How to Block Strangers From Finding You on Facebook

Facebook offers privacy settings that let you control your level of visibility on the social media platform. Depending on how much privacy you want, use these settings to control who sees your posts or presence on Facebook. Here's how to not let anyone find you on Facebook by customizing your settings so that you don't show up in a Facebook search.

This information covers customizing your Facebook privacy and visibility with Facebook on a desktop as well as in the Facebook mobile app.

How to Adjust Who Can See Your Facebook Posts

Facebook lets you make your posts as visible or invisible as you like. Here's how to adjust who can see your Facebook posts.

Select Only me to hide posts from everyone except yourself.
Select More to choose Specific friends, which allows you to choose who sees your posts, or Custom, which allows you to include or exclude certain friends.
After you make your adjustments, select Close in the upper-right corner of the Your Activity window.

To restrict access to previous posts, go to Privacy > Your Activity. Next to Limit the audience for posts you've shared with friends of friends or Public?, select Limit Past Posts and follow the prompts.

Adjust How People Can Find You and Contact You

Facebook allows you to set boundaries on who can find you, send you messages, and access your Facebook profile. Adjust these settings to make yourself as open or invisible as you like.

Adjust Your Visibility Using Facebook on the Desktop

On your Facebook home page, select the Account icon (the down arrow) in the upper-right corner.
Select Settings & Privacy.
Select Settings.
From the left menu pane, select Privacy.
Under Privacy Settings and Tools, go to How People Find and Contact You, then select Edit next to Who can send you friend requests?

The default is Friends of friends.
Select the drop-down arrow next to Friends of friends (or your current setting).
Select Everyone to allow anyone to send you a friend request, or keep the default Friends of friends setting. Select Close after you make a selection.
Next to Who can look you up using the email address you provided?, select Edit.

The default is Friends.
Select the Friends (or your current setting) drop-down arrow.
Select Everyone, Friends of friends, Friends, or Only Me. Select Close after you make a selection.

Select Only me for the highest privacy level.
Next to Who can look you up using the phone number you provided?, select Edit.
Select the Only Me (or your current setting) drop-down arrow.
Select Everyone, Friends of friends, Friends, or Only me. Select Close after you make a selection.

Select Only me for the highest privacy level.
Next to Do you want search engines outside of Facebook to link to your profile?, select Edit.
Clear the Allow search engines outside of Facebook to link to your profile check box if you want search engines to stop linking to your profile. Tap Turn off in the warning box to confirm. Select Close after you make your selection.

If you adjusted your privacy settings and a stranger or undesirable person contacts you, consider blocking that person on Facebook to eliminate any chance of future contact.

Adjust Your Visibility Using the Facebook App

Select Everyone, Friends of friends, Friends, or Only me.

Only me is the most private option.
