LINE OpenChat vs LINE group: members, anonymity and joining compared

SocialContactApp · Fu Xin Co., Ltd. · Updated 2026-10-05

Many people mix up LINE OpenChats and LINE groups, but their member limits, member identity and joining methods are different. Pick the wrong one and running or promoting it gets harder later.

When to use an OpenChat and when a group

Choose an OpenChat when members do not know each other, there may be hundreds of them, or strangers should be able to find and join it. Choose a regular group when members know each other, the group is small and identities matter.

For business, OpenChats suit recruiting and fan communities; for one-to-one service and broadcast messages, add a LINE Official Account.

Can you convert one into the other?

No. They are different features and cannot be converted; create a new OpenChat or group and invite the members over.

Growing members works differently

An OpenChat can grow through its link, QR code and OpenChat search, and through member-adding services; a regular group mostly grows by members inviting each other.

SocialContactApp offers OpenChat services (20001, 20002, 20005, from USD 0.124 per member) and a regular-group service (20007, currently mainly for Taiwan, USD 0.124 per member, 50–490 per order). For OpenChat limits and growth methods see What is the LINE OpenChat member limit?
