What is the LINE OpenChat member limit? 7 ways to grow your OpenChat
SocialContactApp · Fu Xin Co., Ltd. · Updated 2026-10-05
A LINE OpenChat holds up to 5,000 members, while a regular LINE group holds about 500. Growing an OpenChat takes more than sharing the link: its name, joining settings and how you run it all matter. Here are the official rules and practical ways to grow.
LINE OpenChat member limit: up to 5,000
According to LINE, an OpenChat holds up to 5,000 members, and the admin can set a lower limit in the OpenChat settings; a regular LINE group holds about 500.
| LINE OpenChat | Regular LINE group | |
|---|---|---|
| Member limit | Up to 5,000 (admin can set a lower limit) | About 500 |
| How people join | Invite link, QR code, OpenChat search | Invitation by a member, QR code or link |
| Display name | A different nickname and picture in each OpenChat | Your own LINE profile |
| Joining condition | Anyone, join password or admin approval | Anyone invited can join |
Once the limit is reached, no one else can join; ask the admin to raise the limit or open another OpenChat.
Three joining settings that change how fast you grow
- Anyone can join: the lowest barrier and the fastest growth, but unrelated people join more easily.
- Join password: only people with the password can join; good for courses or member groups.
- Admin approval: you can screen members, but approval takes time and growth is slower.
To grow quickly, open the OpenChat first and switch to approval once the numbers are stable.
7 ways to grow your OpenChat
- Share the invite link and QR code on your Official Account, social media, blog, business cards or shop.
- Make it easy to find: put the words people search for (place, topic, audience) in the name, description and category.
- Post valuable content regularly, such as information, deals or events, so members stay and invite friends.
- Offer a reason to join, such as a handout, a discount code or event seats.
- Cross-promote with related OpenChats that are not competitors.
- Run ads or work with creators to bring people from other platforms to the invite link.
- Use a member-adding service when you need a basic size quickly, then combine it with the methods above.
When does a member-adding service make sense?
Service accounts join the OpenChat, which suits a new OpenChat that needs a basic size or an event OpenChat that must reach a certain size quickly. It does not bring natural engagement, so run the community at the same time.
At SocialContactApp a standard OpenChat costs USD 0.124 per member (about NT$3.97); orders usually start on the day they are placed and gain from a few dozen to about a hundred members a day. More in Can you buy LINE OpenChat members?
Why the member count is not growing
- The member limit set by the admin has been reached.
- Joining needs approval and requests are still waiting.
- The invite link was reset and the old link no longer works.
- The name or description is too vague for people to find it.
