Quick answer
Phone number: Settings > Privacy and Security > Phone Number. By default only people in your contacts see it. Last seen and online: set who sees them in Privacy and Security. If you hide yours from someone, you see only an approximate value for theirs (“recently”, “within a week”, “within a month” or “a long time ago”). You still show as online for about 30 seconds when you message someone, read their message in a one-on-one chat, or type in a chat with them.
What do you want to control?
Does this match what you see?
- You don’t want people to see your phone number.
- You want to hide when you were last online.
- You see “last seen recently” instead of a time.

Why this happens: the possible causes
What Telegram’s approximate last-seen labels mean (Telegram FAQ).
| Label | Means they were last online… |
|---|---|
| Last seen recently | Between 1 second and 2–3 days ago |
| Last seen within a week | Between 2–3 and 7 days ago |
| Last seen within a month | Between 6–7 days and a month ago |
| Last seen a long time ago | More than a month ago (also always shown to blocked users) |
- They hide their last seen from youCheck this first
You then see an approximate label instead of a time.
- You hide yours from themCheck this first
Telegram says by default, hiding yours means you can’t see theirs.
- They blocked youLess likely
Telegram says blocked users always see “last seen a long time ago”.

- All of these settings live in Settings > Privacy and Security.
How to fix it, step by step
Work through these in order. They start with the quickest, safest checks and only move to steps that sign you out or remove data later.
Fix 1: Choose who sees your phone number
Telegram says you can chat in private chats and groups without showing your number.
- Go to Settings > Privacy and Security > Phone Number.
- Choose who can see it.
Telegram says by default only people you’ve added as contacts see your number, and people who already have your number saved will always see it.

Did Fix 1 solve it?
Great, you fixed it with Fix 1. Tell us it worked, or bookmark this page in case it happens again.
Fix 2: Hide your last seen and online status
Telegram applies the same rules to your online status as to your last seen.
- Go to Settings > Privacy and Security and open the last seen setting.
- Choose who can see your last seen and online status.
Telegram says hiding your last seen from someone also hides your read time from them, and by default you won’t see theirs either. Telegram Premium users can hide theirs and still see others’.
Did it work? People you excluded see an approximate label instead of a time.
Did Fix 2 solve it?
Great, you fixed it with Fix 2. Tell us it worked, or bookmark this page in case it happens again.
Why you might still appear online
Telegram says even with your last seen hidden, people briefly (about 30 seconds) see you online if you:
- Send them a message, in a one-on-one chat or a group you share.
- Read a message they sent you in a one-on-one chat.
- Show “typing…” in their chat or a shared group.
Otherwise, Telegram says they’ll never see you online. Blocking someone also hides it.
Read times: in one-on-one chats and small groups, you can tap a message to see exactly when it was read. Telegram keeps this for 7 days only.
Who can message you
- Telegram says people can message you if they know your number or you message them first.
- Without your number, they can find you through a group you share, posts in public groups, or your public username. Don’t want that? Don’t set a username: see Telegram usernames.
- When a stranger writes first, Telegram shows an info page about them (country, when they joined, shared groups) so you can spot scams, and you can block and report them there.
- Telegram Premium users can limit new chats to My Contacts and Premium Users, or charge Stars for messages from non-contacts.
Lock Telegram on a shared device
Telegram suggests a passcode in Settings > Privacy and Security, so only you can open the app, rather than logging out.
How to know it worked
- Only the people you chose can see your number and last seen.
