How can you tell if someone has blocked you on WhatsApp?

The call isn't going through, but for some reason, they can still text. I don't know either—I was blocked once and couldn't call, but messages still came through. And I could see their profile.

It is impossible to 100% confirm a block on WhatsApp because the messenger does not specifically notify about blocks or provide clear indicators. This is essentially done to protect user privacy. However, there are indirect signs that, when combined, may indicate that another user has blocked you:
- You will not see confirmation that your message has been read by the other user (the double blue checkmarks);
- You cannot see updates to the contact's profile photo;
- You cannot make outgoing calls to them;
- You cannot add this contact to a group where you are an admin;
- You cannot see the contact's last seen time or any other statuses.
If you notice all these signs, it may (but not 100%) mean that the user has blocked you. However, there could be other reasons for this as well.

WhatsApp does not notify you about being blocked; you can figure it out from the avatar. If there was one, it becomes invisible immediately after being blocked. Otherwise, you'll have to guess.

But also, if someone isn't responding to you, why would you need such a person anyway?

When blocked, also:

No matter how many messages you send, they appear sent but never reach the recipient. It looks as if the message hasn't been read, but in reality, it wasn't delivered due to the block, even though it appears sent.

Calls seem like they don't connect—just ringing and that's it. You think you're calling, but the recipient doesn't actually receive the call. However, that was the case a year ago regarding calls; I'm not sure about now. But regarding avatars and messages, everything remains the same. Statuses also become invisible.

When you send messages to someone who has blocked you, you will see a single checkmark below the message, whereas if you are not blocked, you will see two checkmarks indicating it has been delivered.

1. The profile picture is no longer visible. Messages are not delivered (1 checkmark). 3. The status is not visible. This is 100% confirmation that you have been blocked. Of course, if the person never had a photo to begin with, it's harder to tell.

That's a glitch with the internet/WhatsApp itself, not a block.
When blocked, you can't see anything.

Notifications about messages being read and when the user was last online can be turned off without blocking. I have these settings disabled for everyone. I don't need everyone to know when I was last online and when I read messages, it feels like some kind of surveillance. And when you block someone, there's actually a message that pops up saying the person won't know you blocked them. By the way, calls and messages from blocked contacts don't go through for me either.

That means they're using a proxy.
