To know if someone blocked you, the signs vary depending on the communication platform:
- On Facebook, if you can't find their profile in your friends list and searching for them shows no profile or "Content not available," it's likely you are blocked. Also, you cannot message them or see their posts.
- On WhatsApp, indicators of being blocked include not seeing the contact’s last seen or online status, no profile photo updates, all messages showing a single gray check mark (sent but not delivered), and calls not going through.
- On Instagram, if you search for the person's profile and it says "User not found," or you see their profile but no posts with a message like "This Account is Private," or you can't see messages delivered, you may be blocked. Also, if their comments on your posts take you to a blank profile, it indicates blocking.
- For phone numbers, signs include calls going straight to voicemail or playing a message like "number temporarily out of service," text messages not showing "delivered," and being able to call them from another number while your calls still don’t get through.
- More generally, trying to view their profile or contact from another account or device and seeing content that appears for others but not you is a strong sign of being blocked.
There is no universal definitive notification of blocking due to privacy, but these indirect signs can help determine if someone blocked you on popular platforms and phone numbers. Each platform has its own cues for blocking detection based on visibility, message delivery, and contact status.
