Google Meet codes do not all follow one expiration rule. Before reusing an old address, identify where its code was originally generated. The app containing the link today is not necessarily the app that created it, so a pasted Calendar invitation can be misleading evidence.
Identify the code’s origin
Ask the organizer whether the room came from Calendar, the Meet homepage, Gmail, Chat, a nickname, or another supported product. Google’s current guidance says Calendar-generated codes expire when they have not been used for 60 days and are not associated with future Calendar events. Both conditions matter for that specific category.
Apply the correct lifecycle
Google describes several other origins, including the Meet homepage and Gmail, as expiring 365 days after last use. Nicknamed meetings expire when everyone leaves, and breakout-room codes expire when the main meeting ends. Do not apply one of these rules to every link merely because the addresses look similar.
Confirm before redistributing
Check the linked official table when planning a future session or investigating an expired-code message. Reusing a code is also an access decision: old recipients may still retain its address even when the code remains valid. If the organizer creates a replacement, update the authoritative invitation and notify participants explicitly. A working room address does not prove that the scheduled appointment, guest list, or host configuration is current. Keep a record of which invitation supersedes the previous one so guests do not divide between an old room and a new room at the meeting time.
