Blocking is private on Telegram: the blocked person gets no notice. What they see instead is a profile that seems to have stopped updating, which is why a block is easy to confuse with someone who simply hides their last seen.
Quick answer
If someone blocked you, you see last seen a long time ago, no profile photo updates, messages stuck at one tick and calls that do not go through. One sign alone is not proof; all of them together usually are.
1. Signs that someone blocked you
- Their status shows last seen a long time ago. Telegram's FAQ says you always see this when someone has blocked you.
- You stop seeing their profile photo or its updates.
- Your messages stay at one tick and never get the second tick.
- Your calls do not go through.
Each of these can also have another reason, such as strict privacy settings or an inactive account.
What each status means: Telegram last seen.
2. What a block changes
| The blocked person | Can they? |
|---|---|
| Send you private messages or call you | No. Messages do not reach you. |
| See your last seen and profile photo updates | No |
| Get a notice that they were blocked | No |
| Read your messages in a shared group | Yes. A block covers private chats, not groups you are both in. |
3. How to block someone
- Open the chat with the person and tap their name.
- Tap the three-dot menu.
- Choose Block User and confirm.
You can also add people in Settings › Privacy and Security › Blocked Users. For spam, use Report as well, so Telegram can act on the account.
4. How to unblock
Open Settings › Privacy and Security › Blocked Users, tap the person and choose Unblock. Messages sent while they were blocked are not delivered later.
5. Blocked by a person or limited by Telegram?
If you cannot message people who are not in your contacts, the block may come from Telegram, not from one person. That is a spam limit, often after reports, and it has nothing to do with a single contact.
- Message @SpamBot in Telegram to see whether your account is limited and until when.
- A frozen account can still read chats but cannot send messages; appeal from the app.
