How can you know if someone has deactivated their WhatsApp account?

If someone has deactivated their WhatsApp account, you will not be able to see their last seen status, profile picture, or online status. Additionally, you will not be able to send them messages or call them on WhatsApp.

If you try to send a message to someone who has deactivated their WhatsApp account, you will see a single tick mark next to the message, indicating that the message has been sent but not delivered. However, the message will never be delivered, and you will not receive a delivery receipt or a read receipt.

If you are not sure whether someone has deactivated their WhatsApp account or is just ignoring your messages, you can try calling them on WhatsApp or sending them a message asking if they are still using the app. If they do not respond, it is possible that they have deactivated their account.

Note that if someone has deleted their WhatsApp account, you will not be able to see their last seen status, profile picture, or online status, and you will not be able to send them messages or call them on WhatsApp. However, you will still see their name and profile picture in your chat list until you clear your chat history. If you try to send a message to someone who has deleted their WhatsApp account, you will see a message that says "This phone number is no longer registered on WhatsApp."
