any time.

A quiet way to stop unwanted contact

If messages from someone have become unwelcome, blocking stops new messages from reaching you without sending them a direct notification that they've been blocked.

Blocking is stronger than just deleting a contact

Removing someone from your contact list only takes them out of that list -- they can generally still message you afterward. Blocking is a stronger step that actually prevents new messages from getting through at all.

Frequently Asked Questions

Can the other person tell they have been blocked?

There is usually no direct notification, though changes like their messages no longer showing a delivery confirmation, or an outdated profile photo, can sometimes tip them off indirectly.

What is the difference between blocking and removing a contact?

Removing a contact just takes them off your list, but they can still message you; blocking actively prevents their messages from reaching you at all.
