How to Tell If Someone Blocked You on WhatsApp: 5 Subtle Signs You Should Check

how do you know if someone blocked you on WhatsApp

It’s happened to most of us you send a WhatsApp message, and days go by with no reply. You start wondering, Did they block me? While WhatsApp doesn’t send a pop up saying “You’ve been blocked” (imagine the drama), there are a few signs you can watch for.

The tricky part? None of these clues are 100% conclusive. Sometimes, slow internet, privacy settings, or even someone deleting their account can look a lot like a block. Still, if you notice several of these signs together, it might be a hint.

Here’s what to look out for.

1. Their “Last Seen” or “Online” Status Vanishes

If you used to see when they were last active or that little “online” tag at the top of the chat, but now it’s gone, that could mean they’ve blocked you. Of course, they might have just changed their privacy settings to hide this info from everyone or just from you.

2. Profile Picture Stops Updating

One of the first things people notice when blocked is that the other person’s profile photo disappears or freezes in time. If their picture used to change regularly but now it’s stuck (or completely blank), that’s worth noting. Still, they might have simply removed their picture altogether.

3. Messages Stuck on One Check Mark

Here’s a big clue:
  • One gray check mark - sent, but not delivered
  • Two gray checks - delivered
  • Two blue check - read

If your messages never get past that single gray check mark, it could mean they’ve blocked you or their phone is off, out of service, or they deleted WhatsApp entirely.

4. Calls Won’t Go Through

When you try to make a WhatsApp call to someone who’s blocked you, it won’t actually connect. You’ll hear it ringing on your end, but they won’t receive anything. This isn’t a guarantee, though it can also happen if they have no internet connection.

5. You Can’t Add Them to a Group Chat

This is probably the clearest indicator. If you try adding the person to a WhatsApp group and get a message saying you’re “not authorized” to add them, there’s a strong chance they’ve blocked you.

Why You Shouldn’t Jump to Conclusions

Even if you spot all five signs, don’t assume the worst right away. The person might have deleted their account, switched numbers, or changed privacy settings.

If you absolutely need to know, the most direct method is simply asking them though it can be awkward. Alternatively, try sending a message on another platform to see if they respond there.

The Bottom Line

WhatsApp blocking is designed to be private, so there’s no instant confirmation. But by keeping an eye on profile updates, message status, and group chat restrictions, you can make a pretty solid guess.

If this is about a close friend or family member, and you feel comfortable, just reach out in person or through another app. Sometimes, what feels like a block is just a case of bad Wi-Fi.
