When you unblock someone on Facebook, they will:

Before we dive into the unblocking process, let's quickly discuss why you might block someone on Facebook in the first place. You may block someone if:

For users accessing Facebook via a desktop computer or laptop, the process is straightforward. First, one must navigate to the top right corner of the screen and click on the profile picture or the downward-facing arrow to access the "Settings & Privacy" menu. From there, selecting "Settings" opens a new array of options. On the left-hand side of the screen, under the "Audience and Visibility" section, the user will find "Blocking." Clicking this link reveals a list of all currently blocked users. Next to each name is an "Unblock" option. Upon clicking this, a pop-up window will appear asking for confirmation. Once confirmed, the user is immediately unblocked, though it may take a few hours for all permissions to fully restore.

However, the technical process is only half the story. Unblocking does not automatically restore the friendship to its former state. Before you blocked someone, you were presumably connected as friends. After you unblock them, you are simply two strangers who can see each other’s public content again. To re-establish the digital bond, you must send a new friend request. This is Facebook’s quiet way of ensuring that unblocking is a deliberate act, not an accidental erasure of boundaries.

Furthermore, there is a timing constraint that often catches people off guard. Facebook imposes a 48-hour waiting period after unblocking someone before you can send them a new friend request. This "cooling-off" period is a wise feature. It prevents the emotional whiplash of blocking and unblocking in the heat of the moment. It forces you to wait, reflect, and ask yourself if you truly want this person back in your digital life.
