# Migrating an existing WhatsApp number to Mampu AI

Already using your number on the WhatsApp API — for example with another provider or platform — and want to move it to Mampu AI? Migrating is two steps: first **turn off two-factor authentication** on the number, then **register it** using the setup guide. A number can only be active on one platform at a time, so it moves over to Mampu AI once you finish.

> **Not migrating?** If your number is on the WhatsApp Business app, see [Connecting a WhatsApp inbox](/mampu-ai/settings/connecting-a-whatsapp-inbox). For a brand-new number, see [Registering a WhatsApp official number](/mampu-ai/settings/registering-a-whatsapp-official-number).

## Before you start

* Access to the **Facebook account** that has access to the **Business Portfolio** which owns the number.
* The number is currently registered on the **WhatsApp API** (WhatsApp official) with another provider or platform.

## 1. Turn off two-factor authentication (2FA)

1. Log in to the Facebook account that has access to the Business Portfolio.
2. Open the **WhatsApp Manager** settings: [business.facebook.com/latest/settings/whatsapp\_account](https://business.facebook.com/latest/settings/whatsapp_account)
3. Turn **off** two-factor authentication (2FA) for the WhatsApp number.

## 2. Register the number in Mampu AI

With 2FA disabled, follow [Registering a WhatsApp official number](/mampu-ai/settings/registering-a-whatsapp-official-number) to register the number in Mampu AI. **Use the same details** (business portfolio and phone number) as your existing WhatsApp account so everything carries over correctly.

## You're done

Once the connection completes, your existing WhatsApp number runs on Mampu AI. Incoming messages appear in your inbox and your AI agent can reply. Manage the inbox anytime under **Settings → Inboxes**.
