How to Block Someone on Facebook on Phone or Computer

The quickest way to block someone on Facebook is to open the person's profile, select the three-dot menu, choose Block, and confirm. You can do this in the mobile app or a desktop browser. Facebook does not normally notify the person that you blocked them.

Blocking limits interaction between the profiles, but it does not erase previous messages or guarantee complete invisibility. You may still encounter each other's activity in shared groups, apps, public posts, or conversations involving other people.

What Facebook blocking changes

• The blocked profile can no longer start ordinary Facebook interactions with your profile, such as tagging or adding you as a friend.
• If you were friends, blocking removes the friendship.
• Past message history can remain in both inboxes.
• Blocking a profile is different from blocking only its messages and calls in Messenger.
• Shared groups and public content can create limited exceptions to what each person can see.

Block someone from their profile in the Facebook app

1. Open the person's Facebook profile.
2. Tap the three-dot menu below or near the profile name.
3. Select Block.
4. Read the confirmation and tap Block again.

Blocking on Facebook vs. blocking in Messenger

If you block only messages and calls in Messenger, the person can still see and interact with your Facebook profile according to its privacy settings. If you block the Facebook profile, broader Facebook interactions are restricted as well. Review the wording in the confirmation dialog so you know which action you are taking.

For spam, impersonation, threats, or harassment

Blocking protects your interaction but does not automatically report the account or content. Use the Report option on the profile, message, post, or comment when it may violate Facebook rules. Preserve screenshots and links before blocking if you may need evidence.

For a credible threat or immediate danger, contact the appropriate local emergency or law-enforcement service. Do not rely on a platform block as the only safety measure.

How to unblock someone

Return to Settings > Blocking, open the blocked list, and choose Unblock beside the profile. Facebook may impose a waiting period before the same profile can be blocked again, and unblocking does not automatically restore the friendship.
