Ammon News - If you need to know if you've been blocked on WhatsApp, here's how. These methods aren't completely foolproof, but they should give you a pretty good sense of whether you're blocked or not. You can use all of these steps on all versions of WhatsApp and on all devices; some of these steps are also relevant to WhatsApp Web.

Check Your Contact's Last Seen Status
The Last Seen status refers to the last time the contact used WhatsApp. Here's how you can find that see if you give you any details about whether or not you've been blocked.

Find and open a chat with the user.

If a conversation isn't open, find the user's name and create a new chat.

The Last Seen status is visible under the user's name—for example, "last seen today at 10:18 A.M."

If you can't see the user's last active date, it could mean they've blocked you.

A Conversation on WhatsApp.
Not being able to see the Last Seen status isn't necessarily an indication that you've been blocked, however. WhatsApp has a privacy setting that allows the user to hide their Last Seen status from everyone.

Blue or Gray Checkmarks?
Messages sent to a contact who blocked you always show one gray checkmark (indicating that the message was sent) but will never show a second checkmark confirming that a message was delivered, so if you don't see two blue checkmarks, meaning the message was sent and received, then it's possible your contact has blocked you.
