if you block and then unblock someone on whatsapp, will they know?
Are you wondering if blocking and then unblocking someone on WhatsApp will alert them? Many users ask, "If I block someone on WhatsApp and then unblock them, will they know?" Understanding how WhatsApp notifications work and what the other person can see is essential for maintaining privacy and communication. In this article, we'll explore what happens when you block and unblock contacts on WhatsApp, whether the other person receives any alerts, and tips to manage your privacy effectively. Stay informed to make sure your messaging habits align with your intentions.
WhatsApp has become one of the most popular messaging apps in the world. But with all the convenience it brings, there are moments when you may need to block someone—whether it’s to avoid spam, stop unwanted conversations, or simply take a break. Naturally, this leads to a common question: if you block and then unblock someone on WhatsApp, will they know?
Let’s dive deep into this topic and uncover the truth.
Understanding WhatsApp Blocking Feature
When you block someone on WhatsApp, it doesn’t send them a flashy notification. Instead, it quietly restricts their ability to interact with you.
-
They can no longer see your profile picture updates.
-
They can’t view your “last seen” or “online” status.
-
Messages they send won’t be delivered (they’ll see only one gray tick).
-
Calls they make to you won’t go through.
In short, blocking is a digital wall—keeping your privacy intact.
The Unblocking Process Explained
Unblocking is simple:
-
Open WhatsApp settings.
-
Go to Privacy > Blocked Contacts.
-
Select the contact and tap Unblock.
After unblocking, they regain the ability to message, call, and see your updates.
Will They Know If You Block and Unblock Them?
Here’s the key answer: No, WhatsApp does not notify them if you block or unblock them.
They won’t get a message saying, “You’ve been blocked” or “You’ve been unblocked.” Everything happens silently in the background.
But—there’s a catch.
Signs That Someone Might Suspect They Were Blocked
Even though WhatsApp won’t alert them, they might notice clues:
-
Your profile picture and status updates suddenly disappear.
-
They stop seeing your “last seen” or “online” status.
-
Messages they send only show one tick (undelivered).
These signs can make them suspicious, but there’s no way for them to confirm with certainty.
What Happens After You Unblock Someone
Once you unblock them:
-
They can send you new messages (but the ones they sent while blocked will not be delivered).
-
They’ll be able to see your profile picture and status again (depending on your privacy settings).
-
They can call you again, just like before.
But they’ll never know for sure that they were blocked in the past—unless you tell them.
Common Misconceptions About Blocking
-
Do they get a notification?
No. WhatsApp never sends notifications for blocking/unblocking. -
Do past chats disappear?
No. The chat history stays intact on both sides. -
Can they see old statuses?
No. Any status you posted while they were blocked will remain hidden.
Psychological Side of Blocking/Unblocking
Blocking isn’t always about anger—it can be about self-care. Maybe you need space, or you’re avoiding negativity.
Unblocking, on the other hand, often signals a willingness to reconnect. Still, it can feel awkward. People may wonder why you disappeared and suddenly reappeared.
Think of it like locking your door for peace and later reopening it—you’re in control of your boundaries.
Privacy and Control on WhatsApp
Blocking is just one of many tools WhatsApp gives you to manage privacy. You’re not obligated to stay available 24/7. Setting boundaries is a healthy part of digital communication.
Alternatives to Blocking Someone
Sometimes blocking feels too drastic. Instead, you can:
-
Mute chats – stop notifications without cutting contact.
-
Archive chats – hide them from your main inbox.
-
Restrict privacy – limit who sees your profile info, status, and last seen.
Can They Find Out Through Third-Party Apps?
Some apps claim they can reveal who blocked you on WhatsApp. Don’t trust them.
These apps are unreliable, often scams, and may even steal your data. WhatsApp’s encryption prevents third-party apps from knowing who blocked whom.
Blocking vs Deleting a Contact
-
Blocking stops communication but keeps the number in your contacts.
-
Deleting removes their number from your phone but doesn’t stop them from messaging you.
If you want both, you’ll need to block and delete.
Blocking Across Devices
The blocking feature works the same way on Android, iPhone, and WhatsApp Web. If you block someone on your phone, it applies everywhere.
Tips for Handling Awkward Situations
If they ever ask, “Did you block me?” you don’t have to give a detailed explanation. A polite response could be:
-
“I needed some space.”
-
“I was taking a break from messages.”
-
“It wasn’t personal.”
This way, you set boundaries without unnecessary conflict.
So, if you block and then unblock someone on WhatsApp, will they know? The answer is simple: No.
They may notice temporary changes like undelivered messages or missing profile updates, but WhatsApp won’t confirm it for them. Blocking and unblocking remain private actions—your digital boundaries are yours to control.
