Quick answer

On the same phone, install the WhatsApp Business app and register with the same number, and it will offer to transfer your chats from regular WhatsApp automatically. Make a backup first, and don't delete the old app until the process is complete. You then get a business profile, quick replies and a catalog, and you can later connect the same number to the WhatsApp Business API while still using the app.

01Before you start: 4 things not to skip

  1. Backup: go to Settings, then Chats, then Chat backup, to Google Drive on Android or iCloud on iPhone.
  2. Update both apps: regular WhatsApp and WhatsApp Business to the latest version.
  3. Don't delete regular WhatsApp: not before the transfer is finished, because the direct transfer relies on it being on the same phone.
  4. Contacts: make sure your customers' numbers are saved in your phone's address book, not only inside WhatsApp.
Watch out

Chats are not stored on WhatsApp's servers. Anything that isn't on your phone or in your backup can't be recovered by anyone.

02Steps on Android

  1. Download WhatsApp Business from Google Play and open it.
  2. Accept the terms, and the app will suggest the number you use on regular WhatsApp. Tap Continue.
  3. Allow the app to access your chats and media so it can transfer them.
  4. Enter the verification code you receive.
  5. Enter your business name, category and logo, then complete the profile: address, hours, description.
  6. Open your chats and check that they transferred before doing anything else.
Tip

If the direct transfer option doesn't appear, restore the backup from Google Drive using the same number and the same Google account that made the backup.

03Steps on iPhone

  1. Download WhatsApp Business from the App Store and open it.
  2. Accept the terms, and choose to use the same number as on regular WhatsApp.
  3. Allow the chat transfer when the app asks, or restore the backup from iCloud with the same Apple ID.
  4. Enter the verification code.
  5. Complete your business profile: name, category, logo, description, opening hours.
  6. Check your chats and media before deleting regular WhatsApp or registering another number on it.

These steps are based on WhatsApp's official guides for moving an account from regular WhatsApp to WhatsApp Business; button names may differ slightly by version, September 2026.

04What changes after you switch?

If you want to switch back later, you can move your chats to regular WhatsApp with a backup, but business tools such as the catalog don't come with you.

05Separate your personal life from your work number

Switching solves the tools problem, but not the mix-up: the family group next to customer orders, and your personal photo next to the shop's logo. The best approach: make your current number the business one, because customers already know it, and get a new number for your personal life.

Hi [Name], this number is now the business number for [Business name]. My new personal number is [Number], please save it.

Welcome after switchingWelcome

Hi [Name], this is the official account of [Business name]. You can browse our products in the catalog or type your order directly.

Away messageQuick reply

Thank you for your message. Our hours are [From] to [To], and we'll reply as soon as we open tomorrow.

06The next step: the API without leaving the app

When customers grow and more than one person is replying, or you need campaigns and an AI agent, you can connect the same app number to the WhatsApp Business API and keep replying from the app. Meta calls this coexistence, and says it syncs the last 180 days of chat history when you connect.

  • You keep the same number: no new number and no announcement to customers.
  • Some app features stop working: such as disappearing messages and view once, and broadcast lists become read-only.
  • Sending speed is capped: numbers shared between the app and the API have a fixed limit of 20 messages per second.

Key takeaways

  • Make a backup and don't delete regular WhatsApp before the transfer is complete.
  • On the same phone, chats usually transfer to WhatsApp Business automatically.
  • Make the number customers know your business number, and get a new one for your personal life.
  • Later, you can connect the same number to the API and keep using the app.
