How to Know If Someone Blocked You on Telegram [2025 Guide]

Have you ever felt ignored on Telegram but couldn’t be sure if you’ve been blocked? This uncertainty can be frustrating. Knowing whether someone has blocked you is not just about closure—it’s also about understanding your digital boundaries. In this guide, I’ll walk you through how to know if someone blocked you on Telegram, identify the key signs, rule out potential technical issues, and introduce TGSeen , a powerful tool for uncovering last-seen activity on Telegram.

4 Significant Signs to Know If Someone Blocked You on Telegram

If you suspect that someone has blocked you on Telegram, there are specific indicators to look for. Here are the top four signs:

Persistent Single Checkmark on Messages

One of the most obvious indicators is the checkmark system in Telegram. Normally, a single checkmark means the message has been sent, and a double checkmark signifies it’s been delivered. If your messages to someone persistently show a single checkmark, it’s possible they’ve blocked you.

Changes in Activity Status Visibility

Another sign to tell if someone blocked you on Telegram is the sudden disappearance of their “last seen” or “online” status. When someone blocks you, Telegram restricts your ability to view their activity updates. Instead, you might see a vague message like “Last seen a long time ago.” If you can no longer see when they were last active, it’s a strong indicator of being blocked.

Profile Picture Reverts to Initials

When blocked, the person’s profile picture often reverts to the default initials. This is because blocking restricts your access to their profile updates, including their avatar changes.

Failed Calls to the Person

If you try calling someone on Telegram and it never connects, this could indicate you’ve been blocked. Telegram doesn’t explicitly notify you, but consistent call failures are a red flag.

Technical Issues That Could Mimic Signs of Being Blocked

Before jumping to conclusions, it’s essential to consider other factors that might create similar signs:

  • Network Issues: Poor connectivity can delay message delivery and make calls fail.
  • Telegram Server Downtime: Periodic outages on Telegram’s servers could make it appear as though your messages aren’t being delivered.
  • Privacy Settings: The person may have customized their settings to hide their activity or profile picture.
  • Account Deactivation: If someone deactivates their Telegram account, it could appear as though you’ve been blocked.

If you’re unsure, a tool like TGSeen can provide clarity by accurately tracking someone’s last-seen activity.

How to Confirm If You’ve Been Blocked

If the signs aren’t enough, here are two reliable methods to confirm if you’ve been blocked:

Cross-Check With Another Account

One of the simplest ways is to create a new Telegram account or borrow a friend’s. Search for the person’s profile. If their status, profile picture, and activity are visible from the new account but not from yours, you’ve likely been blocked.
