How Long Are Invitation Codes Valid, and How Are They Refreshed?

Category: Groups

Platforms: Android / iPhone (coming soon)

Group invitation codes are typically valid for only a limited time. This reduces the risk of a code being exposed long-term.

An invitation code can become invalid due to expiration, being refreshed by an admin, the group being disbanded, a Temporary Group expiring, the group reaching a limit, or an input error.

Invitation codes are usually refreshed or regenerated by the group admin. If a regular member finds that a code has expired, ask the group admin to refresh it.

Note

Do not post a still-valid invitation code on public web pages, social media, or unfamiliar group chats.
