How to Make a Checkmark Symbol in Facebook

By Jill Lee

Using alt code symbols -- small pictures made by pressing the "Alt" key on your keyboard and a number code -- on Facebook is one way to make your posts stand out. Making a check mark to post in your status update or even add to your information is a simple code you can type from almost any keyboard. The check mark made with an alt code is actually a square root symbol, making it useful for posts mathematical in nature as well.

Step 1

Click inside the text box where you want to place the check mark.

Step 2

Hold down the "Alt" key on your keyboard.

Step 3

Type in "251" using the number pad on your keyboard.

Tips & Warnings

  • Number lock must be turned on to make alt codes.
