What you'll learn

  • Read the check marks
  • Understand a lasting single tick
  • Check the profile photo
  • Check last seen and online
  • Compare with your own settings
  • Run the WhatsApp checker

How it works

WhatsApp never tells you that you were blocked. It shows delivery ticks and profile details, which change for many reasons.

The video shows one creator's approach. Where it suggests a sign "confirms" a block, read the limitations below — most signs have other explanations.

Before you start

  • WhatsApp installed on your phone

Step by step

  1. Read the check marks

    One gray tick means sent but not delivered. Two gray ticks mean delivered. Two blue ticks mean read — unless read receipts are turned off.

  2. Understand a lasting single tick

    It happens when you are blocked, but also when their phone is off, has no data, or they stopped using WhatsApp.

  3. Check the profile photo

    People can show their photo to "My contacts", selected people or nobody. A missing photo is often a privacy change.

  4. Check last seen and online

    These can be hidden for everyone in Settings → Privacy, so their absence is weak evidence.

  5. Compare with your own settings

    If you hid your own last seen, you cannot see other people's either.

  6. Run the WhatsApp checker

    Select what you observed for an explanation of what it may and may not mean.

Android, iPhone and desktop

Android
Privacy settings: tap ⋮ → Settings → Privacy.
iPhone
Privacy settings: Settings tab (bottom right) → Privacy.
Desktop / Web
Message ticks look the same; privacy settings are under the ⋮ menu → Settings → Privacy.

Signs you may notice — and what they prove

  • Messages stay on one gray check mark

    Consistent with a block, but has other causes

    One check means the message left your phone but has not been delivered to the recipient's device. This happens when blocked, but also when their phone is off, offline, or the app has been uninstalled.

  • Profile photo or 'About' info is no longer visible

    Often just a privacy setting

    Blocked users stop seeing photo updates, but people can also remove their photo or limit it to 'My contacts' or 'Nobody'.

  • Last seen or online status is not visible

    Often just a privacy setting

    Last seen and online can be hidden by anyone in Settings > Privacy, so on its own this tells you very little.

  • Voice or video calls do not connect

    Consistent with a block, but has other causes

    Calls to someone who blocked you keep ringing on your side without connecting. Poor connectivity or a switched-off device produces the same pattern.

  • Their status updates no longer appear

    Often just a privacy setting

    Status visibility is controlled per contact. They may have excluded you, removed your number from their contacts, or just stopped posting.

Important

  • Avoid repeated calls or adding the person to groups to "test" them — it can feel like harassment.

Common mistakes and troubleshooting

Single tick for a day or two
Their phone may simply be offline. Wait before drawing conclusions.

What this does not prove

  • None of these signs proves a block on its own. Only a notice shown by the platform itself is strong evidence.
  • WhatsApp offers no official way for outside services to check personal blocks.

Frequently asked questions

Can I tell without sending a message?

Not reliably. Profile details alone are usually privacy settings.
