Without preparation, the only admin leaves and a random participant becomes admin without knowing what to do. With an admin team and 9bot, the group gets reminders, the new admin takes over and new members get a welcome and the team list. **Direct answer:** If the admin leaves and there are other admins, nothing changes for the group. If they were the only admin, the Help Center says WhatsApp picks a random participant as the new admin. If the admin uses the Change number feature, the groups are notified and they stay in them. If they lose their phone, they can register the same number on another device. Inactive accounts are generally deleted after 120 days, and then the admin leaves the groups. **In short:** - Only admin left: a random participant becomes admin. - Change number keeps the groups; a lost phone is solved by registering the number again. - Prevention: always at least two active admins. ![Want to automate your WhatsApp groups?

WhatsApp does not let you choose who, and support cannot change admins afterwards. In a professional group, that can hand control to someone outside the company. Before leaving a group you run, promote at least one trusted person. See [how to add an admin](https://9bot.com.br/en/add-change-remove-whatsapp-group-admin/). ## When the admin changes or loses their number **Planned change:** use **Settings > Account > Change number** on the phone. According to the [Help Center](https://faq.whatsapp.com/498754122134583/), groups are notified automatically and the admin stays in them. The change cannot be made on WhatsApp Web or Desktop. **Lost or stolen phone:** get a SIM with the same number from the carrier and register WhatsApp on a new device. The [Help Center](https://faq.whatsapp.com/1007324800132703/) explains that this logs out the lost device. **Cancelled number:** if the number does not come back and the account goes unused, the [Help Center](https://faq.whatsapp.com/828406668498455) says inactive accounts are generally deleted after 120 days. Until then, the admin is still listed in the group but does not answer. ## Continuity plan for professional groups 1. **Two or more admins** in every group, from different teams or shifts. 2. **A company number** as the main admin, instead of an employee's personal number. 3. **Regular review** of the admin list when someone changes role or leaves the company. 4. **A group register**: name, link and admins of each group. With 9bot connected to a company number that is admin, rules, welcomes and moderation keep running when someone on the team leaves. 7-day trial; with the coupon **FIRST9**, monthly plans are 50% off for the first 3 months after the trial.
