Question

How long do I have to connect a WhatsApp number under a new display name?

Answer

Once a new display name has been approved by WhatsApp, you have 14 days to reconnect the number under the new display name. If this process is not completed within this time frame, you will need to submit the display name for re-approval as it will have disappeared from the Facebook Business Manager.
