Blocking someone on Facebook can feel like the fastest way to create peace. Whether it’s an argument that went too far, constant spam, or simply protecting your mental space, the block button is powerful. But what happens when you change your mind?
If you’re wondering how long after you block someone on Facebook you can unblock them, this guide explains everything clearly — including the waiting period, what changes after unblocking, and what you should know before reversing your decision.
How Long Do You Have to Wait Before Unblocking Someone on Facebook?
Facebook requires you to wait 48 hours (2 days) before you can unblock someone you’ve just blocked.
That means:
- If you block someone today at 3 PM
- You cannot unblock them until 3 PM, two days later
This rule applies to regular Facebook profiles and helps prevent users from repeatedly blocking and unblocking someone within a short period.
So if you’re trying to unblock someone immediately and can’t find the option — it’s likely because the 48-hour waiting period hasn’t passed yet.
Why Does Facebook Have a 48-Hour Waiting Period?
Meta Platforms, the parent company of Facebook, introduced this rule to:
- Prevent harassment cycles
- Stop users from abusing the block/unblock feature
- Encourage thoughtful decisions before blocking
- Reduce emotional impulse actions
Blocking is meant to be a serious boundary tool — not a temporary mute button.
What Happens When You Block Someone on Facebook?
Before thinking about unblocking, it’s important to understand what blocking actually does.
When you block someone:
- They cannot see your profile
- They cannot send you messages
- They cannot tag you
- You are automatically unfriended
- You disappear from each other’s search results
Blocking completely removes digital access between both accounts.
What Happens After You Unblock Someone?
After 48 hours, you can unblock them — but here’s what many people don’t realize:
Unblocking does NOT automatically restore your previous connection.
Once unblocked:
- You are no longer friends
- They must send you a new friend request
- You must accept it
- Previous Messenger conversations remain but messaging resumes only if allowed
Also, if they blocked you back during that time, you won’t be able to re-establish contact unless they remove their block too.
How To Unblock Someone on Facebook (Step-by-Step)
If the 48-hour period has passed, follow these steps:
On Mobile (Android & iPhone)
- Open the Facebook app
- Tap the menu (☰)
- Go to Settings & Privacy
- Tap Settings
- Scroll to Privacy
- Tap Blocking
- Find the person’s name
- Tap Unblock
- Confirm your choice
On Desktop
- Click your profile picture
- Go to Settings & Privacy
- Select Settings
- Click Blocking in the left menu
- Locate the person
- Click Unblock
Can You Block Them Again After Unblocking?
Yes but keep in mind that if you unblock someone and later decide to block them again, Facebook may enforce another waiting period before you can unblock them again.
This is to prevent repeated block/unblock cycles.
Conclusion
48 hours is the waiting time to unblock someone after you block them and it is the same waiting time for everybody, nee exceptions or VIP treatment for anyone.
After that, you’re free to unblock but remember, it doesn’t automatically rebuild your connection. You’ll need to send or accept a new friend request to reconnect fully. Take your time. Make thoughtful decisions. And use the block feature wisely.
