You blocked someone on WhatsApp. Then later, you unblocked them. Now you’re wondering. Will they know?
Will they see your profile again? Will your messages go through? Will it be awkward?
You’re not alone. A lot of people feel the same confusion. WhatsApp doesn’t send alerts about blocking or unblocking.
But it leaves behind clues. And if the other person notices, they might figure it out.
Let’s break it all down in plain English. No confusion. No guessing. Just real answers you can use.
Can someone tell if you’ve blocked and then unblocked them?
WhatsApp won’t tell them directly. No alert. No pop-up. No “You’ve been unblocked” message.
But… they still might know. And that’s because of some small but noticeable changes.
1. Your profile photo becomes visible again.
If your picture was missing for days or weeks and then suddenly shows up again, that can raise eyebrows.
Especially if they remember it disappearing when things got tense. People notice these things more than you think.
2. Your “last seen” and online status reappear.
Let’s say they used to check when you were last online, and it was always blank.
Then, one day, your “last seen today at 10:05 AM” suddenly appears. That’s a big clue. It doesn’t take much for someone to connect the dots.
3. Your status updates show up again.
If they haven’t seen your WhatsApp stories in a while, and now your updates pop up again, it’ll look suspicious. Even a single “Good Morning” story can give you away.
4. Their messages start delivering.
This is the clearest sign. When someone’s blocked, their messages only show one checkmark, which is “sent“, but not delivered.
The moment you unblock them, those messages will get two ticks. Delivered. That’s the confirmation they were waiting for.
So, technically, no. They won’t get told. But in reality? If they’re paying attention, they’ll probably figure it out.
Blocking and unblocking leave traces. Even if it’s subtle, someone who’s looking will notice.
What happens if you keep blocking and unblocking someone?
Technically? You can do it as many times as you like. WhatsApp won’t stop you. There’s no limit.
But emotionally? That’s a different story.
Constant blocking and unblocking send mixed signals. It can hurt trust and confuse the other person. They might feel like they’re walking on eggshells.
What would I suggest instead? If you just want space, try this instead:
If you just want space, try this instead:
- You can mute the chat. You won’t get notifications, but you stay connected.
- You can also archive the chat. It hides the conversation until there’s a new message.
- You can turn off read receipts or last seen. You get privacy without conflict.
Use blocking only when necessary. Not as a quick reaction.
Will you get messages sent during the block?
No. You won’t get any messages that were sent while the person was blocked.
Those messages are gone. Yes, forever. They don’t sit in a folder. They don’t get delivered after unblocking. They’re just lost.
Think of blocking like shutting the door. Whatever they say while it’s shut, you’ll never hear.
If you’re really curious, you’ll need to ask them to resend. That might be awkward. But it’s the only way.
Can you read messages from someone you’ve blocked?
Nope. You can’t.
Once someone is blocked, their messages can’t reach you at all. Even if they send them, you won’t see them. Ever.
There’s no secret inbox. No hidden section. No trick to read what they wrote.
Blocking = total silence.
Unblocking just opens the door again. But only for new messages.
What if you can see someone’s online status? But think you’re blocked?
I have some good news again.
If you can see their online status, then you’re not blocked.
Because when someone blocks you on WhatsApp, you can’t see their:
- Their profile photo
- And, their online or last seen
- And, their status updates
- And, if your messages are delivered
So if you’re seeing some of these, you’re probably fine. And they have not blocked you yet.
And if you are still unsure? Just check these. If you can see these, it means you are fine my dear.
- Can you see their profile photo? ✅
- Can you see their last seen or online? ✅
- Do your messages show two blue/gray ticks (delivered)? ✅
If yes to any of these, you’re not blocked.
If not, then you might be. Or they’ve changed their privacy settings. Or their phone’s off. Don’t jump to conclusions too fast.
How many times can you block and unblock someone?
I have some good news for you. It’s unlimited times.
There’s no rule stopping you from doing this over and over.
But that doesn’t mean it’s always a smart idea.
Doing this repeatedly can damage your relationship with the person. Because trust works both ways.
Blocking and unblocking can create tension or distrust. I get it. It happens often between couples who are emotionally attached to each other.
So, if you catch yourself blocking and unblocking someone often, pause for a moment.
Ask yourself:
What am I really trying to do? Is there a better way to handle this?
Sometimes, a conversation solves more than a block ever could.
What happens to “last seen” after unblocking?
When you unblock someone, your “last seen” visibility depends on their privacy settings.
Here’s how it works:
- If they’ve allowed last seen visibility, you’ll see it again.
- If they’ve hidden it, you still won’t see it. Even after unblocking.
Also, they might see your last seen and online status again if you’ve allowed it in your own settings.
So don’t expect things to go back to how they were. Unblocking doesn’t override privacy choices.
It just opens the door. What they let you see is still up to them.
Signs someone has unblocked you on WhatsApp
Want to know if you’ve been unblocked?
Here’s what usually changes:
- You can see their profile picture again
- Your messages start showing two ticks
- Calls begin to ring or go through
- You can view their status and “about me”
If you’ve noticed these things. Congrats. You’re likely unblocked.
Again, WhatsApp won’t tell you. But these clues are hard to miss.
The takeaway
You now know exactly what happens when you block and unblock someone on WhatsApp.
Let me recap a little. No notifications will ring, but they’ll probably notice the shifts. Messages you sent while blocked are gone forever. Luckily, on WhatsApp, there’s no limit on blocking or unblocking.
However, trust can take a hit. Noticing online status indicates you’re not blocked. Unblocking doesn’t override those pesky privacy settings.
Blocking is like slamming the door shut. Unblocking is like opening it again. But only for future messages. If you want peace without drama, consider muting or archiving instead.
Before you tap “Block,” pause. Could an honest conversation fix things better?
Use the tools wisely. They’re powerful. And they affect real people.
You’ve got the knowledge now. Use it well.
