Whatsapp now permits sender transfers between Business Accounts, so if you signed up for WhatsApp using the WhatsApp Business API outside of Twilio (either directly with WhatsApp, or through a different Business Solution Provider), you can now move that existing WhatsApp Business number to the Twilio platform.
Moving an existing WhatsApp number to Twilio to use for WhatsApp
If your number was activated for WhatsApp using one of the WhatsApp mobile apps, and not the Business API,
There are two ways to achieve this:
- Host or port the number to Twilio, and then proceed with the standard WhatsApp onboarding process
- (If you are eligible) Utilize our "Bring Your Own Number" offering.
For details and eligibility requirements for both of these options, see Can I activate my own phone number for WhatsApp on Twilio?
If these options do not work for you, we recommend buying a Twilio phone number to activate for WhatsApp. Many types of Twilio phone numbers can be enabled for WhatsApp messaging, even if they are not SMS-capable. For more info, see Which Twilio Phone Numbers are Compatible with WhatsApp?
