How to Block Anyone from a Facebook Group (even if they aren’t in it)

Have a Facebook group and need to block someone, but they aren’t actually a member of the group? Here’s how to block anyone from a Facebook Group, even if they aren’t in it!

Hey y’all, Tiffany here.

This post is really different from what I usually right, but I felt like this was really important for anyone who is an admin of a Facebook group, especially a public group.

As you may know, I have an Amazon deals group that I kept from back when I was a coupon blogger.

Lately, it seems like the group has been flooded with spammers. Usually I just block them from the Facebook group. But these spammers reply to comments for people to join their own group, then leave so they can’t be blocked and have all of their comments deleted at once.

We also have issues with people who are admins of other deals groups stealing our deals – sometimes they copy and paste word-for-word! Amazon requires deals groups to be public groups, so people see all of the posts whether they are members or not.

Unfortunately, it isn’t easy to block people who aren’t actually members of the group. Facebook doesn’t have anything in their Help Center about it.

I did some digging, and I was finally able to come up with how to block anyone from a public Facebook group, even if they aren’t a member! (This may not work on private or secret groups.)

How to Block Non-Members from a Facebook Group

Please note that this trick to block non-members from a Facebook group only works for administrators of a group. Moderators will not be able to do this.

Step 1 – Group ID

Find your group ID number. You can find it in the URL of your group:

block facebook group

Step 2 – Profile ID

Find the ID number of the person you want to block from your Facebook group. You find this by going to their profile and looking at their URL:

block facebook group nonmember

Some don’t have a number on the end, like this one below. If that happens, you can find that user ID here.

block facebook group who isn't a member

Copy and paste this link below. You must leave it in mobile format (with the m. in the front) for it to work. You can do this on a desktop or a phone, however.

Replace the 11111111 with your group ID number, and the 2222222 with the profile ID number.

Step 4 – Block them!

Copy and paste the URL you created with the numbers into your computer browser (this may not work on a phone). You should then get a screen asking you if you want to block them from your Facebook group.

(If you removed the m. at hte beginning, you will get a broken link screen instead.)

block facebook group

Click “Confirm.” Now, the screen may load for a minute, but then it will go back to the same look. It will not actually change from this view with a confirmation, but it should have worked. (I click confirm about 5 times for good measure.)

You can double-check by going back to your group and seeing the Blocked Members.

You’ve Done a Facebook Group Block!

Congratulations! You’ve now blocked someone from your Facebook group who isn’t actually a member of the group!

Hopefully this post will help you with your own Facebook groups in the future.

  1. Thank you it worked. I didn’t know what browser you meant. I just tried putting the URL everywhere 😂 not sure which one exactly blocked them but their activity is gone. Hoping you can explain exactly where you’re talking about pasting the link in the browser

      1. I can’t get it to work for me. It says the link may be broken or the page removed. Help!

          1. It didnt work for me either, it gives me page error, what happens when you dont have the ID number and instead just have the names in the links? I put in the name in my group link and name of the profile link and it didnt work. any thoughts?

          2. You cannot use the name – it HAS to be the number. I gave a link above in the post on a website you can go to where you put the URL for the person’s page in and get the number. Please re-read it carefully.

        1. Is it someone you have personally blocked prior ? Because it didn’t work until I unblocked the person from my personal account.
          Now i have to wait 48hours to block them back

        2. it works for me every time. To easily get the person’s profile or page id so you can block it I simply copy and page the profile or page URL into the box and the top press the “look up” button and bingo, in a few moments you have the id. <3

      2. Hello Tiffany! Thanks for this! I have done this successfully, however do you have a post of how to undo the block? I tried undoing the activity on the group page or looking for the member that I have blocked but there is no button that says unblock :(. Please help! thank you!


        1. Great question! From my desktop, I can go to “members” and filter to “blocked.” Then next to their name, there are 3 dots and I can choose “Unblock” from that.

  2. Works for me! Thankfully it blocks those pesky jerks who have a hard time letting go/getting the boot. Thank you for saving me from more aggravation!

  3. This worked! When I went to confirm the block (using a laptop but the mobile URL you provided), nothing happened but when I returned to my group, the person was on the blocked list. Thank you so much. Very valuable!

  4. I’m using MS Edge; I declined a membership request /never added the person and I can’t use your method to block them. Your provided URL with the correct group & profile numbers gave me an error saying “there was an error REMOVING member from the group”, versus blocking them. Thanks for any help.

    1. You should be able to go back in your Activity Log and find where you removed them and undo it.

    1. Yes, it is still working. I literally just tested it before responding to your comment to make sure.

      You need to be an admin of the group you’re blocking.
      You must use the numbers for the group and the person (not their usernames)
      Even after you click “confirm” it won’t look like anything happened, but you can go back to the group and check the blocked members list.

  5. Not currently working. Am an admin of the group, used the ID numbers from both the group and several different people to test and all gave a content not found broken link Facebook page, which I sifted through and can’t find anything in the code about blocking. Has something changed about this process very recently? I did get all numbers and the link correct.

    1. I just tried it again and it still works. Usually the broken link FB page means you did it on a phone instead of a laptop/desktop computer.

      1. I’ve been using a desktop.
        Does the group status matter? Mine is currently private- does it need to be public?

        1. That’s an excellent point – it probably needs to be a public group. I’ve only ever tried it with my public groups because my private groups no one can see the content unless I actually add them.

  6. This is helpful. We had a stalker of an employee on our business page. We blocked him there but wanted to prevent him from trying to join the groups attached to our page.

    Note: I had to look up the actual user id and group id, not the username or group name, which is what shows up in the link. Also, Tiffany is correct, it didn’t look like anything happened after I clicked “Confirm” but he was listed under “Blocked” in the group.


  7. I’ve used this on quite a few occasions but it doesn’t seem to be working now. It doesn’t acct any different, but when I check the blocked member list, the person I just tried to block isn’t on it. Any ideas on how to still make it happen?

    1. I just tested it after I saw your comment, and it worked for me. Perhaps try clearing your cache/cookies for your web browser? You might also try pressing “Confirm” several times in a row to see if that works.

        1. I’m sorry, I’m afraid there isn’t much more I can offer, then. 🙁 I’m not a Facebook guru or a tech person, just a blogger who happened to stumble on this and wanted to share it.

  8. This works perfectly, I just blocked several people from my group tonight.

    Copy her link above with the “111’s” and the “222’s” I did this in a word document to make sure the numbers were correct.

    Use the link to the “find that user ID here.” which she provided near the end of step 2
    To do that paste your group link in the box then hit “find id” then do the same for the person you want to block. You have to go to the pages to get the links to put in the box. If you don’t get the ID refresh the page a time or two. It’s freeware and can be cranky.

    First find your group ID then paste it over the ones in the formula
    Second find the person’s ID then paste it over the twos in the formula
    Paste the formula in your browser then hit enter.

    A tiny photo will show up asking you to confirm the block, hit confirm.

  9. I got the profiles id’s and followed the instruction. Unfortunately shows that The link you followed may be broken, or the page may have been removed.
