How to Unblock Someone on Facebook (2026 Desktop and Mobile Guide)

Blocking someone on Facebook is easy — and so is changing your mind. Whether you blocked a person in the heat of the moment or simply no longer need the distance, unblocking takes only a few taps. This guide shows exactly where the block list lives on desktop and mobile, explains what actually happens when you unblock someone, and covers the quirks worth knowing, like Messenger's separate settings and Facebook's short waiting period.

What happens when you unblock someone

Unblocking simply lifts the wall between you. The person will be able to see the parts of your profile you share publicly and interact with you again, just like any other user. What unblocking does not do is restore your previous connection: if you were friends before, you won't be automatically re-friended — one of you has to send a fresh friend request. The other person is never notified that they were blocked or unblocked, so the change happens quietly.

How to unblock someone on desktop

1. Log in at facebook.com and click your profile picture, then Settings & privacy → Settings.
2. In the left menu, choose Blocking.
3. Find the person in your Block users list.
4. Click Unblock next to their name.
5. Confirm when Facebook asks — they're now unblocked.

How to unblock in the mobile app (Android and iPhone)

1. Open the Facebook app and tap the menu (three lines).
2. Tap Settings & privacy → Settings.
3. Scroll to the Audience and visibility section and tap Blocking.
4. Find the person under blocked users and tap Unblock.
5. Confirm your choice to remove them from the block list.

Unblocking on Messenger is separate

Facebook and Messenger keep their own block lists, so unblocking someone on Facebook doesn't automatically let them message you again. If you also blocked their messages, open Messenger, go to that person's conversation or your Messenger privacy settings, find the blocked contacts list, and unblock them there too. It's common to have someone blocked in one place but not the other, so check both if you want a clean slate.

The 48-hour rule

Facebook adds a small guardrail to prevent block-and-unblock games: once you unblock someone, you generally can't block them again for about 48 hours. It's worth being sure before you unblock, because you won't be able to immediately reverse course. If the person was a friend and you want that back, remember you'll also need to send a new friend request, since unblocking alone doesn't restore the friendship.

Unblock, unfriend, or restrict?

If full blocking feels too strong but you still want distance, Facebook offers gentler tools. Unfriending removes the connection without blocking, so you can still see each other's public posts. Restrict keeps someone as a friend but limits them to only your public content, without them knowing. Understanding these options helps you pick the right level of separation instead of relying on blocking for everything.

Frequently asked questions

Will the person know I unblocked them?

No. Facebook never notifies anyone that they were blocked or unblocked, so the whole thing stays private.

Does unblocking make us friends again?

No. Unblocking only removes the block. If you were friends before, someone needs to send a new friend request to reconnect.

Why can't I block them again right away?

Facebook enforces a roughly 48-hour cooldown after unblocking before you can re-block the same person.

I unblocked them but still can't get messages — why?

Messenger has its own block list. Unblock the person in Messenger separately to restore messaging.

Final thoughts

Unblocking someone on Facebook is quick and completely private, whether you do it from a browser or the app. Just remember the two catches: check Messenger's separate block list if messaging matters, and know that you can't re-block for about two days. Beyond that, if you want to rebuild the connection, a simple new friend request is all it takes.
