"If I leave the group, will they get a notification?" "Will something pop up in the chat?" "My friend left a group I'm in and I never noticed — why?"
"Will they know I left?" actually splits into two questions — push notifications and after-the-fact discovery. The answers aren't the same. This post unpacks both and answers the user stories that show up over and over on Reddit and other community forums.
Bottom line
| What other members might pick up on | Regular group | LINE OpenChat |
|---|---|---|
| Push notification on their phone the moment you leave | No | No |
| System message in the group "XXX has left the chat" | Yes — stays in thread | Yes — stays in thread |
| Member count drops by 1 | Yes | Yes |
| Your avatar disappears from the member list | Yes | Yes |
| You don't respond when someone @-mentions you | Yes (only noticed afterward) | Yes |
So the answer to "will they know I left" is: no push notification at the moment, but the evidence stays in the group thread — whether they see it depends on whether anyone scrolls back to that chat.
Why is the system message unavoidable?
LINE deliberately treats "is this person still in the group" as public information. Two reasons:
- No ghost members. If exits were completely invisible, a group could end up with "30 members listed, but only 5 ever respond" — confusing for everyone.
- Group accountability. LINE assumes group chats are public social spaces. Who joined, who left, who was kicked, who got added — by default everyone can see it.
This is the exact opposite of the design philosophy behind one-on-one blocking — blocking is private, deliberately hidden. Leaving a group is public, deliberately announced.
Regular LINE group vs. LINE OpenChat — what's the difference?
People often blend these together, but they're two different products.
Regular group (small, invite-only)
- The "XXX has left the chat" system message is visible to everyone.
- Because these groups are typically 5–50 people, it gets spotted easily.
- After leaving, the group disappears from your chat list completely — even search can't find it.
LINE OpenChat (public/semi-public, often large)
- The system message still gets dropped in.
- But because OpenChats are often 100–500+ members, a single exit message gets buried in the chat flow quickly, so visibility is much lower than in a regular group.
- For public OpenChats, you can search the group name and rejoin yourself later (regular groups don't allow this).
That's why "does leaving a LINE OpenChat show up to everyone" is one of the most-searched LINE-group questions in communities like Reddit — large groups make people wonder whether anyone will actually catch it.
Practical rule of thumb: in a group under 50 people, someone almost certainly notices. In an OpenChat with 200+ members, unless someone happens to @-mention you, almost nobody notices you're gone.
3 real-life stories that keep showing up online
After reading dozens of community threads about "leaving a LINE group," three patterns appear over and over:
Story 1: "I left a month ago and only just got caught"
The most common one. Small work or class groups — the poster left a month earlier and only got noticed when one member tried to @-mention them and got nothing back. Takeaway: as long as nobody actively reaches out to you, it can take a long, long time before anyone realizes.
Story 2: "My ex left our mutual-friend group and nobody noticed until we caught up at a hangout the next week"
Also very typical. The system message only appears in the active chat flow — if nobody scrolls back through that group, nobody sees it. But the moment something triggers a backscroll ("hey, where's so-and-so been?"), the exit message gets dug up.
Story 3: "I rejoined an OpenChat and people remembered me — super awkward"
When you rejoin a LINE OpenChat, you're still on the same account with the same avatar. If you ever posted in that group, the people who remembered you will spot "wait, didn't they leave and come back?"

Want a truly invisible exit? Only the "stay but mute" options qualify
If your goal is "make this group stop bothering me, and don't let anyone find out" — an actual exit can't deliver that, but these 4 alternatives leave zero trace:
- Mute group notifications (most common) — long-press the group → notifications off.
- Hide the chat — swipe left on the group thread → Hide.
- Mute + push the group to the bottom of your chat list — visually it's gone.
- Just stop posting — no exit, no signal. What most people end up doing in practice.

Is it really about the group — or about one specific person?
If you're trying to leave because one specific person in the group has been making you uncomfortable — leaving you on read, avoiding you, ghosting your messages — leaving the group won't fix it. The real question you're trying to answer is "have they already blocked me one-on-one?"
LINE blocks work the opposite of group exits: LINE deliberately hides block status from the blocked person. Your message still shows "Sent," their avatar is still there, everything looks normal — but on their end, nothing arrives.

Frequently Asked Questions
When I leave a LINE group, does the other person's phone get a push notification?
No. Leaving only drops a system message in the group thread — there's no push to anyone.
After I leave, if someone messages the group, will they see I'm gone?
Not directly, but your name is no longer on the member list. If they open the member list, they'll see you're missing.
How long does "XXX has left the chat" stay visible to other members?
As long as the group still exists and the message hasn't been buried by enough new chat, it stays forever. LINE system messages behave like normal messages — they stay in the chat history indefinitely.
Will my LINE OpenChat exit appear in friends' VOOM or feed?
No. LINE OpenChat exits stay inside that OpenChat — they don't get pushed to VOOM or any timeline.
After I leave the group, can the other person still message me directly?
Yes — anyone in that group who is still your LINE friend can DM you one-on-one. The group exit only removes you from the group; it doesn't break the friendship. The only thing that breaks one-on-one messaging is a one-on-one block.
