A Messenger block's duration depends on who initiated it: if you block someone, it lasts indefinitely until you unblock them (with a 48-hour re-block cooldown after unblocking); if Meta temporarily blocks you for violating standards, it can last from hours to 30 days, varying by severity, but you'll know the duration when it happens.
The length of a temporary block by Facebook depends on the severity of the violation and the user's history on Facebook. It has been observed that a temporary block may last as little as a few hours, but could also last up to 30 days. There is currently no way to view the duration of the block.
How to Identify If You're Blocked on Messenger. Messages not showing 'Delivered' and inability to see profile updates often indicate blocking. If your Messenger messages no longer show 'Delivered,' it may mean the recipient blocked you. Other signs include missing profile pictures or status updates.
When you block someone's Facebook profile on Messenger, it also blocks their profile on Facebook. They won't be able to message, call or find your profile on Messenger or Facebook chat. If you're Facebook friends, blocking them also unfriends them. Profiles won't be notified when you block them.
While there's no infallible way to confirm if you've been blocked, there are various other signs that you can look out for. Their profile picture has disappeared and you see a default one instead. You can't start an audio or video call with the person. Their online/active status isn't visible to you.
Use Anonymous Texting Services
And the best thing about these anonymous texting services is that they work even if you are blocked. You can simply visit it, enter the receiver's number, and send any text of your choice completely for free.
If you unblock someone's Facebook profile on Messenger: You'll also unblock them on Facebook. Unblocking a profile won't add them as a Facebook friend again. You won't be able to block them again for 48 hours.
No, you cannot see who specifically views your personal Facebook profile or page, and any third-party apps claiming to offer this are fake and potentially harmful; however, for business Pages, you can see general visitor numbers in Meta Business Suite, and you can infer activity from who interacts with your posts, but you can't see lurkers.
What happens when a blocked number texts you? A blocked person can't reach you via text. Technically, they can still send an SMS message to your phone number, and they'll see the regular delivery status at their end, just like with any other texts they send.
Check the color of your messages.
If it is green that could be a sign your messages have been blocked: iMessages are sent over the internet and appear in blue bubbles when sent between iOS users, while SMS messages are sent through your carrier and appear green.
If you can still see this person's profile photo and name at the top of the chat, the user has not deactivated or deleted their account—you could still be blocked. But if their profile photo is now a gray outline of a person instead of their old photo, they've likely deactivated their account, not blocked you.
To know if someone blocked you, watch for calls going straight to voicemail after one ring, texts showing "Not Delivered" (or no read receipts/checkmarks on apps like WhatsApp), and potential changes on social media; the most definitive test is calling from another number, where it rings normally for you but goes to voicemail on your original number, indicating a block.
If you find yourself in a situation that feels unsafe for any reason, don't hesitate to use the “block” function, Gottsman says. Not only will this unfriend a person, but it will also prevent them from sending you future requests or messages or even seeing your profile.
Facebook enforces a 48-hour waiting period before you can reblock someone to prevent misuse of the blocking feature. This cooldown helps reduce harassment and spam. If you see this notification, wait the full period before attempting again. To manage blocked users, access Settings > Privacy > Blocking.
Even if they blocked you, you would still have their contact, just unable to text or call them.
No, people can't see if you look at their profile.
Some users suggest that you'll appear on a user's "People you may know" friend suggestion if you look at a person's profile. Others suggest it only appears if you have your location services on and your devices appear online nearby one another.
No, Facebook doesn't tell people that you've seen their profile.
Facebook doesn't let people track who views their profile. Third-party apps also can't provide this functionality.
Just as blocking carries deep psychological meanings, unblocking someone is rarely a neutral act. It often signals a shift in emotions, attitudes, or circumstances that prompts a reevaluation of previous boundaries. Unblocking can represent forgiveness or a willingness to re-engage.
If the person you're calling has blocked anonymous calls, *67 won't work either. While *67 hides your number from the person you're calling, phone companies can still trace the call.
