How to block and unblock people on Facebook Messenger

Hi I’m Frankie and I would like to welcome you to my blog.

In today’s guide I will show you how to block someone on Messenger in just a few simple steps. Don’t worry, it’s an easy process that you can perform from an app on iPhone, Android, PC or Mac without needing to be an expert in IT or a geek with your smartphone.

Well, let’s get started!

There are plenty of reasons why a person would want to block someone on Messenger:

  • a difficult time with your partner
  • a broken friendship that ended badly
  • unpleasant user behavior

If you feel, for one of the reasons listed above or for any other reason, that you want to block someone on Messenger right now, then you’d better read this guide.

I’ve split it in two parts: in the first part I’ll explain how to block someone on Messenger in a few steps (and of course how to unblock them), in the second part I’ll show you what happens when you block a user, i.e. what the effects of blocking are.

I’d say not to waste any more time and proceed.

How to block someone on Messenger without them knowing

Before I show you the steps, you should know that blocking a user on Messenger means that they will no longer be able to contact you and you won’t be able to contact them either. In addition, you won’t be able to see any status updates or the last login made by the blocked person.

The procedure for preventing someone from interacting with you on Messenger is different for each operating system or device you use.

  3. A new window will appear. Tap on “Privacy” and then on “Blocked accounts
  4. Click on “add” (located at the top right) and find the contact you want to block
  5. Click on your contact name. You will see a new window with two different options: “Block Messages and Calls” or “Block on Facebook” (this second option also blocks the contact on Facebook as well as Messenger, click here if you want to know more about it)
  6. Click on “Block Messages and Calls” and confirm the action by clicking again on “Block

  1. Login to Facebook then click on “Messenger” (located on the left side)
  2. Choose among the conversations the one with the person to be blocked
  3. Click on the hole icon of i in the upper right hand corner

  5. Now, Facebook will ask you to confirm your action. All you have to do is click on “Block Messages” again.

As you’ve seen blocking a user on Messenger is within everyone’s reach. You don’t need IT skills.


Frankie’s Take:

Please remember that blocking someone on Facebook Messenger doesn’t mean blocking them on Facebook. By enabling blocking on Messenger, you will prevent that contact from chatting with you or calling you, either via Messenger or Facebook chat. However, they will continue to see your posts, comments, likes, tags, profile or any other information you post. Obviously, depending on your privacy settings. If you want to prevent this from happening you have to block it not only on Messenger but also on Facebook. I link you to the official Facebook guide.

How to unblock someone on Facebook Messenger

It’s time to show you how to unblock someone on Facebook Messenger.

Once again, the process is very simple and as far as the mobile app is concerned, it is the same for iPhone or iPad as for Android.

I’ll show it to you without wasting any more time:

  1. Log in to Messenger from smartphone apps
  2. Click on the profile pic at the top left
  3. Scroll down and click on “Privacy“. Then on “Blocked Accounts” (or “Blocked people” if you are using an Android device)
  4. Click on “Unblock” next to the name of the blocked person and then on “Unblock on Messenger
  5. Lastly a popup box will appear, click on “unblock” to confirm the operation.

Easy, isn’t it?

The process of unlocking a contact from your Desktop app is as follows:

  1. Open your app on your computer (PC or Mac)
  2. Open your chat with the blocked person and click on the three vertical dots icon
  3. Click on “Unblock on Messenger” and then again on “Unblock

Ultimately, if you want to unlock a contact from the messenger.com website, follow these steps:

  1. Log in to messenger.com or Facebook
  2. Head over to Chat and select the conversation with the person you want to unlock and click on the profile image
  3. Click on Unblock”.

Frankie’s Take:

Remember, if you decide to unblock a person, you won’t receive anything that they might have sent you while they were blocked.

What happens when I block someone on Messenger?

Well, after I showed you how to block someone on Messenger, it’s time to explain what happens after the block.

If you block someone on Messenger, they can’t send you messages

When you block someone, that person will not be able to send you messages anymore, and the same applies to you. When you open the message thread, you will no longer find the text box, camera icon, GIF icon, etc. You will be greeted by the “Something is Wrong” notification.

Can a blocked person call you on Messenger?

No, blocking a contact on Messenger stops all interaction with them. Fortunately, unlike blocking a contact on WhatsApp where the call buttons are still displayed, Messenger hides the audio and video call buttons for both parties. Still, the blocked person can call you from other apps such as WhatsApp, Telegram etc.. I wrote a guide with the most used apps for making calls and video calls. Check it out so that you can block unwanted contact on all fronts.

Does blocking someone remove the conversation?

No. Blocking someone will not remove the conversation thread anywhere. In other words, old conversations will remain in Messenger and you will be able to read them until you manually delete the chat thread.

Is online status visible for blocked contacts?

Even if you decide to keep the blocked person’s chat thread, you will not be able to see their current status or how active they are in Messenger. Neither will the blocked person be able to do so.

What happens to stories?

Facebook and Messenger stories are similar but different. When you block someone on Messenger, the blocked person won’t be able to see your Facebook and Messenger stories. So if you post something on the Facebook story, where you haven’t blocked the person, the blocked contacts won’t be able to see them either. Likewise, you won’t see the blocked person’s history on Facebook or Messenger.

Can you interact with past messages?

If you open the thread of a blocked person’s conversation, you will notice that the reaction button is still visible. Tapping it will show you the reactions. However, tapping one of them will notify you that you need to unblock the person first.

What happens to groups?

Group chats remain unaltered if you block someone. You will both be able to see each other’s messages in common groups. However, Facebook lets you know when you enter a group in which there is a person you blocked on Messenger as a precautionary measure.

Does the blocking of the contact get notified?

No. The other person will not be notified of any kind. However, they will lose the ability to send you messages or call you as we saw above and from this they will realize that they have been blocked.

Blocking a contact: difference between Messenger and Facebook

Blocking someone on Facebook or Messenger is not the same thing. From the very beginning, when you press the block button on Messenger, you will be asked if you want to block only their messages or block them on Facebook as well.

The former will block the contact only on Messenger with everything you’ve seen so far about what blocking involves. This will have no effect on your Facebook profile. That is, you will still be able to view the contact’s profile on Facebook (you will remain friends) and interact with it (comments and likes). Only when you block them on Facebook, you will lose access to their profile and other interactions on Facebook including Messenger.

How to know if someone blocked you on facebook messenger?

I have been asked this question lots of times! I have good news for you. There are some ways to know if you have been blocked on Facebook Messenger. I have written a guide entirely focused on this topic. I suggest you to take a look at it, here’s its link: 7 tips to know if someone blocked your Messages on Facebook.

How to know if someone blocked you on facebook messenger?

Unfortunately you cannot block messages received from unknown people. However, I would like to show you a trick to prevent them from texting you several times: after you receive the first message from the person who is not your friend, just block them! This way they won’t be able to text you again. In the past (until 2019) it was possible to avoid receiving messages on Messenger from non-friend people. I honestly don’t understand why Facebook removed this option.

Does blocking someone on facebook messenger keep them from spying on my account?

No, it doesn’t. If someone is spying on your account, it means your Messenger has been hacked. In order to protect yourself, I recommend learning how Messenger’s accounts can easily be hacked.

What happens to old posts and comments when i block someone?

When you block someone on Facebook, your old comments and posts are hidden from their view. Likewise, their posts, comments, likes and so on will vanish from your feed. In short, everything you and the blocked person have shared disappears. However, any other user on Facebook can still see those things.

What happens to old messages exchanged with the blocked person on Facebook Messenger?

When you block someone on Facebook, all the messages you’ve exchanged won’t automatically disappear from Messenger. However, you won’t be able to chat further with that person except in common group conversations.

Will blocked people be able to search for your profile on Facebook?

No. Your profile will never appear in Facebook search results to those who have been blocked. It goes without saying that if you look for the blocked person on Facebook, they too will not appear in your search results.

Can blocked people search for your profile on google?

If a blocked user searches for your name on Google, your profile link (URL) will come up only if they are NOT logged in on Facebook. If they are, they will not be able to see your profile.
