How to Unblock Someone on Facebook
Find your blocked-profile list, review what unblocking changes, and confirm only when you are ready.
Open Menu, Settings and privacy, Settings, and scroll to Audience and visibility. Tap Blocking, find the profile, and tap Unblock. Read the confirmation carefully, including Facebook's temporary 48-hour restriction on blocking that profile again, then confirm.
Before you start
Unblocking may allow the person to see your Timeline or contact you, depending on your privacy settings. Facebook's current confirmation also says earlier tags may be restored and that you must wait 48 hours before blocking the same profile again.
Follow the steps
Open Blocking settings
Tap Menu, expand Settings and privacy, and tap Settings. Under Audience and visibility, choose Blocking.
Find the blocked profile
Review the blocked-profile list and tap Unblock beside the correct name. Check the profile carefully before continuing.
Review and confirm
Read what may change, including restored contact access, possible restored tags, and the 48-hour wait before blocking again. Tap Unblock to confirm or Cancel to keep the block.
A couple of useful details
Will Facebook notify the person?
Facebook does not show a notification warning in the reviewed flow, but the person may notice that they can find or contact your profile again.
Can I block the person again immediately?
No. The current Facebook confirmation says you must wait 48 hours before blocking that profile again.
Does unblocking add the person as a friend?
No. Unblocking does not automatically restore a Facebook friendship. You would need to send or accept a new friend request.
Can previous tags return?
Facebook's confirmation says tags you previously added to each other may be restored.
