How to Know if You’ve Been Blocked on WhatsApp (2026 Guide)

WhatsApp does not send a notification when someone blocks you due to strict user privacy policies. However, by observing a few key indicators, you can confirm your status with 99% accuracy.

Here is the step-by-step checklist to determine if you have been blocked:

1. "Last Seen" and "Online" Status

If you can no longer see a contact's Last Seen timestamp or their Online status (which you were previously able to see), this is the first red flag.

• Note: The user might have simply changed their privacy settings, so this is not definitive proof on its own.

2. Profile Photo Disappearance

When you are blocked, you will no longer see updates to the contact's profile picture. Often, the photo disappears entirely and is replaced by the default grey silhouette icon. If the photo was visible before and suddenly vanished, it is a strong indicator.

3. Message Delivery Status (The Single Tick Rule)

Pay close attention to the checkmarks next to your sent messages:

• Single Grey Tick: Message sent from your phone but not delivered to the recipient.

• Double Grey Tick: Message successfully delivered to their phone.

• Blue Ticks: Message has been read. If your messages remain stuck on a single tick for several days, you have likely been blocked.

4. Attempting a WhatsApp Call

Try calling the contact via WhatsApp. If the call never connects and stays on the "Calling" screen without ever switching to "Ringing," this is one of the most reliable signs that you are blocked.

5. The Group Test (The Definitive Method)

This is the most accurate way to confirm a block:

1. Create a New Group on WhatsApp.

2. Try to add the person you suspect has blocked you to this group.

3. If you receive an error message saying "Could not add participant" or "You are not authorized to add this contact," it is a certainty that they have blocked you.
